If you're converting to a dll, I assume you're hoping to access some classes in there, not execute any sort of UI ? You can compile with /clr and write a managed layer that you can import into C#. Which is easier really depends on the code you're working on.

Hi I have two 'LPSTR' (or char *) variables and I need some help in figuring out how to insert a number inbetween these two and join (strcat) the two LPSTR variables. I apperciate any help I can get, Thanks!

Ex:

LPSTR test1;
LPSTR test2;

test1 = "hello";
test2 = "world";

int x = 9;
char buffer[10];
itoa(x,buffer,10);

//I need to end up with 'hello 9 world'

You can do this:

char test1[256];
char test2[256];

sprintf(test1, "hello");
sprintf(test2, "world");

int x = 9;
char buffer[256];
sprintf(buffer, "%s %d %s", test1, x, test2);

the buffer will contain 'hello 9 world'

Opening Network Connections dialog

I have a network device app that resides in the system tray. I added a context menu to this app to enable and disable the device. Right now I'd like to add an additional context menu item to display the Windows "Network Connections' dialog box. This is the same dialog that one sees on clicking "Network Connections" in the Control Panel.

Has anyone tried this before? Would appreciate any help in this regard.

Thanks.

I would like to help but i am not sure about what i write below, just try it.

since it is a control panel application, you might use WinExec or Shell execution functions to execute the .cpl file...

hope this helps

restricting CSplitterWnd pane to minimum size

Hello all, I'm trying to restrict the left pane of a split window to a certain size. For instance, the left pane should not be allowed to get smaller than 100 pixels, but it can get wider; same for the right pane. There is a minimum arg when creating pane, but that just means if it gets under 100 pixels, it closes all the way up. I would like for it to not get any smaller than 100 pixels. I've seen articles that tell you how to lock the bar, but this is not what I want.

Thanks in advance.

BD,

I worked with some splitter stuff like this in ancient memory. Right off the top of my head, I'd suggest you take a look at handling the resizing messages as I recall that's how I did it. I don't remember if it was as simple as WM_SIZE, but look at the splitter wnd documentation & see what size oriented messages they respond to.

I do realize this is a bit vague, but it might point you down a productive path. Hope it helps.

Take a look at Infozip (http://www.info-zip.org/[^])
AFAIK, both java.util.zip and Winzip are built on Infozip, so compatibility isn't an issue here.
I've been using it for years, no problem.
And it's free.

Question about thread in C++

Hi All.

I try to write some application and i use the function
_beginThread(...)....EndThread() and i don't understand how can i stop the running thread.

When i create 1000 thread i can stop some thread by using sleep - but what i want to do is to stop thread with some other way and make the thread to continue run when i need to.

( in java i can do in simple way "stop" and "notify" for continue thread run)

Thanks for any help.

So just use CREATE_SUSPENDED when creating it.

The CREATE_SUSPEND flag is just for using ResumeThread(...) - but if the current thread is running ... how can i stop him and again set the thread continue running ? ( i guess that using ResumeThread again will make the thread run again )

Wrong. Why would you even think that? When you call a function named ResumeThread(), what purpose would a CREATE_SUSPENDED flag serve? _beginthread()

Read the article I provided you. It plainly shows how to start, stop, suspend, and resume threads properly.

How To Delete A Specific Character In A String !!!

Mark_Murphy19-Sep-06 9:15

Hi

I am new to C++
Just wondering if anyone can help out here.

I have a string consisting of all the letters of the alphabet.
eg: string Alphabet ("A B C D E F G H I J K L M N O P Q R S T U V W X Y Z");

I need to erase a particular letter of the alphabet within the string. eg H and then display the string back to the console app minus the letter erased.

I have tried playing around with Alphabet.erase() but so far have only managed to reduce the length of the string, not erase a specific character within it.

Can anyone show me how I could do this

Thanks in advance !!!

I really hate this darn machine;
I wish that they would sell it.

// predicate
bool removeChar(const char& c)
{
	if ('h' == c || 'H' == c)
		return true;
	return false;
}

// in code
string alphabet = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
alphabet.erase(remove_if(alphabet.begin(), alphabet.end(), removeChar), alphabet.end());

To erase the letter, the previous solution works. The code below replaces the letter with a space:

wstring alphabet = L"ABCDEFGHIJKLMNOPQRSTUVWXYZ";

wstring::size_type pos = alphabet.find(L'H');

if (pos != wstring::npos)
alphabet.replace(pos, 1, 1, L' ');

wcout << L'[' << alphabet.c_str() << L']' << endl;
