I am really confused! My program doesn't work if I don't have Visual Studio here in my PC. To test it I have uninstalled Visual Studio. But my program doesn't work though Flash Player is present there (I have used Flash animation in the first form).
To be more sure about it I have installed Flash. But it's not working! That means the Flash animation file (.swf) is not making a problem! It needs support from Visual Studio to start. Doesn't it mean that some files are not attached with a setup file as a result it needs Visual Studio to run? Let me tell you how I create a setup file of my program.

View 3 RepliesI am using Visual Studio 2005 for coding. I am doing an exercise where I have to create a data lookup program. The program is to illustrate the concepts of using a database to look up information based on user input. The program allows a user to input two search criteria for a product search. The program then displays each individual search result, or record that meets the search criteria in a message box. I am not getting the message box and I don't know why. No errors are present during compiling so I have no indication as to where the problem is.

View 1 RepliesI have code that's working beautifully on my development machine, but when deployed to the server is throwing null reference exception. So, I can't step through the code, but I've pinned down the culprit. But now I am puzzled.[code]In the code above persons is a dictionary of custom class, and certs is of IEnumerable type. Now here's the quandary.. The first line that sets the label returns False, so certs is not null. But the second line throws an null reference exception.

I got a serious problem. Though I have made my program newly it shows error. I have used 1280,1024 animation only for first form then used 1280,1024 image for every form. Today I was checking then it was showing me error message for 19th & 20th form. If I use On Error Resume Next then it shows error for another form ; if I use same code there in the menu item I mean so that I can get rid of error when I click to show a form it shows another error. First error message is "InvalidOperationException was unhandeled An error occurred creating the form. See Exception.InnerException for details. The error is parameter is not valid." and second error is "OutofMemoryException was unhandled Exception of type 'System.OutOfMemoryException' was thrown". I have noticed it that it doesnt show error message for those form which have few labels and text boxes. It shows error message for those forms which have 1 menu bar, 2 picture boxes(one is 1280,1024 & another is 250,456), 2 group boxes, 40 labels, 3 combo boxes, 38 text boxes & three buttons. Please help me I need to get rid of this problem. Does it mean that I cant use unlimited control there in my form?

View 6 RepliesI have created a com dll in Visual Studio 2010, vb.net. The dll is supposed to compile in the framework 3.5 for X86 processor. Should run anywhere right? I reference this from an Access application using vba. All works well on my development machine. I must also say that the project references an eBay sdk dll called ebay.service.dll. This file supports converting the .net commands into the appropriate soap commands to communicate with eBay.
All this works well on the development machine when compiled. The files in the bin/debug folder are eBayListing.dll, eBayListing.tlb, and eBay.Service.dll. I can reference eBayListing.dll from Access and everything works well on the development machine. On the laptop I registered the eBayListing.dll and eBayService.dll using the visual studio regasm at: C:WindowsMicrosoft.NETFrameworkv2.0.50727RegAsm.exe. Both files appear to register as I get the registered message from regasm. I run this as administrator.
When I try to set the reference from the Access application in the VBA references I can only see the reference to the file as it was on my development machine. I can tell because it has the path the the bindebug file. I don't see the version of the dll supposedly registered on the laptop. The file obviously isn't there so I browse to the file on the laptop that is theoretically registered, but get an error.

I'm doing a simple calculator program calculating Pennies, Nickels, Dimes and Quarters. I made a Try-Catch statement so that if the user enters letters into the text boxes, they get an error message. However, if the user leaves one field blank, the error message still pops up. What's the code so that I can get Visual Basic to recognize that an empty field is the same as 0 so that that message doesn't pop up? [Code]. What do I need to add to it to get that Error Message to stop showing when the user doesn't enter a value into one of the text boxes?
