• Visual Studio Best Practice: Complex Visualizer Deployment, Debugging.

  We are working on a pretty complex SDK. It comes with a couple of visualizers, but they are COMPLEX. That means they will depend on a significant number of additional third party libraries installed. Like Infragistics, like possibly some others. We talk about visualizing, for example, complex object graphs. What are the suggested best practices for that I do not like to put the third party libraries into the visualizer folder, simply for possible versioning problems. I also do not like to install them in the GAC out of pure necessity - i mean, a visualizer should not really install anything there. I guess things would be easy if I only ...Show All

• Visual C++ reference counting problem

  Hello everyone. I have been developing two ActiveX components. One is written in VC++ 6 and the other is written in VB6SP6. The VB component is the container of the VC++ component. The idea is to use the VB component as a browser plugin. My problem is when I shout the internet explorer off. I get an assertion on line 52 in cmdtarg.cpp. The line is ASSERT(m_dwRef<=1); and m_dwRef is equal to 2. I have been reading some articles that sais that internet explorer holds a reference of the activex document for a while, or until is closed. So, i may be doing something wrong. If some one knows about this problem, please, let me ...Show All

• .NET Development Bizarre GC behavior (while testing a WeakDictionary)

  I am encountering a bizarre GC behavior while testing a dictionary that I have designed. The designed dictionary is a WeakDictionary. That is basically a Dictionary where all values are kept through a WeakReference. The WeakDictionary does not prevent the values from being collected if they are not rooted elsewhere. Here below is the NUnit code that I am using to test the WeakDictionary. As you can see there are lines with REQUIRED. If those lines are omitted then the last assertion fails at index itemCount - 1 . Exactly like if the internal loop reference where holding a reference to the object outside there loop scope. If I am correct ( ...Show All

• Visual Studio Linked Solution. Does this work in 2005

  One of the biggest headaches for us, is creating Applications consisting of many solutions.  The normal recommendation from Microsoft is to put everything in one solution but this is not always ideal. The problem we have is the Debug/Release functionality.  If you build a solution the assemblies are placed in target directories. These are based on the release type. When you reference an assembly which version should be referenced What we need is some kind of support for VS switching referenced DLL's when the solution switches release type. Has VS05 made any changes in this area   What is required is an "Add Solution" which pu ...Show All

• Visual Studio VSS: % in filename

  I have added to a VSS project, a file which contains a % char in the filename.  For example: "Is_Old_New_65%Line.vi".  When I try to Check-out the same file, VSS complains with the error: "Is_Old_New_65%Line.vi is not a valid SourceSafe syntax".  Looks like VSS is treating the % as a control character, and rejects the filename.  Since VSS was able to ADD the file with the % character, it should also be able to Check-out/Check-in the same file. Has anyone else run into the same problem   Any work-arounds, besides deleting the old version, and Re-ADDing the new version, which defeats the concept of versi ...Show All

• SQL Server SMSEE no longer launches, after SBO is installed...

  Well, that's what happened to me anyway. I was using the SQL Server Management Studio (November CTP) succesfully since two months ago. Yesterday I found the SQL Server Books Online for 2005, and, thinking nothing could go wrong, I installed them. Since that very moment, SMSEE does not work anymore. Task Manager tells me "smssee.exe" starts, but then disappears immediately, in less than a second. Any idea why could this happen And, most importantly, how can I get SMSEE to work again, short of removing/reinstalling Thanks for your help! - Izhido An update... It's getting worse.

• Windows Forms Is creating form objects and disposing them better or using Activator.CreateInstance()?

  I'm building an MDI application, and when user clicks various menus I want to load the child forms only if it is not loaded previously. I came up with two versions of methods to create the child form when menu is clicked. In the first version the calling method creates a Form instance, and in second version it sends Form's type. Both version work, but can experts explain which is better private void ShowChild( Form formToShow) { foreach ( Form form in MdiChildren) { if (form.GetType() == formToShow.GetType()) { form.Activate(); form.WindowState = FormWindowState .Normal; fo ...Show All
