No ,this will not overwrite the Memory Space.
if you have created object and collected the Reference it's just a reference (i.e. constant pointer).If you will assign it a new address it 'll not delete old object.(As it should not, Bcoz that object may be used ant where else).So if you are sure it is not usable now.Then call delete on it first .Then create new and assign value to it.
But if you are not assigning new value , set it to null ('ll save from Dangling pointer).
So you can say
if( myObject != NULL)
delete myObject;
myObject = CreateObject(); //or myObject = NULL;
It's not enough to be the best, when you have capability to be great....

Is your project set to build for unicode?

I am using the ShellExecute API to launch default E-mail client like "emailto:Email Ids". It is working well but when the number of characters exceed 1852, its not launching the E-mail client. The API is still returning success code only. My default mail client is Mozilla thunderbird. Is this a restriction in the API or any chance for E-mail client?
Thanks

Are you by any chance running Win2k or earlier?
This article[^] may be of interest. The resulting command line may exceed 2047 chars.
However, I personally find an email address that exceeds 1852 chars to be rather uncommon.

The field can have more than one E-mail, so it may exceed 1852 occasionally. I checked same thing in system with outlook/Win XP the max limit was 1863.

Should be rather OK as long as you don't have to spell your email ID out to someone over the phone.

I'm assuming that you are clubbing too many email ids separated by semicolons? I tried by increasing the no. of email ids with every trial. At some point, ShellExecute started returning a value NOT greater than 32 (it returns a value greater than 32 if it succeeds) and the return value was, upon failure, SE_ERR_ACCESSDENIED.
You might want to check the return value properly.

I think it has to do with the lenght of the commandline. What you could do is put your line in a batchfile (just generate the file from within your program) and run that one. Just delete it when ready..

Well, what do you have? A CWnd*? Nothing?
You could probably benefit from ::FindWindow()[^] or ::EnumWindows()[^].

What window? Is one of your application windows? Please provide details.

You approach the window gently, and say: "Hi Window, may I please have your handle? Thanks!".
Seriously though, you need to provide more information than that to get an answer that can be of use.

Brother..
Give details correctly...
Normally in visual programming all controls like list control,button everything is considered as a window.
Specify the need ...

Thanking you

But the OP should help us help him. He needs to give us more information. I can ask him the following:
Which window's handle do you need? Is that window a part of your application? Is it the window of an application that you are spawning? Is it a control that is within a window that you own?
There are too many unknowns for us to answer. These guys are very helpful, but the OP needs to be precise. He should read the guidelines[^]

See if the following helps you.
CWnd::GetSafeHwnd - Returns m_hWnd, or NULL if the this pointer is NULL.
You need to google first, if you have "It's urgent please" mentioned in your question.

Hello to all,
In my project I am using a USB device and collecting data from it.when I connect that device to my computer then I get "USB Serial Port" in device manager with the port number.Now by default latency timer of that perticular port is "16" and I have to make it "10" to get the data with our required speed. But this change in latency timer can be done manually.To change the latency timer I follow the below steps-
1)right click on "My Computer" icon on desktop.
2)then follow the path, "properties->Hardware->Device Manager->Ports->USB Serial Port(COM X)" where "X" stands for port number of my device
3)then doble click on that port number ("X") and follow the path,
"Port Settings->Advanced" here you can set latency timer of that perticular port under the "BM Options" heading. Here I change latency timer from "16" to "10" from the list.
This latency timer setting can be done manually but my question is that,is there any method or API or any other way in VC++ to set this latency timer programatically? Anybody knows how to do it? please help me out this is really very urgent.
Thanks and Regards,
Anay

Ask the vendor.
The driver used is most likely provided by the vendor and the "latency timer" you are talking about is not a serial port setting. So I guess that the "latency timer" can be set by using ::DeviceIoControl(). What IOCTL to use and what values to send should be readable in the documentation provided by the vendor.
