For instance, I read that visual basic .net didn't have operator overloads before, so wouldn't be able to use a types overloaded operators, if they aren't provided as normal methods too (Add, instead of operator+).

View 4 RepliesThe software I design is for Win XP and older versions such as Win 98, ME, 2000 etc. I currently use VB6 and Win XP for development and packaging, the problem I encounter is that if I use the deployment wizard in XP, the setup will only work on an XP machine and I need to copy all my source to an older machine and use the wizard again to create another setup file which will only work on the older operating systems. Is there a way to rectify this in VB6? If not, does the new VB account for this and be able to make a setup file for older operating systems as well as XP?

To the board: Lately I've been getting Runtime error 3447 ("The Jet VBA file (VBAJET.dll for 16-bit versions, or VBAJET32 for 32-bit versions) failed to initialize when called. Try reinstalling the application that returned the error") when attempting to open a certain program (not one that I designed, just downloaded and installed). I installed this program in January 2009, but this error began happening only this past July. someone else to information about the files vbajet32.dll and expsrv.dll. One site said that the problem was probably caused by the file expsrv.dll being absent, but I checked my System32 folder, and it's there. As far as I can tell, it has always been there (the computer was made in 2008, and as I said the program had always worked before). Vbajet32.dll is also there. I tried uninstalling and reinstalling the program, but error 3447 still occurs. I also tried uninstalling the program and installing an older version, but 3447 is still there.
I tried replacing expsrv.dll, thinking it might have been corrupt, but that didn't help, and I cannot register that dll anyway. I can't figure this thing out. Both of the files are there, and I didn't change any settings or anything anywhere between last January and this July. By the way, I am on Vista.
visual basic.net is case insensitive so it allows the coder to write without caring or remembering the casing of variables. it also relieves from the 'undeclared variable' errors if you use the variable in another case than the one used in declaration. The fact that its line termination is a line feed makes it even more readable unlike C# or c++ that need good care in the casing and contineous war with following up with the {}, matching them and figuring out which is for which.my question is what are the advantages of c# over vb knowing that both get compiled to MSIL so there is almost no performance difference between the two languages?

View 1 RepliesI'm creating an application software. It has many features, which is in the base version of the software. And people could buy my software (which will be enough for most of them since it had all the common features needed) and use it. But some of them might need additional features to this version.So, I can add new features to the base version of my product and provide them a custom or extended version.
But my question is, how can I effectively manage these versions of the software while updating (or upgrading with new features which are common to all of them)

In the above example F1, F2, F3, F4 & F5 are the features available common for all editions of my software.Whereas, A1, A2, A3 & A4 are the additional features added based on customer's request.

So far, I have always run applications within the IDE, using Debug Mode.If I publish an application will I have to add code to repaint Picture Box graphics?In the IDE, my Picture Box graphics never get disturbed by running some other application or minimizing my forms.

I want to be able to drag data from one DGV to another. When the drag is completed, I want the backcolor of the cell that the data was taken from to change to red. I will add a "trash" icon that will accept a drag and drop from the 2nd DGV to remove the data from its respective cell. Finally, when the cell is trashed, the corresponding cell from the first DGV will return to it's normal backcolor. My application is going to be used to schedule clients with employees for a home health care business. The reason I want all of this is so the user has a visual aid to show them that times have been used already to avoid double staffing. i also have to figure out how make all of this unique to each client when flipping through the DGV/binding source.

View 1 RepliesI've gone through about 16 hours and two packs of cigarettes trying to figure this out. First a little background. I was using 6.0 up until 2004 when I went to prison. I'm out now, and trying to relearn the trade, using VS 2005. I'm currently porting some 6.0 code from another project, SpyCast Webcam Studio, into VB 8.0. It's disheartening, to say the least. None of the old built-in subs/functions work anymore, so I have to scour the forums to relearn each and every function.The section I'm doing now takes a snapshot from the webcam (Video API --> PictureBox --> Save as Jpeg), then upens the file to upload it to the server via HTTP POST. I've been using this code in SpyCast for years with no trouble, but I spent many hours trying to piece together the right code to open the binary file to read its contents. I pieced together two methods I found around the forums, one using FileStream() though the code I found wasn't for binary files, even though it said it was, so that code doesn't really work. Method two uses Microsoft.VisualBasic.FileOpen() and works better.
Here's the kicker. By the time I run through the rest of the rigamarole of uploading the file, by the time I read it on the webserver, it's *slightly* corrupted. It's a valid Jpeg, no errors, but the picture looks like when I use to watch the Playboy Channel when I was a kid scrambled with weird colors and whatnot. [code] Each "chunk" is basically one "line" of the file. It looks like a single LineInput() return is the text between two carriage returns. Am I correct? I tested this with a flat text file, and it looks true. However, That one input line returns the text or data with the carriage returns *stripped*! ***?!? =( Fine, I have no problem adding my own vbCrLf to each LineInput(), if I were opening text. but this's binary. A character could be Chr(10) or Chr(13), both of which are removed from the original file contents.So I could very well need to use something other than LineInput(), but I haven't found any other examples on the web using this method.

I'm using the following code to kill a program: Dim pProcess() As Process = System.Diagnostics.Process.GetProcessesByName("myprogram.exe")
For Each p As Process In pProcess p.Kill() Next
At one point it's running twice and the above code kills em all including the one currently running, resulting in an access error. Is there any way to say, kill the older myprogram.exe only. Compare both of them and see which one was executed first and terminate this one, keeping the later one running.

I have some work I need to do with some older ActiveX controls. When I install the controls (outside of Visual Studio) I get an error message:
Quote:
The procedure entry point SRWriteStringLocalCmd could not be located in the dynamic link library SankyoMP.dll
Doing a little research I get a whole bunch of different answers. Microsoft says that this is because it was written for an older version of Windows (2000 or before, I am using XP) and to contact the vendor. The vendor is out of business.
Does anybody know of a way to install and use this older ActiveX control in VB.net/Visual Studio 2005?
I need to delete older bkf files in a directory, only leaving the newest 20.
No, I can not just delete older than x days because there can be more than one backup file per day and some times it may be 2-3 days before a backup file appears.
Got a dll from a supplier that I need to call. His declaration is Declaration with Microsoft Visual Basic: [code]Now, the Sting * 20 is clearly not VB.NET, and sure enough it crashes when run - "Attempt to read or write in protected memory" and that leads me to think that there is something with that string definition - or possibly the I_Ref definition which hasn't been defined as fixed length.I've tried <VBFixedString(20)> when defining O_Err, but I have a feeling that it might not be enough when the function declaration is like that (not specifically fixed length). I cannot figure out how to specify this correctly.As a small hmmmm, the above is pasted directly from the suppliers documentation, but that't will never work, as there is a "," missing after I_Range as long... Clearly not something he has pasted from a working program.
