I use function _gcvt() for convert the double value to string such as:
y = 0.01;
_gcvt(y,10,buffer);
MessageBox(buffer);
My problem is that the MessageBox will show "1.e-002".
How to do if want the string "0.01" after finish this function.

|

you could try doing a sprintf.
y = 0.01;
sprintf ( buffer, "%f", y );
|
|
|
|
|
Use
sprintf(buffer, "%f8.2", y); instead.

or see here

double y = 1230.01;<br />
CString strxx;<br />
strxx.Format("%lf", y );<br />

Hi,
The below code for cfiledialog is have some problem. the problem is when i
press open many times the file dialog box opens ,but sometimes ( at any time ) when file dialog is open and if i press some starting character to select particular file ,the whole application closes automatically..
myclass::OnOpen() {
CFileDialog dlg(TRUE);
Sleep(50);
if (dlg.DoModal() == IDOK) {
l_strFileName = dlg.GetPathName();
MessageBox(l_strFileName);
filepath2 = (char *) (LPCTSTR) l_strFileName;
m_select.ShowWindow(SW_HIDE);
m_start.ShowWindow(SW_SHOW);
m_ed.SetWindowText(l_strFileName);
} }

What's this for? A gratuitous Sleep() is usually an indication of something gone wrong.

Exactly what steps are you taking to reproduce the problem? Does it happen with every folder, or one in particular? What character are you typing? Is Enter/Return clicked? Does the same thing happen with GetOpenFileName()?

You've got problems elsewhere that are manifesting at the point in which you are using CFileDialog. This code should run 20+ times with no troubles:
CFileDialog dlg(TRUE);
if (dlg.DoModal() == IDOK)
AfxMessageBox(dlg.GetPathName());

Just an FYI since I don't think these issues are causing this problem (at least not directly) ...
1) Manjunath S wrote: Sleep(50);
Chances are very high that if you are calling Sleep, something is wrong with your design. This is almost always the case when done in GUI code (as is the case here).
2) Manjunath S wrote: filepath2 = (char *) (LPCTSTR) l_strFileName;
LPCTSTR is defined as (const TCHAR*). Aside from the fact that the cast above won't work properly in a UNICODE build, it isn't want you want anyway. You aren't showing what you use filepath2 for, but I'm guessing you will either want it as a CString itself, a List/Array of CStrings, or don't need it at all.

Hi,
1.I deleted sleep
2.I need to pass filepath2 as a char* to a function in DLL.
Now the Modified code looks like this ...
void Upload::OnSelect()
{
CFileDialog upload(FALSE);
if(upload.DoModal() == IDOK) {
l_strFileName2 = upload.GetPathName();
MessageBox(l_strFileName2);
/* where filepath3 is a global char* variable */
filepath3 = (char *) (LPCTSTR) l_strFileName2;
m_start.ShowWindow(SW_SHOW);
m_select.ShowWindow(SW_HIDE);
m_edt.SetWindowText(l_strFileName2);
}
}
The above code problem is CfileDialog and whole application closes automatically (once in 18-20 times of Onselect is clicked) .The application closes when i try to select filename in filedialog using keyboard charater(i.e filename first character) )..
Thanking You

And the DLL method doesn't take a const char*? If that is the case, what you are doing is still a problem. You are casting away the const on a CString object's private data (which you have no control over). Basically, if the CString object decides to clean up or allocate a bigger block, your pointer is out in the weeds. Try this:
char filepath3[_MAX_PATH] = {0};<br />
void Upload::OnSelect()<br />
{<br />
CFileDialog upload(FALSE);<br />
<br />
if(upload.DoModal() == IDOK) <br />
{<br />
l_strFileName2 = upload.GetPathName();<br />
MessageBox(l_strFileName2);<br />
<br />
strncpy(filepath3, l_strFileName2, _MAX_PATH);<br />
m_edt.SetWindowText(l_strFileName2);<br />
}<br />
}

Are there any functions available to set the language used for menus/dialogs once a MUI is installed?
The user would manually configure this via: control panel -> regional & language options -> languages tab
Microsoft calls this the UI language and documents functions (GetSystemDefaultUILanguage, GetUserDefaultUILanguage) to get the value, but nothing to set it:
www.microsoft.com/globaldev/reference/localetable.mspx
Thanks for any help

Hi,
I have created MFC SDI application. I see the title as "Untitled App" after execution. How to change it to the desired one?
I don't see any caption in the form's properties. I have changed the caption
in AboutDialog, but that doesn't help to change to caption of the application.
Thank you.

Turn off the FWS_ADDTOTITLE style in the CFrameWnd
|
|
|
|
|
Note that removing the FWS_ADDTOTITLE style (do in in pre-creation of the CMainFrm window) will only prevent the "untitled" part from appearing - it prevents the document name from going into the title bar.
There is a string in the string table that is used to create the static portion of the caption used in the title bar. Try changing that string to the desired text.
Peace!

Hi,
with reference to the article by "Zoran M. Todorovic"--"A Visual Framework:Controls,tabs and splitters",I have created an application with the help of this article.There are 2 tabs on my main window(SDI based MFC-VC++ dot Net-2003 app),and I would like to switch between the two using the main menu,some option like-"Switch:tab1,tab2 etc".If the user clicks on Switch,he has the option of selecting either tab1 or tab-2.
The corresponding tab should come to focus on selection from the menu.
I would be extremely grateful if any one could help me on this.
Thank You very much.

I am coding this using VC++ 2003. I noticed that my intellisense gives me the expected options when I drop the declaration into a VC++ 6.0 project and "dot" the member variable. Not sure if that helps.

Disregard the question. I discovered my folly.
I thought I had already checked nIndex in a trace but it turns out it was right where one would expect to find the problem. nIndex was the issue.
Sorry about the post.
