To access Private Key from certificate use CryptImportKey() function and you can look into the MSDN sample code for encrypting the data http://msdn.microsoft.com/en-us/library/aa382006(VS.85).aspx[^]

yes i am able to launch a gui (made using mfc) which displays in columns the "Issued By", "Issued To" and email address of all the certificates in MYSTORE. When I click on any of the rows, I am able to display the corresponding certificate by using the Display() command. Shall I email you my code so far? I am using VS2005.
thanks

yeah i got the data to sign now, but im stuck with verifying the data, i googled it and couldn't find a satisfactory solution for it. seems to have something to do with capicom being made for java and all so the way its handling or data is different than c++ (ascii vs unicode) so im stuck there now lol. thanks for the concern though

I am having a Drop down list box which contains values as A,B,W,X,Y,Z. Only for the first time, the Dropdown list having the name corresponding to the key pressed gets displayed. But for the next key strokes, the corresponding name is not displayed.How to display the value corresponding to the key strokes?

Thanks,

Are you wanting to know: 1) how to display a message box, or 2) how to detect a mouse click in the client area of an SDI view?

All processes automatically inherit the environment block of its parent process. If the process is created with the CreateProcess Function[^] then you can pass a pointer to a new environment block in the lpEnvironment argument.

Calling the SetEnvironmentVariable() with the new value will change the current process' environment variable.

Yaa it's working fine but here i have a doubt the variable is set at system level or user level ?
If it sets at system level the setting of environment will fail when i run my application in power user or guest user

What do you think about menu of that program? each program has a option on its menu(Save) you can find it ID of save option and then send your query to it.

No its not.
If you click on the current program(for example IE) you can see File->Save,it has a id for example IF_FILE_SAVE for Save or ID_FILE_CLOSE for Exit you need to get a handle to this menu of this program(or for other programs (you can use of FindWindow or Enumwindow for get a hwnd to that program and then you can use of that handle on the ::GetMenu()) then you can use of GetSubMenu for a handle to the pop up menu and then you can send your request.

What about keybd_event(VK_CONTROL | 0x53)?

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
