I changed my code to use Image class.
I still have the same problem.
I open a image file. then try to save it in png format.
Save fuction returns "Win32Error" status.
GdiplusStartup is successful.
What may be wrong?

Can you show your code did you attach hbitmap handle to CImage class?

Another thing I noted is that if I give only the filename.jpg or png, it saves successfully, but if I give the whole path it fails with Win32Error.
|
|
|

When you use of filename.jpg it uses of current directory so I think your problem is of path.

Then probably either the path doesn't exist or you don't have sufficient rights to write to the path.

I have given "D:\\123\\123.png" as the path. The path exists and I have full control of the folder.

If you step into the Save method in the debugger, where is the error occurring?

In the CBitmap Save call. It returns Win32Error.
|
|
|
|
|
There shouldn't be a CBitmap::Save call....it should be a Gdiplus::Bitmap::Save call.

How did you try like this:
m_Image.Save(_T("c:\\123\\image.jpg"));

Can you show your code for save and show how did you attach bithamp handle?

Hi,
doesn't Save need a second parameter to tell which format to use (JPG/PNG/...)?
Luc Pattyn [Forum Guidelines] [My Articles]
I use ListBoxes for line-oriented text, and PictureBoxes for pictures, not drawings.

|

|
|
It has a default argument.
If I dont pass, it will save it in a format identified by extension.
|
|
|
|
|
does that mean you got it to work? if so, how?
|
|
|
|
|
Ya I got it to work. But it still doesn't work the way it should.
I set the required path as current directory and then I call Save with only filename as the parameter (no path prefixed, since it still doesn't work that way.)

I typed "hyperlink" into the search box at the top of codeproject, and found several articles doing what you want - and with hand cursors.
I'd pick http://www.codeproject.com/KB/miscctrl/hyperlink.aspx[^], as it's one of the very first articles on codeproject.
Or you can just handle WM_SETCURSOR/OnSetCursor if your code is almost complete.

Create a message handler function OnSetCursor(CWnd* pWnd, UINT nHitTest, UINT message) for the message WM_SETCURSOR
Declare a HCURSOR variable in your class
HCURSOR mLinkCursor = NULL;
In the OnInitDialog function, add the below block
if(mLinkCursor == NULL)
{
CString winDir;
GetWindowsDirectory(winDir.GetBuffer(MAX_PATH), MAX_PATH);
winDir.ReleaseBuffer();
winDir += _T("\\WINHLP32.exe");
HMODULE hModule = LoadLibrary(lpzWinDir);
if (hModule)
{
HCURSOR mHandCursor = ::LoadCursor(hModule, MAKEINTRESOURCE(106));
if (mHandCursor)
mLinkCursor = CopyCursor(mHandCursor );
}
FreeLibrary(hModule);
}
Now, you update the added OnSetCursor function as
bool myClass::OnSetCursor(CWnd* pWnd, UINT nHitTest, UINT message)
{
// Note: Here IDC_HYPERLINK is nothing but your control Id
// that should get the hand cursor when mouse moves over it.
// Update this to your ctrl Id
if((pWnd->GetDlgCtrlID() == IDC_HYPERLINK) && (mLinkCursor != NULL))
{
::SetCursor(mLinkCursor );
return TRUE;
}
return CDialog::OnSetCursor(pWnd, nHitTest, message);
}
I found this in one of the forums. This should work.
Let me know if you face any problem.

Messages of the form 'sparta1.exe': Loaded 'C:\Windows\System32\clbcatq.dll', No symbols loaded. indicate DLLs foir which no debug information can be found.
Messages of the form First-chance exception at 0x00000000 in sparta1.exe: 0xC0000005: Access violation reading location 0x00000000. indicate some part of your code accessing an invalid memory location - I suspect dereferencing a NULL pointer (or possibly callling a virtual method on a NULL pointer) in this case - difficult to say more without code.
Step through the code in the debugger - the debugger will tell you when the access violation occurs...

Point 2:
That should be coming - this is a bad spelling mistake that I won't explain. And wait until you're home before you research why.
