• Visual C++ Can I write to MemoryStream?

  In .NET we can save data to MemoryStream, can we do this in Visual C++( not using Managed C++) Regards There is no way to access managed stuff from the unmanaged world directly. So i.e. exposing an interface or function that can be accessed directly. You have to use at least some mixed code or you have to expose a class from the managed world via COM. ...Show All

• Visual C++ VC++ 2005 doesnt compile, when non-startup project header is changed...

  I have five projects in my solution. First four creates static lib and the fifth is exe file that uses those libs. The fifth project is set as startup and dependent to others. Whatever file (cpp, h) is changed, compilation occurres after F5 (build project) is pressed. I can also change something in cpp of the dependent project and it is also compiled. The problem are any changes in header files of dependent projects. VS just saves them, but writes: " ========== Build: 0 succeeded, 0 failed, 5 up-to-date, 0 skipped ==========" to the output window and compiles nothing.

• Visual Basic reading a string from the right until...

  I thought this would be simple to figure out (and perhaps it is), but I’m not finding it. I want to extract the last part of a string and save it in a variable. The string lengths are never the same, but there are consistent separators, as below: home\work\school\neighbor I need to save “neighbor” in a variable. My idea was to simply read the string from right to left and stop at the first instance of “\” but I am having trouble finding the proper way to do this. BTW, I’m using VB 2005 express Sure that can be done.... There are numerous ways of doing this. Heres a function which ...Show All

• Windows Forms controls not rendering on the form

Has anyone ever encountered such a thing If yes, then what maybe the cause of it Thanks Nitin That means that there was an error when loading the control into the designer. If you resize the control larger, the error should be a part of the image (the white rectangle with a red X). I am afraid that I cannot be more specific without a repro scenario. ...Show All
