Merging Text Files

Using a command line argument, you can instruct Visual CUT to merge any number of text files.

For example, this feature allows you to append text or csv exports to an existing files. Another

typical use scenario is to append a csv export (which doesn’t include column headers) to a

single-line text file that provides the column headers.

The command line argument structure is as follows:

…

"TXT_MERGE:Text_File_List>Text_File_Target>Top_Rows_To_Remove"

The parameters (after the ":") are separated by a ">" and are as follows:

1. Text_File_List: comma separated list of the source files in the order they should be merged.

If all source files share the same folder, you can specify the full path just for the first file.

If a source file is not found, a warning is written to Failure.log and that file is skipped.

2. Text_File_Target: the file path & name for the resulting merged file. If the path is the same

as the first source file, you may specify just the file name.

3. Top_Rows_To_Remove: the number of top rows to remove from each file being merged into

the first file. This is useful if the first file already provides column headers that should be

removed from the following files. Use ‘0’ to indicate

no rows should be removed.

For example:

"TXT_MERGE:c:\temp\File1.txt,File2.csv,File3.csv>c:\temp\Result.csv>0"

Dynamic Field Names

You can use field or formula names within the command line argument (just like you drag &

drop fields & formulas into the various options in the 3rd tab within Visual CUT. The dynamic

content of these fields/formulas would be substituted into the command line argument.

Replacing Content in Text Files

Using a command line argument, you can instruct Visual CUT to replace any number of strings

in a text file with specified substitutions. For example, this feature allows you to remove a

Carriage Return and Line Feed at the end of csv file exports.

The command line argument structure is as follows:

…

"TXT_Replace:InFile||OutFile||find1>>replace1::find2>>replace2||Options"

The parameters (after the ":") are separated by a "||" and are as follows:

1. InFile: the file path & name for the source text file.

2. OutFile: the file path & name for the resulting text file.

- If no OutFile is specified, the source file gets updated

if the target folder doesn’t exist, Visual CUT creates i

- if no path is specified (just name) the path of the source file is used

3. Find & Replace Pairs: unlimited number of find and replace elements.

Each "find" element is separated from its "replace"

element by a ‘

’.

Each pair is separate

d from the next pair by a ‘

’

- To specify special string characters, such as Carriage Return or Line Feed,

use Chr() expressions (e.g., Chr(10) or Chr(13).

To remove strings, specify them in the ‘find’ and leave the ‘replace’ as blank

4. Options: Leave blank, unless you wish to use a special option.

- Specify END if you wish the substitution to occur only at the end of the file.

For example, to remove Carriage Return and Line Feed at the end of a text file, use this

command line argument:

…

"TXT_Replace:c:\temp\Input.csv||Result.csv||Chr(10)>>::Chr(13)>>||End"

Dynamic Field Names

You can use field or formula names within the command line argument (just like you drag &

drop fields & formulas into the various options in the 3rd tab within Visual CUT. The dynamic

content of these fields/formulas would be substituted into the command line argument.

Removing Blank or Short Lines in Text Files

Using a command line argument, you can instruct Visual CUT to remove blank or short lines in

text files. This is typically useful when one of the text export formats generates a file with

unwanted blank lines or lines with just delimiters.

The command line argument structure is as follows:

…

"TXT_Remove_Short_Lines:InFile||OutFile||Max_Length_To_Remove"

The parameters (after the ":") are separated by a "||" and are as follows:

1. InFile: the file path & name for the source text file.

2. OutFile: the file path & name for the resulting text file.

- If no OutFile is specified, the source file gets updated

if the target folder doesn’t exist, Visual CUT creates it

- if no path is specified (just name) the path of the source file is used

3. Max_Length_To_Remove: Lines with that specified length or shorter would be removed.

For example, to remove all lines that are only 3 characters or shorter:

…

"TXT_Remove_Short_Lines:c:\temp\Input.csv||Result.csv||3"

Dynamic Field Names

You can use field or formula names within the command line argument (just like you drag &

Removing GUIDs from png Files Referenced in HTML Exports

This approach is designed to address a use scenario where each time you export a report to

HTML, image files are created (charts, logos, etc.) with different names. The references to these

files use a GUID to make the file name unique, like this:

<img src="Sales{EF6A442D-0DDA-436A-A178-2410853A7E05}.png"

Where the Sales portion is based on the export file name.

In most

cases, the image files actually don’t need unique

GUIDy names and we can DeGUID

(remove the GUID portion) from the file reference and from the actual png file name.

The DeGUID process detects if each png file is unique or a clone of another image within the

same report (typical in cases of logos repeating on each page). If the png is not a clone (typical in

reports with multiple charts), the GUID is replaced by an incrementing number (Sales_1.png,

Sales_2

.png, etc.). This ensures the local and web folders don’t accumulate unique GUIDy

names each time the scheduled process runs. It also saves space because while Crystal exports

the same logo on different pages as multiple png files, the DeGUID process in Visual CUT

automatically consolidates these clones as a single file.

You can elect to either delete the GUIDy png files (typical in cases the images are static (logos).

Or you can elect to rename the png files to match the renamed references in the HTML source.

The command line argument structure is as follows (all in 1 line):

"TXT_DeGUID_png:InFile||Options"

The parameters (after the ":") are separated by a "||" and are as follows:

1. InFile: the file path & name for the source HTML file.

2. Options:

DeleteLinkedFile to delete the referenced png files (Scenario 1 above)

RenameLinkedFile to rename (DeGUID) the referenced png files (Scenario 2 above).

Otherwise, None

For example, the following directive:

"TXT_DeGUID_png:c:\temp\Sales.htm||RenameLinkedFile"

Would remove all GUIDs from png file references in the HTML export. It will also rename the

referenced png files by removing the GUIDs from their file names.

More complex scenarios (you wish to rename references to a logo image to a static name that

doesn’t depend on the

export file name) can be handled by the more complex command line

argument described in the next section (TXT_Replace_Tokens).

Dynamic Field Names

You can use field or formula names within the command line argument (just like you drag &

drop fields & formulas into the various options in the 3rd tab within Visual CUT. The dynamic

content of these fields/formulas would be substituted into the command line argument.

Replacing Content in Text/HTML Files

–

Token Approach

This approach allows you to change the content of exported TEXT or HTML file.

The command line argument structure is as follows (all in 1 line):

"TXT_Replace_Tokens:InFile||OutFile||Start1^^End1^^replace1^^Location1^^Options1

::Start2^^End2^^replace2^^Location2^^Options2||Global_Options"

The parameters (after the ":") are separated by a "||" and are as follows:

1. InFile: the file path & name for the source text file.

2. OutFile: the file path & name for the resulting text file.

- If no OutFile is specified, the source file gets updated

if the target folder doesn’t exist, Visual CUT creates it

- if no path is specified (just name) the path of the source file is used

3. Find & Replace Directives: find and replace directives (separated from each other by "::").

Each directive has 5 elements separated by a ‘

’:

- Start Token (in the example above, this would be

<img src="

- End Token (in the example above, this would be

- Replace with: text to replace the text found between start and end tokens

- Location: LAST for last found match, ALL for all, 1 for 1

found match, 2 for 2

…

- Options: RenameLinkedFile if you want to rename a matching file.

DeleteLinkedFile to delete a matching file (if clean file name already exists).

Otherwise, None

4. Global Options: Leave blank

For example, the following directive:

"TXT_Replace_Tokens:c:\temp\Sales.htm||||<img src="^^" border="0" width="52px"

height="32px"></div>^^LionHead.png^^ALL^^RenameLinkedFile||"

you can replace multiple image files, typically named as variations of:

Output_File{1A49A55D-544F-472F-B40F-5B7062C3D47A}.png

with a single image file.

"TXT_Replace_Tokens:c:\temp\Sales.htm||c:\temp\Sales.htm||

<img src="

" border="0" width="52px" height="32px"></div>^^MyLogo.png^^ALL^^RenameLinkedFile||"

will change all references to an image with dimensions of 52x32 with a single static reference to

MyLogo.png. Due to the

RenameLinkedFile

directive all the temporary matching files such as

Output_File{1A49A55D-544F-472F-B40F-5B7062C3D47A}.png

Will be renamed to MyLogo.png

This has 2 effects:

Less clutter in the export folder because multiple image files may be replaced by a

single image file

Less files need to be attached to an email message or uploaded to a web server

The web server and the client browser can cache MyLogo.png, improving

performance

Dynamic Field Names

You can use field or formula names within the command line argument (just like you drag &

drop fields & formulas into the various options in the 3rd tab within Visual CUT. The dynamic

content of these fields/formulas would be substituted into the command line argument.

Inserting Base64-Encoded Files Inside Text/XML

This option was developed for a customer who needed to export invoice data to an XML file

containing an embedded image encoded with Base64 (a method that converts from binary to text

representation). The XML file is then transmitted to a business partner using SFTP_Upload.

The process takes the following steps:

A TEXT export creates the XML file with a reference to a file that should be

embedded at a particular location. The reference has the following structure:

[Insert_File_Base64:file_path_and_name]]

for example,

[Insert_File_Base64:C:\Temp\Invoice_32556_image.pdf]]

Using a TXT_Replace_Base64 command line argument directs Visual CUT to

search the XML file, locate such references, and replace them (including the

surrounding tags) with the Base64 encoding of the specified file.

The command line argument structure is as follows (all in 1 line):

"TXT_Replace_Base64:InFile||OutFile||Options"

The parameters (after the ":") are separated by a "||" and are as follows:

1. InFile: the file path & name for the source text file.

2. OutFile: the file path & name for the resulting text file.

- If no OutFile is specified, the source file gets updated

if the target folder doesn’t exist, Visual CUT creates it

- if no path is specified (just name) the path of the source file is used

3. Options: Leave blank

Notes:



You can have any number of references embedded in the exported text file. Visual CUT

will replace all of them.



You can use field or formula names within the command line argument (just like you

drag & drop fields & formulas into the various options in the 3rd tab within Visual CUT.

The dynamic content of these fields/formulas would be substituted into the command line

argument.

Changing Text File Encoding

This option was developed for a customer who needed to change the encoding of a text export

from ANSI to UFT-8.

The command line argument structure is as follows:

…

"TXT_Encode:InFile||OutFile||fromEncoding>>toEncoding||Options"

The parameters (after the ":") are separated by a "||" and are as follows:

1. InFile: the file path & name for the source text file.

2. OutFile: the file path & name for the resulting text file.

- If no OutFile is specified, the source file gets updated

if the target folder doesn’t exist, Visual CUT creates it

- if no path is specified (just name) the path of the source file is used

3. The original and new encoding, separated by

a ‘

’.

4. Options: Leave blank

For example, to convert from ANSI to UTF-8:

…

"TXT_Encode:c:\temp\ {@invN}.xml||c:\temp\{invN}.xml||windows-1252>>utf-8||"

…

"TXT_Encode:c:\temp\ {@invN}.xml||||windows-1252>>utf-8||"

ODBC Export Functionality

Visual CUT (for Crystal 9 and above) provides ODBC Export options that are not available in

Crystal alone. As shown below, the ODBC Export Options dialog allows you to select Abort

(default Crystal action), Append, or Replace

as the action when the target table already

exists:

Note: the Table Name is controlled by the

Export File Name (that option is not on the

dialog shown here but on the main

email/export processing options tab of Visual

CUT). Since that option accommodates

dynamic content, you can control the table

name using fields/formulas in the report…

Append Functionality

By selecting append, you can add data to an existing table. One use for this is for recording

snapshots of data over multiple periods of time. For example, your database may show current

inventory levels or current account balances but it is very difficult to generate a report that shows

inventory levels or account balances at the end of each month for the last few years. By

scheduling Visual CUT to run at the end of each month and append information reflecting the

inventory levels or the account balances at that time, you enable easy tracking of that information

over time. In Data Warehousing jargon, this is called a snapshot data warehouse.

Another use scenario is to record the fact that certain records were processed by Visual CUT and

to avoid duplicate emails. For example, as orders arrived throughout the day, you can schedule

Visual CUT to run every 5 minutes and email order confirmation messages to the customers. By

appending to an ODBC table, you can record which orders have already been confirmed.

Alternatively, you can use the Skip_Recent command line argument described in the section

Avoiding Duplicate Processing on page: 52.

Another use scenario is to Extract, Transform, and Load (ETL) data into a data warehouse

or across data sources without needing expensive ETL tools or consultants.

Replace Functionality

A typical use for the Replace option is to generate temporary tables for use by other

processes or crystal reports. For example, Crystal Reports can't aggregate other aggregate

values (e.g., average group totals) and can't sort groups based on formulas that use aggregate

values. However, you can create a batch file that calls Visual CUT twice: first to export a report

with aggregate values to a temporary table and then to process a 2

report that uses the

temporary table as input.

Page 220

Capturing & Processing Incoming Emails

Visual CUT can automatically capture incoming emails from your email server to a database

table. A Crystal report using the data in that table can then be processed in Visual CUT to trigger

reactions to that email, such as:



Export/Print/FTP/Email information or reports



Update databases using After_Success_SQL



Trigger other applications or Visual CUT processes using After_Burst_Batch

Use Scenarios

Here are a few examples of the types of workflow automation this enables:



Requesting a Report via a Simple Web Form or via Email:

A manager, employee, customer, or supplier can use a simple web form (no web

application required) to request a report.

The information gets emailed to your email server

Visual CUT captures the email into the EMAIL_CAPTURE table.

A Crystal report using that table inside Visual CUT uses After_Burst_Batch to

trigger another Visual CUT process by specifying a report to run, parameters,

email destination, etc.

The triggered Visual CUT report runs and emails the output to the requesting

employee/customer.

Note: using the same exact process, you can let customers request information or

reports by sending an email. For example, a customer may request information about

the status of their order, the balance in their account, etc.

Here is a sample email from ABP Reports’

Boomerang system, which uses this

technique, allowing users to request reports via email by simply clicking on a

hyperlink:
