• Visual Basic Problem with VB after installing VS6 Enterpise Edition

  Hello, I have recently purchased and installed Visual Studio 6 Enterprise Edition on my Windows XP Home machine.  Everything went fairly smoothly, until I tried launching Visual Basic 6.  As soon as I double-click the shortcut I immediately get a "Visual Basic has encountered a problem and needs to close." error.  What makes this situation even more frustrating is that all the other VS6 components (C++, FoxPro, etc) launch and work without a problem.  The only thing that is giving me trouble is VB. I have since both un-installed and re-installed and tried to repair the installation.  Regrettably, whatever I seem to try leads to the same result - all components of VS6 run well except for VB6.  If need be ...Show All

• .NET Development Could not load file or assembly 'vcWebCore' or one of its dependencies. The system cannot find the file specified.

  All, I have a web project that references a strong-name DLL which contains a HttpModule, it is called vcWebCore.dll. The DLL is registered in GAC using the gacutil.exe and everything looks fine.

• Windows Forms Datagridview formatting inside a tab control

  I've been trying to figure this out for some time. I've searched for answers for people doing similar things but I am having no luck. I havegot a datagridView, populated from a database, inside of a tab control. It's 4 tabs in. I wrote some code to change the formatting of rows that contain a certain value in a certain column. This code puts a strikethough and changes the font to red. If I use this code on a form outside of a tab control, I have no problem just executing it in the Load event of the form and then on the sort event of the control. I can't get the control to format properly when inside the tab control. I've already tried adding the code to every event I can think of including form load, TabPage Enter, Tab Page Leave, go ...Show All

• SQL Server SQL Management Studio from desktop PC connecting but no acccess to service functions

  I have a new and virtually full installation of SQL 2005 Developer with SP1 installed (named instance), on a Windows 2003 standard server, which also has a default instance of SQL 2000 SP4 installed. I have the browser service running also enabled TCP/IP for remote connections via configuration manager. All services are currently using LocalSystem.

• .NET Development DllRegisterServer entry point was not found error

  I am using VB in VS2005 Pro to create a dll for distribution. The dll is created in the bin directory but when I try and register it with regsvr32 I get: DllRegisterServer entry point was not found. This file can not be registered. Depends shows missing dwmapi.dll What is the fix for this I'm not sure exactly what you're doing, but VB in VS 2005 is VB.NET, and you can't create Win32 COM Dlls with that, which is why regsvr32 won't find DllRegisterServer. If you are building an assembly for COM interop it's regasm you should be using. ...Show All

• Visual Basic Adding multiple numbers to textbox

  Hey guys, I'm looking to add multiple numbers to a textbox. Like for example, say I have three buttons button1.text = 1, button2.text = 2, and button3.text=3. What I'm wondering is how to get all those numbers in the textbox without having to erase the previous number I clicked on. For example: If I press button1 I want the textbox to show 1, then if I decide to press button 3, I want the textbox to show 13. the sender object will be one of the three buttons because this      Handles Button1.Click, Button2.Click, Button3.Click its means thes prucedur will be called when one the events hass been raised Button1[object]  Click[event]     ' Button1.Click  &n ...Show All
