a question about #import and _com_error

Hey everybody!

I am looking for a while a way to disable _com_errors being thrown through COM, and only get the HRESULT (S_OK or something else...) with no luck (I don't want to catch the _com_error).

From what I understood it is an attribute to the #import directive, but I can't really find one that causes that action.

So, is there a way to #import a dll and the prevent _com_error, so I can simply check the HRESULT alone?

Thanks!

First, Thanks for your help! Smile | :)

but that attribute forces BSTR and VARIANT instead of _bstr_t and _variant_t.
It still throws _com_errors... Confused | :confused:

Hey,
I had a little mistake when before I wrote the other thread.

It Works! Smile | :)

, cause it simply disables the smart pointers...

But with it, it takes the _bstr_t and _variant_t and and all the other good things of smart pointer... Frown | :(

Oh well, at least I know what to do!!! Smile | :)

Thanks again!

Linker Error

I've developed a project in VC++ 2005. It works in Release mode. When I compile this project in Debug mode, I got many errors which states,

error LNK2019: unresolved external symbol "__declspec(dllimport) public: void __thiscall dtAnim::CharacterWrapper::SetGroundClamp(class dtCore::Scene *,float)" (__imp_?SetGroundClamp@CharacterWrapper@dtAnim@@QAEXPAVScene@dtCore@@M@Z) referenced in function "public: __thiscall dtAI::AICharacter::AICharacter(class dtCore::Scene *,class dtAI::Waypoint const *,class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> > const &,unsigned int)" (??0AICharacter@dtAI@@QAE@PAVScene@dtCore@@PBVWaypoint@1@ABV?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@I@Z)

You probably forgot to link to a library file in the project options for the debug mode. Where does the class CharacterWrapper come from ?

It's from an external tool. I've included all the libraries mentioned in the guidelines for this tool. How can I find out which library is missing and where do I link that particular library?

Open the project settings for the release version and check in the linker category. There should be somewhere an option "Additional Dependecies" in the "Input" category (well, that depends on which IDE you are using). Check if the debug mode uses the same libraries as the release mode.

Loading Bitmap to a dialog with no background

I have loaded a bitmap to a dialog.
But that bitmap contains white background and it looks odd in the dialog.
I need to match bitmaps background with dialogs menu (grey) color.
How to do this?

The technical word for Making bitmap background invisible is MASKING...
if ur using white color as Bitmap background then

Use below function to change it to backGround color
ColorTo( RGB(white),RGB(BkGroundColor));

Search in an MSDN for this concept and also follow the code

// Create a Bitmap object from an image file
Bitmap myBitmap = new Bitmap("Grapes.gif");

// Draw myBitmap to the screen
e.Graphics.DrawImage(
myBitmap,
0,
0,
myBitmap.Width,
myBitmap.Height);

// Get the color of a background pixel
Color backColor = myBitmap.GetPixel(1, 1);

// Make backColor transparent for myBitmap
myBitmap.MakeTransparent(backColor);

// Draw the transparent bitmap to the screen
e.Graphics.DrawImage(
myBitmap,
myBitmap.Width,
0,
myBitmap.Width,
myBitmap.Height);

I am writing a structure of 20 bytes in to a file. Whenever I run the application I want to capture the last set written into the file. I used SeektoEnd () but of no use. How can I capture the last set (all 20 bytes of the structure) from the file?

i think i you open that in binary type, you should be able to do CFile::Seek(-20, CFile::end);
