Hi, My Program is supposed to run contineously so i need to concern about memory management with COM. Here is the scenario, I created a COM Object using CreateInstance() using that COM object i am creating another object using QueryInterface. Here is my question. 1. if i am releasing the first object which i got using CreateInstance, then subsequently the objects which are created using that will be removed from memory right? Since if i call release for object got using QI causing crash. But i am fine if i release the first object, but i am afraid this would lead to a memory leak issue. :( Kindly Advice! Thanks in advance:rose: -Ganesha

Hi, I am having a COM Component and i am accessing the com using VB client. In Com function i am using SysFreeString, i am calling a function inside COM DLL by passing a string argument from vbclient. After usage i am calling SysFreeString inside the com function. The above mentioned functionality works on several machines and fails(VB client crashes) in one machine. I removed the SysFreeString function call from the failing machine, and now it is fine. Can anyone tell why this happens so strangely ? Anyway we need to call SysFreeString to free up the memory. Kindly guide me! :( Advanced Thanks, Ganesha

1. Please ensure whether you have installed language packs. 2. Make us to understand your situation by providing some code snippets.

Thanks a lot

No it is not possible if you set your project _UNICODE in project settings, it will override _MBCS. But i am here in position of converting a large project into UNICODE SUPPORTED. Can i build that third party tool into a DLL and link them with my project ? Even though that also be defined _UNICODE. Any Idea ? Get me out of this difficulty!. :(( Thanks :rose:

Thanks a lot

Hi, Can we have our application as _UNICODE supported as well _MBCS supported? I am in middle of a robust project, where we are using some third party sources. if i set my project to _UNICODE supported then it forces all the places where i am handling strings are to be wchar, TCHAR etc., can i make the same in some files, since it forces to make changes in third party sources. To make UNICODE Supported i made changes like "In Project settings in preprocessor definitions i just added _UNICODE. Also set startup with wWinMainCRTStartup. Qns: Can i support both of them ? if so How ? Thanks in advance. :rose:

Thanks a lot

Actually i am sure, there is no manual for CImage, in MS Visual Studio though it is included. If so what header i need to include to proceed? Thanks for your response! :rose:

No, i tried but i couldn't. But i reached the goal in different way that, storing strings in a separate file and reading them from Unicode aware project and printing (SetWindowText) in a control. It works and it is fine. If you know how to paste the chinese text then please let me know~!

Thanks in advance

it is fine if i give p->SetWindowText(L"&Login");, Thanks a lot once again! :)

Thanks a lot

Hi, My Project is set to unicode aware, and it is fine. But when i am go for displaying a text in static control in run time, like CStatic *p = (CStatic *)GetDlgItem (IDC_STATIC1); p->SetWindowText ("&Login"); The text on static control should display the text as Login and the letter "L" should accompany a underline; It is working fine with MBCS projects but not with UNICODE, How to resolve this issue? Anyone please help, :confused:

Thanks in advance!!!!

Thank you very much for your valuable response! i will do as per your directions.!

Thanks a lot

Very simple! ;P But you have to explain the scenario clearly...I have done same the thing you have puzzled. Explain it again! :)
