Re: How to set the initial directory of the CFileDialog to be 'My Computer'?

Set the initial directory to ::{20D04FE0-3AEA-1069-A2D8-08002B30309D}

CFileDialog f(TRUE);
f.m_ofn.lpstrInitialDir = L"::{20D04FE0-3AEA-1069-A2D8-08002B30309D}";
f.DoModal();

I truly appreciate your help.

Another thing I wonder is that whether this is documented by Microsoft. I'm testing it on previous version of Windows (NT, 9x). Will it be changed in the future?

Thanks so much.

That CLSID has resolved to 'My Computer' since Windows 95. I see no reason for it to change in the future.

Question on SOAP with Attachments/DIME/Web Services

15-Dec-05 10:09

I am not sure of Vista, but it should work the same in 98, 2000, XP and 2003.

I am developing a web service application using ASP.NET and the MS WSE (Web Service Enhancements). On the server side, there is an asmx file running on IIS wich is able to recieve a SOAP message with a DIME attachment (e.g. an *.gif).
Now I am developing a client that can send those messages with a DIME attachment.
Here's the basic method I am trying to implement:

// ***********
SoapContext *reqC = RequestSoapContext::Current;
DimeAttachment *dimeAttach = new DimeAttachment(
"image/gif", TypeFormat::MediaType,
"C:\\temp\\IMG_3621.jpg");

reqC->Attachments->Add(dimeAttach); //System.NullReferenceException???
// ************

When I am trying to build the programme, the process breaks with an exception, claiming there was a "System.NullReferenceException" (Object reference not set to an instance of an object)in the last line of code posted above.
What does that mean?
The above method is taken from a MSDN example wich is also quoted here on codeproject.com (http://www.codeproject.com/soap/DimeTest.asp). In the examples it is used as a server method (the server sends a SOAP message with a DIME attachment on client request), but I need it as a client method so I changed the SoapContext into a "RequestSoapContext" instead of a "ResponseSoapContext".
I did include all the necessary namespaces and headers, the compiler accepts all commands without throwing any errors, the error appears during build/debug.
The examples are in C# but I am not familiar with it so I need to be doing it in C++.

Thank you in advance for any hints!

P.S: I am not a native english speaker- please excuse my faults.

CFileDialog allows bad filenames

Hi,

I'm using CFileDialog and have setup the extensions etc and it seems to work correctly.
The only problem is that if a type a non existent filename into the filename text box and select open CFileDialog exits (DoModal returns IDOK).

Surely I don't have to check that the file from calling GetPathName() exists?

Cheers,
Ally

Why not use OFN_FILEMUSTEXIST?

How to simulate clicks on toolbar buttons?

Hi,

I tried both TB_PRESSBUTTON and WM_LBUTTONDOWN, but I failed. Do you have any ideas to solve this problem?

Thanks in advance.

do you need a visual feedback ?

Toolbar buttons are COMMANDS, so , you could ( never tried it ) do a SendMessage with the appropriate command ID.

I would do a PostMessage myself...

Hi,

I tried to send the WM_COMMAND to my toolbar, it worked. But it failed when I sent that message to the toolbar of the Open File Dialog (CFileDialog). Here is my code:

<br />
hwndToolBar = ::FindWindowEx(hwndParent, NULL, _T("ToolbarWindow32"), NULL);<br />
::SendMessage(hwndToolBar, WM_COMMAND, MAKEWPARAM((WORD)40961, CN_COMMAND), NULL); // 40961 is the ID of the "Up One Level" button.<br />

I didn't know why it failed. Please help me. What I need is programmatically clicking on the "Up One Level" button.

Thanks in advance.

Are you sure the FindWindowEx returns an HWND? Perhaps it returns NULL.

Cyrus Dang15-Dec-05 9:12

15-Dec-05 9:12

It works now. The problem is that when I send the message. It wouldn't work in WM_INITDIALOG and WM_NOTIFY (code CDN_INITDONE). It worked well in WM_NOTIFY (code CDN_SELCHANGE and probably others but I've not tested yet!)

Thanks for helping.

Nish Nishant15-Dec-05 9:28

That's cool, but to be safe, you should always check if FindWindow(Ex) succeeds before using the HWND.

What's this? Do you mean the monitor's model number?

In multiple display monitor environment, windows assigns each monitor a monitor number 1,2,3...so on. I want to retrive that info for all the available display monitors.
Thanks.

How about EnumDisplayDevices()?

He wants to know the default monitor in a multiple monitor setup.
