Hi, I have created a program e.g. test.exe by C#.net and I want to associate file extension (eg .tst) with the test.exe in the window registry. But I found that most commercial program specifying file type in window registry by CLSID, (so the file type may be opened by the program for the dll specifid by the CLSID) which is only for dll. I have only an exe and I can specify opening the file type in the open subKey in the registry. But how can I specify the file type with a dll(CLSID) which in my case I dont have ? or how can I convert my exe into dll so I can open the file type by the dll ? Thanks

Hi, I use the following code to open a folder1 with window explorer and with file1 inside select. But the problem is that if the desktop has a file with the same filename as file1, it will select the desktop file instead of selecting the right file1 in the folder1 ! Why ? Process p = new Process(); p.StartInfo.Filename = file1; p.StartInfo.WorkingDirectory = folder1Path; p.StartInfo.Arguments = "/Select," + file1; p.Start(); Thanks

Thanks for your answer ! But what is the weak reference technique that you have mentioned ?

Hi, I have written a complex program in c#.net. After the program is running for a long time by user interactions, its memory usage will increase to the limit of the system, then error will occur. How can the program alert the user that the memory usage is nearly close to its limit before it goes into error ? I have tried memory garbage collection but the program is too complex that garbage collection cannot clean up the memory usage effectively. Thanks

Hi, I got a problem in focus at a treeNode of a treeView on a panel by program. Even I set treeNode1.Focus(), the node still can't get focus. There is no problem where the treeView is just on the form without the panel. How to solve it ? Thanks

Hi, I want to store the location of a file in C# program, but the file may be moved into another location. So besides using the File System Watcher, can I store other information of the file instead of the location, so that the shell or window can recognize the file by the stored info and give me the new location information ? Thanks

Hi, I associate a multi-level contextMenu to a control by using contextMenuStrip. I associates right-click events for each toolStripMenuItem, so there are many events registered and it seems quite rather inefficiency. Are there any methods similiar to the Toolbar that only one single click event is needed for all buttons in the toolbar ? Thanks
