Dialog Tray

Here is another issue that I have encountered, but I may have overlooked something, again. :rolleyes:

This program, listed below, is a dialog box that minimizes to the system tray, however, the icon that is listed in the resource does not appear. In the system tray a "i" in a dialog ballon is displayed. If another icon is added, and used, to the resource script a red circle with an x is displayed.

The really odd thing about this is that the dialog box does show the icon in the taskbar. :confused:

Since I have spent a lot of time starring at this code my eyes no longer see. Perhaps one of you programmers would be kind enough to correct this problem. ;)

Here is the application:
Dialog Tray.zip

I can't open the zip file. :(

I also can not download the zip file. In case you haven't already done so, be sure to include the source code to your program.

I do not understand? :confused: I am able to download the ZIP file, which contains the whole project.

I will have to get back to this. :rolleyes:

For the zip file name, don't use spaces, use underscores. I think that is the problem here.

The problem is being discussed in General Discussions right now. You can no longer upload zip files, but they are working on alternatives. For now, just upload your source code - you can still do that.

Ok.. I will try the underscore to see if that makes a difference. Here is the new link:

Dialog_Tray.zip

Hopefully this works for others. :) Again the link works on my machine. :confused:

The guy that knows what he's talking about above said that you can no longer upload .zip files. So just upload the source code and then we can get to your problem.

Wow... that makes things a little more complicated. :p Anyway, here is the code listed below:

Dialog Tray.cpp

Code:

Dialog Tray.h

Code:

---

#define WM_TRAYMESSAGE        (WM_USER+1)
#define ICONIDENT 0

BOOL CALLBACK DialogProc (HWND, UINT, WPARAM, LPARAM);
int NotifySysIcon (HWND,int,PSTR,DWORD);

NOTIFYICONDATA  Nicon;
HWND                        hWnd;
HINSTANCE                hInst;

char ToolTip[] = {"This is the tooltip"};

Resource.h

Code:

---

#define IDD_DIALOG                      101
#define IDI_ICON1                      104

Thanks for the help. :)

Please correct me if I am wrong, but your problem might lie in the NotifySysIcon() function. When your calling the LoadIcon() you are using the MAKEINTRESOURCE() macro with an int. I've always done MAKEINTRESOURCE(IDP_SOMEPIC). Unless you are setting the resource IDs as numbers, but #define 1 40003 wouldn't make a lot of sense to do.

Unless IconNum (or whatever the variouble is), is being passed 104? Okay I guess that wouldn't help you, I didn't notice you were passing IDI_ICON1 into the NotifySysIcon function.

Did you try testing the LoadIcon() call for errors?

Sorry for not getting to this right away. :o

Thanks for the interest tyouk. I have yet to debug this application because I am finding that while running windows XP the symbols do not seem to work. This bothers me. However, I will have to get to that.

Even though the NotifySysIcon procedure works great for a regular window, I really should remove the return value. The problem probably does exist in this procedure when it comes to the dialog box though.

Well after some brief investigation I have found that somehow my program is receiving the IDI_ASTERISK icon. I am not sure how but it is. Below is an update on the code:
