• .NET Development C# Splash Screen while loading .NET assemblies

  Hi, is there any way how to display a splash screen with informations about loading .NET assemblies I am looking for something like is used in program RegToy ( http://greenfield.kn.googlepages.com/home ). This program is competely in .NET, so I hope there must be a solution... It is important that you activate the event handler as early as possible so you can catch assemblies getting loaded while your program initializes. That's why I put it as the first statement in the Main() method. At that point, your splash screen isn't yet ready to display the info. The workaround is to put the info you want to display in a Queue. Empty the queue with a timer in the splash screen form code. Yel ...Show All

• Windows Forms how to use function key to set focus

  Hi, I have a problem here is that I have a grid which I am keying in value. What I need to do is that how can i use the function key any will do be it F1 to F12 to focus on some other combo box. Not sure what you're asking, ProcessCmdKey isn't that special. Although it is pretty obscure. The message loop calls this virtual function when it gets a KeyDown message before dispatching it to the control that has the focus. In makes menu shortcuts work as well as special keys like Esc, Enter and Tab. You can use it for your own purposes too, as you do here. ...Show All

• .NET Development Interface property implementation question

  Hi Everyone, Apologies if this is not the right place for this question. Was just wondering if there is a sneaky way around an error implementing a property of an interface.

• Visual C++ Getting overriding inherited functions to work

  I am trying to override a function from a base class, but cannot get my program to use the derived class' fuction at runtime. To test it out, I wrote this: class ClassA { public : ClassA( void ); public : void talk() { cout << "CLASSA" ; } }; class ClassB : public ClassA { public : ClassB( void ); void talk() { cout << "CLASSB" ; } }; int main () { ClassA *B = &ClassB(); (*B).talk(); int i; cin >> i; } To my understanding, (*B).talk(); should result in ClassB's function being called, but when I run the program ClassA's is called.

• SQL Server SSIS Package Hangs in Data Flow, magically works after opening and closing components

  We're experiencing a problem where intermittently our SSIS packages will hang. There are no log errors or events in the event viewer. It will happen whether the package is executed from the SQL Job Agent or run from BIDs. When running from BIDs it appears to hang inside one of the data flows (several parallel pipes with sorts, merge joins etc...). It appears to hang in multiple pipes within the data flow component. The problem is reproducable, we just kill it and re-run, and it appears to hang in the same places. Now here's the odd thing: as we simply open and close some of the components in the pipe line after the place it hangs, a subsequent run will go further in the pipeline before hanging. If we open and close all the components af ...Show All
