VS - Program Doesn't Work Though Flash Player - When Click On Icon Of Program - Shows Error Message
Sep 30, 2010I 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.
CODE:
When I click on the icon of my program it shows the error message
CODE:

Visual Studio 2010 Created Program Doesn't Work On Windows7 64 Bit While Works Fine On Windows Xp
May 15, 2012I have one tool which we developed on visual studio 2010. there are basically two parts of my project, one is UI part which i wrote in VB and algorithm part which is in C++ on back end. When we compile C++ part it creates a .dll which is used by my front end VB program.
Now my problem is little weird since i am compiling and deploying this tool on windows xp machine but some of the users are using windows 7 64 bit machines and after running the program for about 5-10 minutes, it crashes on windows 7 with following error
Not enough storage is available to process this command and when i view details of that error, i get the following description.
See the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box.

i am completely clue less for this error since this program works fine on xp but doesn't work on windows 7.

PerformClick() Doesn't Work - How To Make It Work
Feb 2, 2011I have an application that requires data be entered, and after entering, a button is clicked to process that data. Clicking the button works just as it should--the data is processed properly. In constructing a test module, I provide a set of data values, followed by:
btnWhatever.PerformClick()
Nothing happens. I have used this syntax for years, and it has always worked flawlessly. I have triple checked everything else and isolated the problem to the failure of the PerformClick(). The PerformClick() is in a test subroutine that does nothing but fill textboxes and labels with default data, then calls the PerformClick() on the button to begin processing. Again, the button works fine, the data is entered as it should be, but the PerformClick() does not fire the click event.

.net - WInforms Combobox SelectionChangeCommitted Event Doesn't Always Change SelectedValue
Mar 23, 2012I have a WinForms app built with VB.Net in VS 2010, and I'm scratching my head over the following issue.I have a form with a combobox which gets bound to a datasource when the form is loaded:
With Me.cboCompany
.DataBindings.Clear()
.DataSource = Me.m_dsBidResults.Tables("Company")
.ValueMember = "company_id"
[code].....
This seems to work fine, as long as the user doesn't switch focus to some other control and then go back to the combobox. After switching focus, if the user then changes the combobox selection to the first item in the dropdown list (SelectedIndex = 0), the SelectionChangeCommitted event fires, but the SelectedValue remains set to the previously selected value. I've verified this by adding a message box in the above event handler, displaying SelectedIndex and SelectedValue side-by-side.
'add this to SelectionChangeCommitted event handler MsgBox(String.Format("Selected Index: {0}, Selected Value: {1}", cboCompany.SelectedIndex, cboCompany.SelectedValue))
This does NOT happen if the user changes SelectedIndex to anything other than 0; everything behaves as expected. I've verified that the table I'm binding to contains unique values for company_id and company_name.Do I need to use some other event to verify that the SelectedValue has actually changed?

Dll Doesn't Work On Any Other Computer
Mar 15, 2012Has anyone succeeded in creating a class library solution/project in VB.net VS2010 4.0 Net Framework for COM to run on WindowsXP Excel 2003. I created a dll which changed specific data in an excel worksheet. The dll worked just fine on the development computer but wont work on any other. I downloaded .NET 4 framework onto the target PCs and used RegAsm.exe to register both the .dll and .tlb files in the registry. That worked OK and the dll is visible as a reference in excel and can be ticked. The error message I get is RunTime Error -2147024894(80070002): Automation Error The System cannot find the file specified.
I also tried creating a Setup and Deploy project in the original development solution but this created just a vbproj setup file which the target PC cannot read (no VS installed), I hoped the project would create an EXE file I could use. Does anyone know any links that describe how to do this type of stuff as most links I have tried are either for Windows Forms projects are are way above my knowledge. Maybe someone out there has already succeeded with this sort of activity?
Express DLL Doesn't Work On Other PCs?
May 24, 2012I have Visual Studio 2010 Express Edition. I'm using it to evaluate functionality before purchasing the real thing, but I'm having trouble. I want to build a DLL that can be used on PCs other than my development PC, that I can call from VBScript.
I follow the hundreds of examples out on the intranet and things still don't work.I have built a simple HelloWorld DLL with a function that returns "Hello World".I've been through all the stuff about making the assembly COM visible, and the threads about Register for COM Interop checkbox missing. One person suggested editing the .vbproj file and adding a tag to turn on Regiser for COM Interop (which was not needed because it was already there).
Anyway, if I build my project and run my VBScript:
Set testdll = CreateObject("HelloWorld.Class1")
wscript.echo testdll.HelloWorld()
Everything works great. But....if I copy the DLL to another PC and register it with RegAsm, the VBScript fails with a "File not found" error on the CreateObject line of the VBScript.
In fact, if I unregister the DLL on my development PC and then register it with RegAsm, the VBScript now fails on my development PC. RegAsm said everything was okay and if I look in the registery using RegEdit, things look good, but it still doesn't work. The only way to get it to work again is to rebuild the DLL (which in turn, registers the DLL).
I'd like to be able to build a DLL which I can be registered and used on other PCs (without requiring those PCs to have Visual Studio 2010 EE and without requiring them to have the source and build the DLL).

I have tried almost every possible combination. Can someone please explain to me how to use this properly?ser is a datarow and GUID is a column with data type: unique indentifier (so a Sytem.Guid)
user.GUID.Equals(DBNull.Value) Then .GUID = System.Guid.NewGuid
I tried using above, IsDBNull(GUID), guid = dbnull.value, guid is dbnull.value etc etc I am just getting this error: The specified Cast is not valid.
