Use a CString variable here, instead of that member variable

I already tried it but i got same problem...

CString str;<br />
<br />
static TCHAR BASED_CODE szFilter[] = "Windows Setup file (*.pdf;*.xml)|*.pdf;*.xml||";<br />
<br />
CFileDialog oFileDlg(TRUE,"pdf","",OFN_FILEMUSTEXIST|OFN_NOCHANGEDIR, szFilter);<br />
oFileDlg.m_ofn.lpstrTitle = "Select the Installable Application";<br />
<br />
<br />
if(oFileDlg.DoModal() == IDOK)<br />
{<br />
str = oFileDlg.GetPathName();<br />
<br />
AfxMessageBox(str);<br />
}
This should work fine.

Is there any thing else you have kept after the message box? If not there has to be no problem at all.

It has to do with how you've defined _WIN32_WINNT, most likely as 0x0500. The OPENFILENAME structure used by CFileDialog is the smaller sized one. So, use GetOpenFileName() instead.

Hi,
Sorry if the question was not clear

Hello,
all menu items have an identifier, you must to use them to find which menu item has been klicked!
Is that what you mean?

If you pass the TPM_RETURNCMD flag to TrackPopupMenu(), then the return value indicates what was selected. If you don't use that flag, your window will get a WM_COMMAND message just as if the menu bar had been used.

If I only know the DIO device is at port 280.
How can I access it? (read / write the pins)
NO API is available.
Please help!
Any relative information is welcome.
Thanks!

Assuming you're running some windows environment, you'll need a device driver for your device. You're not allowed to access the hardware from user mode.
Since you clearly state that "NO API is available", I assume you don't have a driver for your device and you've possibly made the device yourself.
If you bought the device it should be shipped with a device driver, unless it registers itself as a common device such as a COM port, in which case you can use ::CreateFile(), ::ReadFile(), ::WriteFile(), ::CloseHandle() and such to access it.
If you don't know anything else about the device besides the I/O port: give it up, there's no way to guess.
However, if you know how the device works and how to communicate with it at low level, you can develop a device driver of your own.
This way is quite hard, but if you'd like to have a go for it, start by reading Toby Opfermans article serie about device driver development here[^].
Hope this helps

The device is together with the PC on delivery.
And it works in the debug mode.
eg. type "-o 280 F1" as a command
I just dont know how to access it using cpp.
So, I think I can use ::CreateFile(), ::ReadFile(), ::WriteFile(), ::CloseHandle() to access it, right?
More question, using ::CreateFile, should I use "port280" as the file name?
Thanks very much!

If you open a device with ::CreateFile(), you have to provide the device name as argument to the function, e.g. "COM1" when opening communications port 1.
You have to find out what your device is called before you can access it through these methods. Look for settings in the Device Manager.
It's not possible for anyone else to know what your device is called in your machine. Perhaps if you mentioned what kind of device it is someone could tell you how the device usually presents itself and how to communicate with it.

Hi,
I'd like to save the Z order of all windows. In fact, i'm working on a HideAll windows and ShowAll.
That's why i'd like to save this z-order to get the windows restaured in the same order.
thanks

Hi everyone,
it's possible to set on creation a specific RGB-Value as Backgroundcolor for a CFormView.
Is it also possible to change the backgroundcolor at runtime? for example by clicking a button?
If i change the brush like this m_bgrBrush.CreateSolidBrush(RGB(255,255,255)); it crashes during the click-event
Thanks 
|
|

|

You can use of a variable on m_bgrBrush.CreateSolidBrush(yourcolor);
