Yes.

-------------------------------

If you are looking to register a com dll from your application - Simplest way could be to run RegSvr32.exe in silent mode (parameter -s) through ShellExecute()

   Yes, most COM registration takes place using some kind of coding...

   As for HOW, well, you need to add your object's/interface's information into the Registry. I would also suggest that you also register your Proxy/Stub (of an out-of-proc COM Server), and also register your Type Library (if you are IDispatch-based, see see LoadTypeLibEx(...)). This greatly simplifies installation issues.

   Peace!

Or execute <server name>.exe /RegServer if it's an EXE-server.

CreateFile fails to open temp file

Hi
I have a program asociated with a file extension, when I open the file via Outlook, it creates a temp file in:

Documents and Settings/sebastian/Local Settings/Temporary Internet Files/OLK37/file.mio

My app receives the path, but CreateFile fails with error 123: File not exist

The file exist, but that is a system/hidden folder.

Why is failing to open the file??

This is my call to create file:

<br />
<br />
	HANDLE hFile = CreateFile(param, <br />
		                  GENERIC_READ | GENERIC_WRITE, <br />
			          0,<br />
			          NULL,<br />
			          OPEN_EXISTING,<br />
			          FILE_ATTRIBUTE_NORMAL,<br />
				  NULL);<br />
<br />

Thanks in advance Big Grin | :-D

Error 123 is not a File Not Found error - there is something wrong with the path you are passing to CreateFile(...).

Peace!

Try and open a cmd console to check if the path is really correct. Sometimes folders have another name as the one displayed.
Can you open the file with Notepad at the given location ?

LCD MATRIX CONTROL OF MR WILSON

I have developed a similar control with
1. No bitmap require to carry with the project (low application load)
2. Let the characters of the control to be decided by the system while putting static control on dialog.
User need not to specify no of character per control, it will be calculated.

3. Just change the scale to change the size (accordingly no of character will be increased/decrased)
4. = operator to assign the text (easy to use)
5. support of new line (\n) character. eg. "abcd\nefg" it will
show
abcd
efg
(in two line control)

6 Non-ASC-II non-printable character view (eg. 0x1 has got smiley face image)

I want to upload it free, How Do I ?

Is there a VC++ function to send messages between PC's in LAN? What is the command to send messages between PC's in LAN?
THere are 5 PC's in the LAN. Only PC1 has direct connection to internet. The rest of the PC's connect through PC1 with the help of a proxy server. All these PC's belong to the same WORKGROUP.
