never seen this, but instead of restarting the whole IDE, what about just rebuild all ?

The IDE itself locks up and has to be killed with the Task Manager.

Anyone knows how to set the description text for a Windows Service? (the text in the second column of the Services MMC window).
Tnx
|
|
|
|

If your program only runs on Windows 2000 or later, use ChangeServiceConfig2 with the SERVICE_CONFIG_DESCRIPTION if the service is already installed.
Otherwise, you will need to edit/add a registry entry under your service.
Hive = HKEY_LOCAL_MACHINE
Key = SYSTEM\CurrentControlSet\Services\<servicename>
Value = Description
Type = REG_SZ
Supply the text you want for the descripiton.
|
|
|
|
|
|
Here's how I do it.
SERVICE_DESCRIPTION Descr = {(LPSTR)GetServiceDescription()};
ChangeServiceConfig2(schService, SERVICE_CONFIG_DESCRIPTION, &Descr);

Hi
Im in a fix regarding accessing the flexgrid control of my dialog.
Im calling my dll(MFC) through an exe. In the dll there is a dialog that contains the FlexGrid. on calling of the dll the dialog box gets called. now i want to populate the grid with some data but im unable to access the flexgrid. On accessing the method of the grid it is showing Assertion error.
I know there are gurus in VC++ and hope you will assist me or give me any pointers.

How can I detect when the ALT key is pressed and no other key is pressed? I wanted to change my cursor when the ALT is pressed. So i wanted to know which message is sent in this case.
Thanks

Try with WM_SYSKEYDOWN

It works only if i press a key followed by ALT. I want an event which fires when i press just the ALT key .

Is GetAsyncKeyState() of any help?

Yes i am using it get the state of the ALT key but the point is I want to change my cursor as soon as the user presses the ALT key so for that i would require an event being fired or Currently i am using a timer which uses GetAsyncKeyState() to get the state and then i change the app cursor.
Thanks

Could you show me how and where you have written the code.

What about the WM_CHAR message?

Hi Everybody!

Hello everybody,
I'm looking for a client library to get and delete mails from an imap server.
Now, I use the IP Works library and the delete of the mails is too long (30 sec).
Thanks

On one of my dialogs I have about 70 check boxes which when checked toggle the associated bool value in an array (one bool for every check box).
Rather than create 70 check boxes on the dialog and also then write (copy) the handling code for each check box, is there an easy way to do this?
|
|
|
|
|
I would do it like that: you keep an array of CButton (I think this is the class that handle check boxes messages), then in OnInitDialog, I will instantiate this array and create the check boxes:
BOOL CyourDlg::OnInitDialog()<br />
{<br />
m_pCheckBoxesArray = new CButton[m_ChckBoxCount];<br />
for (int i=0;i<ChckBoxCount;i++)<br />
m_pCheckBoxesArray[i].Create(......);<br />
}
In the Create function, you will need to pass the Id of the control and its position. For the Id, edit the ressource file and use consecutive Id's so you can just do something like that:
for (int i=0;i<ChckBoxCount;i++)<br />
m_pCheckBoxesArray[i].Create(.., IDC_FIRSTCHCKBOX+i ,....);<br />
In the ressource file, you can do something like that:
#define IDC_FIRSTCHCKBOX 10000<br />
#define IDC_LASTCHCKBOX 10070
Then you can use the ON_CONTROL_RANGE macro instead of ON_COMMAND to map the notification messages of all your check boxes (take a look in the MSDN).
Hope this helps

thanks, I'll give this a try,

If I were you I would decide whether I need so much of them and they are all needed at once. Notice that this way gives you 2^about70 different combinations. Is every combination allowed and does make sense? I would reprogram this interface.

I have downloaded a sample program from this web-site to read data from a com-port.
When I compile and run everything is fine.
When I edit the code, and then change it back to it's original, and run the program, every second character that is recieved by the comport is false. ie.
vv.v.v.v.v.v.v.v.v.v.v.v.v.v. or 00°0°0°0°0°0°0°0°0, I can't show all the wierd characters as they are not on the keyboard.
but if I only send 1 or 2 of the same characters, then it is ok, ie.
aabbccddefghij and so on
Does anyone know what the problem might be? I'm using Visual c++ 6
I think it might be using Unicode, but still don't understand why it'll do it if I change it back to the original code. For it to work again, I have to run a fresh copy of the source code.
Thanks heaps!
