Now the Modified code looks like this ...
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:

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.

I'm creating an MFC application.
I was provided by the manufacturer the following code in a .h file:
#ifdef DEFINE_GUID
// The GUID that is used to identify this device's interface
// {AF1B231E-1180-420b-8CB6-2ED2A53F9F92}
DEFINE_GUID(GUID_DEVINTERFACE_ALTGENERIC, 0xaf1b231e, 0x1180, 0x420b, 0x8c, 0xb6, 0x2e, 0xd2, 0xa5, 0x3f, 0x9f, 0x92);
#endif
I #include this .h file into my .cpp file.
This is the way I use it:
HDEVINFO hDeviceInfo;
hDeviceInfo = SetupDiGetClassDevs(
(LPGUID)&GUID_DEVINTERFACE_ALTGENERIC, NULL, NULL,
DIGCF_PRESENT | DIGCF_DEVICEINTERFACE);
I get the following errors:
alt.obj: error LNK2001: unresolved external symbol
_GUID_DEVINTERFACE_ALTGENERIC
c:\...exe: fatal error LNK1120: 1 unresolved externals.
Could someone tell me if I forgot to include a library or something....
Thanks.

Hi All,
We currently have a client-server application written in Win32 and we're in the process of trying to create a slimmed down version of the client software for the Pocket PC. Our application is a fair size, and uses a few in-house developed DLLs for drawing areas etc. We want to be able to use code contained in these .DLLs on our Pocket PC app to avoid multiple copies of the same code in two projects. We're using VS2003.NET for the Win32 development, and eVC 4.0 for the PPC stuff.
Has anyone been in these shoes before? How have they solved the problem?
I thought of creating a similar .DLL in my PPC application, and actually link in the sources files from the original.DLL while adding #ifdefs to the .DLL to include functions that I require, then compile them using the evC compiler, realizing that not all the calls we make the .DLLs will be available in the PPC environment. This could be quite messy, but would eliminate the maintenence issue.
I realize that some of the calls that the Windows .DLL will make, will not be available in the PPC Edition. We will need to address these individually I think.
Any suggestions? Thank you very much.
Mike

I was told a while back that to get a release build of a project, I click Build on the Build menu, and the project executable is found in the project's debug folder. Recently, I have been told that this build is not a release build, but a debug build. I am trying to get a release version of my program, so any help clarifying how to get a release build of a project would be nice.
Thanks
ps, I am using VS C++ 2005 Express

If you're using VS 2005:
you should be able to go to Project then properties then under configuration there's a place where you can select release or debug.
If you're using VS 6.0:
you should be able to go to Project then settings then you can select "Settings for:" either Debug or Release

I am using VS C++ 2005 Express (VS 2005), and I have found that properties window, but I am not sure which setting I need to change to get my project to build in release mode.
|
|
|
|
|
In VS 2003 and VS 2005, the active configuration under build can be selected in a dialog box activated from menu: Build --> Configuration Manager. Then change the value of Active Solution Configuration drop-down list to "Release".
In VS 6, use Build --> Set Active Configuration menu command.
After this rebuild your project.

Ok, I have changed the setting, Where is my executable built? Is it still in the project's debug folder? Thanks.

I am also getting errors from this process because the compiler says: "cannot open precompiled header: \release\test.pch"
I'm not sure what is going wrong. Any ideas? Thanks

In the projects Release folder.
|
|
|
|
|
The output file should be in the Release folder. In order to see or change this folder, open the project's properties dialog box and see the General --> Output Directory field.

Thanks. I am using the stdafx precompiled header, can I just transfer the .pch file from the debug to the release folder, or will that just end up creating a debug build instead of a release build?
Thanks
|
|
|
|
|
You will need to rebuild the whole application as "release", the precompile header will be redone in the release folder.

No, the PCH files are different in Debug and Release build. You should rebuild your application, and the PCH file will be created by the compiler.
