• Visual Basic check textbox lenght

  How do I check textbox lenght in vb.net 2005 this wont work me .MyTextbox.Lenght < 13 then messagebox.show("test") Well, I see two problems with this code. One, you mispelled 'length'. Two, you don't have the word 'if' at the start. Perhaps you have those in your code and not in your example, the fact that you don't define 'this won't work' makes it hard for me to tell. However, if you make those two changes, it will most certainly work. ...Show All

• Windows Forms Redraw perf problems with custom controls

  When making large controls that can draw quite a lot of data at once (when scrolling up and down) is it best to move over to DirectX because come of my clients are getting out of memory errors when they do large searches (see the link for a screen shot of the control). I can’t see t being a problem with my code as i have gone through the entire thing tweaking it, as far as I can tell its when the users scroll up and down a lot. This causes the control to redraw what it needs and get rid of everything that no longer needs to be drawn, however when they scroll up and down the garbage collector cant free up the resources fast enough, I’m th ...Show All

• Visual Studio Team System VSTS Architect vs. VSTS Developer

  With he proposed changes in MSDN subscriptions and Visual Studio licensing, I now have to make a decision between VSTS Architect and VSTS Developer. As I understand, MSDN Universal subscribers will have a choice - they can either go for VSTS Architect and VSTS Developer. I believe that I need both architecture and development tools. Which out of two should I go for The information was interesting but too high-level to be really useful or answer the questions I feel most developers have. I hope you folks will be releasing something with a bit of meat on it like a feature by feature breakdown of what is included in each edition in t ...Show All

• SQL Server Using Sql Express databases with Windows Forms applications

  Hello all, I would like my newly converted to .NET 2.0 Windows Forms application to use an Sql Express database instead of MSDE. Previously, development was done on the default SQL Server instance using the full SQL Server 7.0. When deployed, MSDE was used with a named instance. The connection string in the application settings needed to be modified as part of the deployment. Now I've converted to .NET 2.0 and to Sql Server 2005, and/or Sql Express. What I'd really like to do now is have a project within my solution that, when built, creates the database by running scripts, and deploys that database to the output directory of the exec ...Show All

• Visual C# MS ReportViewer 2.0 Control Print Bug/Issue

  The first attempt to print a report by clicking the print button on the MS report viewer icon does not print. Subsequent clicks will print the report! This is happening on all computers the application is deployed to. I look at the print queue and I see that the job is spooled and I also get the taskbar notification. I have tested numerous other applications and all print on first attempt. Is this a known problem or is there a workaround Thanks in advance, Ashkan As i can see in the other thread, this are two known bugs by Microsoft.

• Visual Studio Copy Task - Illegal characters in path

  When I look at the output from this task everything makes sense except the error.  Running the copy command from the command line works properly and there are no obvious security ACL issues.  Any thoughts on what might be triggering the "illegal characters in path" error Task "Copy": Copying file from "C:\Projects\Common\trunk\bin\debug\*.*" to "R:\Common\2.0\45\debug\*.*".

• Visual C# The new IntelliSense feature is fantastic!

  The new IntelliSense feature is the answer to a prayer. As much as I like C#, I always wished for an IDE option that would make it a little more like VB in one particular way: variable name case insensitivity. Under VB, if I declare a variable called “ MyVar ” I can subsequently type it as “ myvar ” and VB will automatically correct the casing as soon as I hit the space bar or enter key. Not only do I not have to go to the trouble of holding down the shift key, I also get immediate feedback as to whether I spelled the variable name correctly. That always seemed like a huge advantage in terms of improving everyday productivity. By making ...Show All

• Visual C++ Linker error when calling legacy DLL methods with CString arguments

  I am developing a C++ application in Visual Studio 2005 that needs to call methods in a legacy MFC DLL that exports a class with CString arguments in its public methods. The legacy DLL is compiled in Visual Studio 6 and I don't have the source files for it so I have to use it as it is. My problem is that I cannot link with the DLL. When I call one of the methods having a CString argument I get this linker error: error LNK2019: unresolved external symbol "__declspec(dllimport) public: static bool __cdecl DFUEngine::IsDFUFileValid(class ATL::CStringT<wchar_t,class StrTraitMFC_DLL<wchar_t,class ATL::ChTraitsCRT<wchar_t> & ...Show All
