Hi, I am invoking my mail client using following piece of code. The code opens the mail client having a subject and a file attached with it. Note: Following piece of code is written in java, i hope the same follows for vc also. String strLicensePath = "c:\\rohit.txt"; try { Runtime.getRuntime().exec( new String[] {"rundll32", "url.dll,FileProtocolHandler", "mailto:" + "&subject=" + "TEST_STRING" + "&attachment=" + "\""+ strLicensePath + "\""} ); } catch (Exception ex) { ex.printStackTrace(); } The above code works fine on my machine having "Microsoft Outlook 2000 SP-3" installed. But gives following error on machine having Microsoft Outlook 2002 installed: "The command line argument is not valid. Verify the switch you are using." Also, the problem is coming in some of other machines also. Am I using wrong switches, i.e. arguments?? Or is there any alternative way to achieve the same. Please comment.

Dear All, I am developing a dialog based application using MFC VC++ Version 6.0 for Windows 2000. The application consists of a TabControl derived from CTabCtrl Class having three tab pages in it. Also, the tabControl has Apply, Cancel , Ok button. My query is how to communicate between the tabpages data and OK,Apply button ??

Dear All, I am developing an application for Windows 2000 NTFS file systems using VC++ MFC version 6.0. I need to query whether "Norton antiviral" is installed on a system or not. We know that Norton Antivirus runs as a service. So to find its existence I suppose, I should query whether the service for Norton exists of not in the system. So my query is that "Is there any API provided to know existence of a service given its name. (In this case, navapscv is the name of the service, also we know its rest of parameters like display nameless)" Or, is there any alternate way to accomplish the same task? Please let me know if you need further clarification in this regards, Regards, Rohit

:confused:Dear All, I am developing an dialog based application using MFC VC++ Version 6.0 for Windows 2000. The application needs to perform certain tasks immediately before logging off /shutdown of the system respectively. For detecting logoff/shutdown i have handled WM_ENDSESSION event. OnEndSession call informs the CWnd object whether the session is actually ending and this event is fired for both logoff as well as for shutdown. I need to detect the difference between log off event and shutdown event because I need to perform seperate functions on logoff and shutdown. Am I capturing the right event for handling this issue ? Also if possible please suggest any alternate way to perform the same. Waiting for your reply. Regards, Rohit

Dear All, I am developing an application using MFC VC++ Version 6.0 for Windows 2000 OS in which I am running an inf file using ShellExecute api to install my driver. Following is the small piece of code used to install the driver: //////////////////////////////////////////////// void InstallSys() { char EZinf[1048]; strcpy(EZinf,"c:\\mydriver.inf"); //path of my driver char EZlpParameters[uSize]= "setupapi,InstallHinfSection DefaultInstall 132 "; strcat(EZlpParameters,EZinf); ShellExecute(NULL, "open", "rundll32.exe",EZlpParameters, NULL, SW_HIDE); } //////////////////////////////////////////////// The code is working fine and installing the driver. When I run the application, the application ,it calls Installsys() to install the driver and this displays a progress bar window titled "copying file" window and installs the driver. I donot want this popup window to be displayed during my installation due to some reason. I have used SW_HIDE option in ShellExecute function but still the popup window is still being displayed. Do I need to make some changes in the inf file?? Or I need to use the Inf SetUp File APIs (ie. SetupInstallFile or InstallHinfSection API) Please suggest some way to hide the dialog box and at same time installing the driver. The installation part of mydirverinf is as: ///////////////////////////////// ;; ;; Default install sections ;; [DefaultInstall] OptionDesc = %FileSpyServiceDesc% CopyFiles = FileSpy.DriverFiles, FileSpy.UserFiles [SourceDisksNames] 1 = %Disk1% [SourceDisksFiles] filespy.exe = 1 EZOn.sys = 1 [DefaultInstall.Services] AddService = %FileSpyServiceName%,,FileSpy.Service //////////////////////////////// Please do let me know if you need further information in this regard. Thanks a lot! Regards, Rohit Dhamija

Thanks Dear, I am developing my application only for Windows2000 (no Win9x systems) So I there any simpler way out for my doubt ?? Thanks a lot. Regards, Rohit Dhamija

Dear All, Code project people has helped me a lot during my initial career by flooding me with useful solutions & valuable comments to my doubts. Thanks a lot for that. I have another small question. I am developing an application in which I am running an executable (the job of this exe is to move some files from one location to the other, etc.). This exe is built using "Win32 Console application" provided in Visual C++ Version 6.0 When I run the application, it calls my exe, and this running exe shows its console window and performs its required operation successfully and close downs decently. BUT I DONOT WANT THAT CONSOLE WINDOW TO BE DISPLAYED DURING MY APPLICATION. I cannot change the application since I don’t have the code for that, but I can easily do the same for my exe. So can any body please tell me how to hide the console window or console should not be displayed. Regards, Rohit Dhamija

Dear All, I am developing an application in MFC VC++ Version 6.0 for Windows 2000.

But unfortunately my program doesnot starts in the safe mode automatically because Run entry in registy doesnot work in this case. Please suggest any way to run my application in safe mode also. Feel free to ask any further queries in this regards, Thanks Rohit Dhamija
