Yes, I'm stuck on using CredUIConfirmCredentials() with CredUIPromptForCredentials. Do you have a code sample on how to use both?

Hello,

I am trying to write code to open an explorer window and highlight a given file in that folder.

I am using ShellExecute(hwnd, "explore", fileName, NULL, path, SW_SHOW) to do this but it does not always seem to work.

Is there a better way to do this?

Thank you,

Andy Moore

So it works sometimes and not others, is that correct? When it does not work, what are the symptoms? What is ShellExecute()'s return value?

I have a app that runs on several PC.
My problem is that on some PC the text bmp's and rectangles are smaller.
The Monitors and PC are the same except for the graphic card.
I'm using MM_LOENGLISH and DeviceCaps are 96 on x and y on both PC's.
If I create a CRect top = -83, bottom = -38, left = 5, right = 95 and do a LPtoDP.
On one PC I get top = 54, bottom = 25, left = 3, right = 62 on the other
I get top = 80, bottom = 37, left = 5, right = 92?????
How do I make them all the same?

Please help!!!

Thanks in advance!

Automatically determing Save File Dialog filter type

Hello,

I know that this may sound like a trival question, but I am trying to automatically generate the filter string for the lpstrFilter member of the OPENFILEDIALOG structure.
I look up the file extension in the registry and attempt to build the filter string by concatenating the string from the registry with the extension. I have not had much luck doing this. Perhaps is there an easier approach to this?

Thank you,

Andy Moore

I guess basically what I am trying to do is if I have a file with a .zip extension, I want to call GetOpenFileName(&ofn) with the lpstrFilter set to filter only zip files, etc. I can look up HKCR/*.zip in the registry and get a string like "WinZip file". I am trying to generate the filter "WinZip Files (*.zip)\0*.zip\0".

I was wondering if there was already API functions that do this so I could avoid reinventing the wheel.

Thank you,

Can you not just concatenate those two strings together using strcpy()/strcat(), or with a CString object if you are using MFC?

I am using ATL and wsprintf to try to build this string, but so far with no success. I will have to do some more debugging I guess.

Thanks,

what extension strings from the registry ? from HKEY_CLASSES_ROOT ? darn, all of them ?

This is something that needs to be done manually, it's too application dependent to automate from something like the registry ( IMHO ).

anyway, it's usually a one time thing.

CEdit's Text Color when Disabled

Vladimir Georgiev16-Jul-04 7:06

Hi,

Does anyone know what is the way to change a CEdit's text color when the control is disabled?

I already implemented the reflected OnCtlColor, and it successfully changes the color when the control is enabled, but when disabled, the color becomes gray...

Thank you in advance.

This is normal (and expected) behavior. If you changed it to some other color, would the user know that the control was disabled, or would they try to interact with it and become frustrated when they couldn't?

I found a way to change the text color of a disabled CEdit.

1- You must derive a class from CEdit

2- Overwrite WindowProc and do the following:

LRESULT CMyEditBox::WindowProc(UINT message, WPARAM wParam, LPARAM lParam)
{
  if (message == WM_PAINT)
  {
      DWORD dwStyle = GetStyle();
      if (dwStyle & WS_DISABLED)
      {
          EnableWindow(TRUE); //Trick paint by temporarily enabling CEdit
          SetReadOnly(TRUE);  //Temporarily making CEdit read only

          LRESULT res = CEdit::WindowProc(message, wParam, lParam);

          SetRedraw(FALSE);

          if ((dwStyle&ES_READONLY) == 0) SetReadOnly(FALSE); //Restore READ ONLY style
          EnableWindow(FALSE); //Restore DISABLED style

          SetRedraw(TRUE);

          CRect rcClient;
          GetWindowRect(rcClient);
          ScreenToClient(rcClient);
          ValidateRect(rcClient);

          return res;
      }
  }

  return CEdit::WindowProc(message, wParam, lParam);
}

3- Overwrite CtlColor and change color when control is in read-only state (of course you can use a member variable instead of the read-only style to set disabled text color)

HBRUSH CMyEditBox::CtlColor(CDC* pDC, UINT nCtlColor)
{
  if (GetStyle() & ES_READONLY)
  {
    pDC->SetBkColor(GetSysColor(COLOR_3DFACE));
    pDC->SetTextColor(GetSysColor(COLOR_WINDOWTEXT));
    return GetSysColorBrush(COLOR_3DFACE);
  }

  return NULL;
}

Accessing Shared Resource from a Windows "Service"

Petrus Scott16-Jul-04 7:03

Petrus Scott

16-Jul-04 7:03

I have written a Windows "Service" that logs on using the "Local System" account and "Interact with Desktop" enabled. This Service is used to launch my application (via the CreateProcess API) when the computer is started. My application's data is stored on a shared network drive. The problem is "Local System" normally does not have access to network resources because it logs on with null creditials. This can be solved by adding the "shared resource" to the "NullSessionShares" registry key on the Server that owns the "shared resource".

This seems to work and my application is able to connect to the shared resource using the WNETAddConnection2 API. However, when my application tries to access a file on the shared resource (using the GetFileAttributes API), it returns an error code 5 (access denied). I checked the permission settings on the "Shared Drive" and "Everyone" has full access to this drive.

Any idea why I can't access this drive?

Thanks in advance,
Petrus

Maybe because the "Local System" can't be part of the any network group by definition let alone the "Everyone" group. What do you think?

What about creating an account for the service and give it the required permissions.

I'm not sure. I was reading "Microsoft Knowledge Base Artice 122702", which describs how to access a shared resource from a "Service", and it did not mention anything about adding/modifying accounts.

Perhaps so but further researching finds article 124184 which says:

Do not use the system account. Services, such as Scheduler, and custom applications can be configured using user-specific accounts. User-specific accounts provide user level security based on a specific account and associated password.

Accessing resources

Hello,

I am creating several modeless dialog boxes which have different style setups. The problem is CreateIndirect requires me to pass a handle to a LPCDLGTEMPLATE, which I don't really mind to create, but I was just wondering if it would be possible to access the pre-defined styles in the resources (just like MFC automatically does, when you create a modal dialog box) ?

Thank you very much for your time,

David

CDialog::Create() allows you to pass in the ID number of a dialog-box template resource. Is that what you are after?

How to receive outgoing message in MS Outlook, to read and change him if it is necessary.
If it is possible example without MFC please.
