  • Accessing .NET functionality from a macro in a VSTO Excel workbook

    - by Daniel DiPaolo
    A while back, I built an Excel workbook for someone else using VSTO SE, and there's functionality in the accompanying DLL that they'd like to be able to use in a VB macro in the workbook. Short of rebuilding the workbook with a control that does what they want, is there a way they can just hook into the necessary function somehow via some sort of macro call? Does the macro have any sort of visibility into the functionality within the VSTO-built DLL that is associated with the workbook?

  • How do I convert Word files to PDF programmatically?

    - by Shaul
    I have found several open-source/freeware programs that allow you to convert .doc files to .pdf files, but they're all of the application/printer driver variety, with no SDK attached. I have found several programs that do have an SDK allowing you to convert .doc files to .pdf files, but they're all of the proprietary type, $2,000 a license or thereabouts. Does anyone know of any clean, inexpensive (preferably free) programmatic solution to my problem, using C# or VB.NET? Thanks!

    I wrote a T-SQL query which includes a test for valid EmployeeNo. If the EmployeeNo is not valid, I do the following: RAISERROR(5005, 10, 1, N'Invalid Employee No') return @@Error Back in VB.Net I test the sql exception and found that when the Employee No is invalid the error.number is not 5005 as I would expect, but 2732. What is the explanation for this? Thank you.

  • Microsoft Chart control converts \n in file names to newline characters.

    - by xpda
    I am using a Microsoft Chart control (system.windows.forms.datavisualization.charting.chart) in a Windows forms application, vb.net 2008. I use folder paths for the x values in a pie chart. Chart control converts a name like c:\newfolder into c:[newline]ewfolder. I tried adding a slash, making it c:\\newfolder, but this only changes it to c:\[newline]ewfolder. Is there a workaround for this behavior?

    I am working with VB.NET.. i have a DataTable called "QUESTION", containing 3 fields: QuestionNumber (unique integer key) QuestionText QuestionType In my SQL Server database I created a Table called "QUESTION" with the same fields.

How do i have to change my database setup, that the original QuestionNumbers are copied into the database?

  • CSS Calendar Display

    - by Steven
    I created my own custom date picker consisting of an ASP TextBox, Button, and Calendar complete with CSS styles, javascript code, and event handling vb code. I want to use this date picker multiple times on my form. I know the wrong way to do this would be to copy all the code and just adjust each name accordingly. How can I put those controls, styles, and code into a single entity?
