The only examples I have found are for VS C++ 6.0; e.g. Circle, Button, CIRC1/2/3 etc.
Are they any articles/tutorials for VS .Net as the Wizards hav gone on .Net
Cheers,

Is it possible to use the DeviceIoControl() function to send commands directly to the driver for a COM port?
I am developing a time sensitive serial port application where I periodically need to change the parity of my serial data. Calls to Get_Comm_State() & Set_Comm_State() to update the parity are taking too long. I observed (using a serial port monitor) that these get and set methods do alot of unnessecary things like seting the baud rate etc.
It would be nice if I could use the DeviceIoControl function along with the IOCTL_SERIAL_SET_LINE_CONTROL command (or similar) to quickly change the parity from within my application. Am I living in a fantasy world or is this a possibility?
Many thanks

Hi all
I have an application window, which is created as
a child to the IE window(i'am using the Findwindow and SetParent API's
to set it as child to IE) which is working fine.
My problem is when ever the child window is minimized, it is displayed
in minimized state with in the IE window, but my requirement is to display
it on the TaskBar.
I tried to set the style of the window to WS_EX_APPWINDOW but it works
only for unowned windows.
is there any way to make it appear on the taskbar.
thanks and regards

Hi ,

You should not be redistributing DLLs from your Windows XP system directory. Windows 2000's Windows File Protection should actually be kicking in when you attempt to do this. Instead, you should use the Merge Modules that match your Visual Studio service pack version. Download for SP5[^], download for SP6[^]. Note that there are known issues[^] in these merge modules.
You need to be very careful about which file versions you copy to which operating systems, and how you get them there. The merge modules include (mostly) correct instructions for which files to install on which systems. If you're not using Windows Installer you may want to look for redistributable package installers which you can run from within your own installer. Getting it wrong can screw up your customer's whole system ('DLL Hell').
I would strongly recommend avoiding the Visual Basic 'Package and Deployment Wizard' (which I refer to as the 'Package and Destroy Wizard'). This tool regularly picks up DLLs from the Windows system directory rather than the Redist directory it's supposed to (default location: C:\Program Files\Microsoft Visual Studio\VB98\Wizards\PDWizard\Redist) and also picks up many components that should not be redistributed. It can be used safely but is very hard to do so.
These days I generally use Visual Studio .NET 2003's setup projects to distribute applications, using the merge modules for distributing components I depend on, modified as instructed by the InstallSite page I linked to earlier.

You may use the standard registry operation functions to open and read data.
I am not sure if these are correct, I do not have MSDN installed on this machine, but I have worked a lot on dealing with windows Registry. I believe the following are the functions.
<br />
RegOpenKeyEx<br />
RegQueryValyeEx<br />
RegSetValueEx<br />
I would suggest you open the key, read value, and write it into a text file in BINARY MODE.
Hope this helps. If you need more information about how to do this, just write back a word.

Use this instead:
ShellExecute(0, "open", "RegEdit.exe", "/e D:\\write1.reg \"HKEY_CURRENT_USER\\Software\\Microsoft\\Windows NT\"", NULL, SW_SHOW);

ShellExecute( 0, TEXT( "open" ), "RegEdit.exe", "/e d:\\write1.reg \"HKEY_CURRENT_USER\\Software\\Microsoft\\Windows NT\"", NULL, SW_SHOW);<br />
Only difference is that I've wrapped the registry key in quotes, if you dont RegEdit will try and treat the key name as part of the export filename

Is there a difference between using the WinInet function HttpSendRequest() asychronously and calling the function on a new thread?
I'm currently using HttpSendRequest() on a separate thread but it still seems to be blocking the winsock 'keepalives' that are sent between our client program and server programs.

And ?? What's the problem ? 
Also, when you post code, use the code tags just above the emoticons
|
|
|
|
|
1. use <pre></pre> tags to post blocs of code.
2. use < and > when you have to display < and > in your code (in if, for, while, #include statements).
3. ask for a specific question ; "could any one help me [...] Help please" is not a question.
4. target the code that don't work and post only that code instead of 2 full big code files.
5. read the forum guidelines[^].
and at last 6. use the [Modify] link at the bottom of your post to edit it instead of repost the same thing twice...
sincerely,

The String class in .NET, used by most of the controls returns Unicode strings.
I want to do some IO operations using the FILE* type. But fopen() accept only
char* arguments for the file name. Is there a way to solve this problem because
byte conversion can cause data loss?
Thanks a lot!
