"hKey is expected to be assigned the registry handle."
but how as you did regKey.Close(); before *hKey = regKey.m_hKey; ??
Try
*hKey = regKey.Detach(); Remeber to call RegCloseKey() on the obtained handle once finished using it.

regKey.Close();
*hKey = regKey.m_hKey;
after closing the key the handle is invalid. You really shouldnt do that

Hi,
I have MFC dialog app and there is hosted WindowsFormsControl.
In MFC app it is declared as: CWinFormsControl<windowsformscontrollibrary1::usercontrol1> m_ctrl1;
Could somebody explain me why I can use it as a pointer: m_ctrl1->textBox1 and as a object: m_ctrl1.GetControl()
|
|
|
|
|
See CWinFormsControl is a template class.
template<class TManagedControl>
class CWinFormsControl : public CWnd
It has the -> operator overloaded to return TManagedControl.
inline TManagedControl^ operator->( ) const;
Then m_ctrl1->textBox1 will be TManagedControl->textbox. Also, GetControl() is a method of CWinformControl and it gets called when you use m_ctrl1.GetControl().
inline TManagedControl^ GetControl( ) const;

Hello,
Does anyone know how I might handle file inputs to my MFC program? So basically say windows is configured to launch my app for files with a given extension. What do I need to do in MFC so that I can get the path to the file and process it accordingly?
Many thanks,
Keith

All that you should do is check out HKEY_CLASSES_ROOT. And write the handler for command lines that are transferred to your app when opening the files.
|
|
|
|
|
|
See some of the suggested solutions here[^].
Broadly speaking the filename is passed to your application as a command line (text string) and you need to parse the string to find the filename and any optional parameters you may accept.
It's time for a new signature.

If your app was created via the MFC wizard, all of the pieces should already be in place. If not, check out EnableShellOpen() and RegisterShellFileTypes().

I am making a text editor in C++ and want it to save rtf an txt files. I have made a rich text box called richTextBox1, a toolstrip button called ToolStripButton1 and a save file dialog called saveFileDialog1. I need the save file dialog to save the contents of the rich text box when the tool strip button is clicked. Here is my code so far:
private: System::Void toolStripButton11_Click(System::Object^ sender, System::EventArgs^ e) {
saveFileDialog1->Filter="Text File|*.txt|Rich Text Document|*.rtf|All Files|*.*";
saveFileDialog1->Title="Save As";
this->saveFileDialog1->ShowDialog();
}
How do I make the dialog save the contents of the rich text box?

Hi,
the saveFileDialog is a dialog, it communicates with the user, it does not save a thing. Your code has to perform the necessary save actions upon the user's choices. So check for the dialog result, and if "OK", save the data yourself to the selected file.

You don't; the dialog merely gives the user the opportunity to select the destination file where the data will be saved. Your program then has to write the data into that file in the format relevant to the file type.

so how do I use the information returned from the dialog to save the file?
|
|
|
|
|
If ShowDialog() returns DialogResult.OK, use saveFileDialog1->FileName to open file file and write the contents.
|
|
|

The only information you have from the dialog is the file name and destination directory. From this you create the file and write your data to it, the dialog has no further influence on this process.

In addition to what's already been suggested, you might receive more help by posting to the correct forum.

if i'm using winforms with C++, do I post in winforms or C++??
|
|
|
|

I think you are fine here; although your program uses Winforms (Managed C++/CLI) your question relates to C++ and Windows API.

I'm using Visual C++ 6 on Windows XP. My program uses COlePropertyPage property pages. One of them has a List Control. When the user clicks a certain part of my List Control, a dialog box appears, and when the user is done with it, it disappears. However, if the dialog box is moved over part of my List Control, when the box is closed that part is erased and set to gray, the color of the underlying COlePropertyPage. I want the List Control to refresh itself when the dialog box disappears. The control will refresh itself if another window is placed on top and then removed. Of course, I don't want the user to have to do that! The List Control should refresh immediately when the dialog disappears.
I'm trying Invalidate(), UpdateWindow() and RedrawItems() one at a time and all three at once. It makes no difference. Actually, I note that my DrawItem function is called even without calling those repaint functions. Calling them just repeats the DrawItem function being called. However, the DrawItem call has no effect. Also I've tried setting the control to dirty with COlePropertyPage::SetControlStatus(). Nothing works.
Thanks for any help..

Try the SetImageList() method.

i try to use this code.
SHFILEINFO fi;
BOOL bReturn = FALSE;
HIMAGELIST himl = NULL;
ZeroMemory (&fi, sizeof (fi));
himl = (HIMAGELIST)SHGetFileInfo (filename, 0, &fi, sizeof (fi), SHGFI_ATTRIBUTES | SHGFI_SYSICONINDEX | SHGFI_SMALLICON);
bReturn = m_ImageListSmall.Attach (himl);
m_LIST.SetImageList (&m_ImageListSmall, LVSIL_SMALL);
I have found only same image showing in all column(what ever file is .doc or .pdf).
Can you guide me for this problem.

How many images are in the image list? When you add items to the list control, what index are you using for the image?
