QueryAssemblyInfo ****s my brain if I remove the two comment (lines) gacfilepath will have the right path; if I don't gacfilepath will be null; Assembly executingasm = Assembly.GetExecutingAssembly(); string currentassemblyname = executingasm.Location; string asmname = executingasm.GetName().ToString(); //int untilat = asmname.IndexOf(", PublicKeyToken="); //asmname = asmname.Remove(untilat, asmname.Length-untilat); string gacfilepath = Fusionhelper.QueryAssemblyInfo(asmname); Any idea guys?

Windows Hook Library

Windows Hook Library The WindowsHookLib is a single library to hook the mouse, keyboard and the clipboard system wide. WindowsHookLib library is written in C# and there for it uses Common Language Runtime (CLR). This means that the library can be referenced from various projects in Dot Net. The mouse and keyboard hooks are low level so you can use the Handled property of the MouseEventArgs or the KeyboardEventArgs to prevent the windows messages be passed to the other applications. Note you need to use the dll file not the classes in your projects; otherwise they might not work correctly. Link: />http://www.code2point.com/Project.aspx?proj=4

Hi Guys... Hope someone can help me out with a problem in delphi programming. First of all i'm coding in delphi since around 3 month. I want to describe my prob a little bit more... I'm using windows 7 x64. In win7 and also in win vista you can add program links to the task bar. But you can only do this when the string "IsShortcut" is written in the windows registry. When this string exists you have on your desktop some "freeky" arrows on your links. So i made a little app to write and delete this string to the registry. For now so good. But you only see the changes take effect when you log off and on again. Or you do a complete system restart. And theres my problem. I kn…

Hey all, Something else than those C++ and x86 asm programming stuff topics. Let's hope someone knows soemthing. I've been attempting to code an interrupt driven usart connection between an AVR chip board and the PC. (the PC is sending the data) However it seems that when an byte is recieved it keeps giving interrupts even when the buffer is read. (which should stop that according to the datasheet) Interrupt code which is properly triggered when recieving a byte but just keeps interrruptingand spamming my terminal: Serial_Recieve: ;store incoming bytes in r24,UDR out UDR, r24 reti Am I missing something here. Afaik I am initing the serial connecti…

right, so yesterday night i had a native vsc++ 2008 project display a dialogbox using the DialogBox(...) functon. worked perfectly fine. i then went to bed, and when i got up this morning, the exact same DialogBox call would just return -1 and fail. I then did some further testing: 1) Creating a dialogbox with a list view on it always fails 2) creating a dialogbox with NO list view on it always succeeds. sometimes the dialog will get display correctly, sometimes the form-background is missing and some dialog items are floating around freely.it always takes up 100% cpu power. 3) creating a new,clean project with a dialog but no list view, it works in the beginning, but aft…

hi, so i have been messing with native GUI programming in msvs2008 recently and lots and lots of problems & questions arose... Most of them were exterminated by a quick google search. This one is a little persistent, though: I have a class, myclass. The user can create multiple instances of that class. Every class instance has its own instance of a dialog box, which can be displayed at the same time. How can i now link a class instance to a dialog box? ie, if the dialog boxes CALLBACK routine is called, how can i know which class instances dialog box send the message? deep0

hi all, this little problem is killing me: char data[256]; mystruct* mystructptr; //copy some stuff into the data buffer int the buffer "data",there are 12 junk bytes, but then there is a mystruct struct. i need to point to that struct... way #1: mystructptr = (mystruct*)(data+12); this works just fine, mystructptr points to the address of "data" + 12. this, however, doesnt work: mystructptr = (mystructptr*)data; mystructptr = (mystruct*)(mystructptr + 12); or mystructptr = (mystructptr + 12) or mystructptr += 12; the data buffer gets increased by ~0x400 bytes, not 12... i really cant see why #2 wouldnt work.
