• Visual Basic MSComm32.ocx in VB.Net problem

  Hi everyone. A while ago I wrote a library which helps me simply text operations, serial communications, PLC interaction using OPC Automation, etc... My problem is with the vb6 serial control mscomm32.ocx. In my computer, I can use it with no problem. Everything works fine when testing serial control and my forms can open sucessfully. When I try to run a winform that uses Serial library (mscomm32.ocx) in a computer that doesn't have VB6 installed, I get the error "Common Language Runtime Debugging Services. Application has generated an exception that could not be handled. PRocess id=0xe0 (224). Thread id= 0x6f4 (1780)" I started ...Show All

  Dear All. I am using VC 2005, writing a chunk of code like this... #ifdef USE_LICENSING #include<file1.h> code... code.. #endif the editor grays out the code between then ifdef and endif tags, I can use features like intellisense only if i comment out ifdef and endif tags.. anyone aware of this Satish Boston,MA.

• Visual Basic Making a Database

  Hi i was wondering if there are any tutorials around on creating databases in vb6 and vb.net Yes, there are tons of them. However, do you want to create the actual database, or do you just want to connect to it ADOX will create .mdb files, and if you have a SQL database installed, you can use ADO.NET to run the SQL that creates a database. You should probably search the web for a question like this, www.codeproject.com would be one place that certainly has tutorials on this stuff, although not in VB6. VB6 is pretty much dead, if you're learning, I would not bother with it. ...Show All

• Software Development for Windows Vista Vista backward compatibility

  Hi, is MS Vista supposed to be backward compatible with the other MS win32 operating systems I mean, if I have an application running on MS Windows XP, can it run on Vista as well thanks.

• Visual Studio Express Editions Adding a second form

  In NET 2003, I read this instruction in a book: "Visual Basic .NET requires that you specifically declare a variable of the form's type before you use a second form." Assuming two forms frmMain and frmHelp, I would do this in frmMain: Dim frmHelp As New frmHelp frmHelp.ShowDialog() But in NET 2005 (Express) it seems to work without the Dim: frmHelp.ShowDialog() Has the requirement changed Hi Visual Basic 2005 now supports shared forms which means that you can reference a form without having to first instantiate a new instance of it. You can also access your forms v ...Show All

• Windows Forms a datagridview and combobox problem

  I am using VS 2005 Professional.   I have a master-detail form on which I have a datagridview(detail) that is bound to a table. Within that grid, one of the columns displays values from another table using a combobox. Under normal circumstances this all works quite well. However, if you go to the new record at the bottom of the grid and click the down arrow of the combobox the autonumber field populates, as it should, and the master key value is also automatically entered in it's field, as it should be. The problem is that if the user decides not to select a value from the combobox at this point, and they try to delete t ...Show All
