Hi Guys,
I am facing a problem while playing with different styles of the Edit Control. I want to toggle between the alignement styles ES_LEFT,ES_RIGHT and ES_CENTER at run time through selecting them through radio buttons. I have tried to do it through the following code, but it does't work in case of above stated style bit whereas the same code
works correct for ES_LOWERCASE and ES_UPPERCASE bits;
DWORD dwStyleOld;<br />
DWORD dwStyleNew;<br />
CRect rect;<br />
dwStyleOld = m_EditCtrl.GetStyle();<br />
dwStyleNew = dwStyleOld & ~ES_LEFT;<br />
dwStyleNew = dwStyleNew | ES_CENTER;<br />
m_EditCtrl.ModifyStyle(dwStyleOld, dwStyleNew);<br />
m_EditCtrl.GetWindowRect(&rect);<br />
InvalidateRect(&rect);
Regards,
Nasir Maan

Try something like this instead:
<br />
DWORD dwStyle = GetWindowLong( GWL_STYLE );<br />
dwStyle &= ~ES_LEFT;<br />
dwStyle |= ES_CENTER;<br />
SetWindowLong( GWL_STYLE, dwStyle );<br />
There are 10 kinds of people - those that get binary and those that don't.

sir,
I have tried it also...but unfortunately there is no success.

Try this instead:
m_EditCtrl.ModifyStyle((ES_LEFT | ES_CENTER | ES_RIGHT),ES_CENTER); The first argument to ModifyStyle are the styles to be removed, and the second argument are the styles to set. So ModifyStyle does the 'and-not' and 'or' operations for you.

Netmeisters,
I am trying to do something which should be simple. Using Visual C++ I want to create a map containing an STL string as a key and my own type as a value.
#include <string>
#include <map>
#include <iostream>
using namespace std;
map<string,CReport>slips;
Then to add a pair to the map:
string str;
pair<map<string,CReport>::iterator, bool> ret =
slips.insert(map<string,CReport>::value_type(str,report));
But this produces a host of error messages that I've included below.
Can't figure these out at all. When I comment out the pair<map etc line the messages go away.
Any assistance much appreciated.

It compiles fine for me, are you sure it's not some other thing that is causing the trouble? Maybe post some of the code surrounding this snippet.
cheers,

For extracting the essence out of these weired error-messages, you can try using STLError Decryptor[^]
For me, it works fine - and it is free
My opinions may have changed, but not the fact that I am right.

You must make sure you have an #include <string> in your source file. Frequently you'll get things to compile with the declarations looking fine, but when usages start if the actual include isn't there then the compiler doesn't know what to do. I think this is being caused by the underlying compiler mechanics of how it instantiates templates.

Hello all,
How can i send a fax(by dialing a phone number and then sending the fax) by VC++ ?
Please introduce to me some documents and source codes 
Regards,
Hadi Rezaee
|
|

TAPI will handle the dialing of the phone number. Sending the FAX is much harder because the protocol isn't supported natively in Windows.
If you are using Win2k have a look at http://msdn.microsoft.com/library/default.asp?url=/library/en-us/fax/faxabout_3wv9.asp[^]

Hello dear Michael
Thanks for reply, the document was useful too
hmm, I'll talk with my boss about it ...
In fact the current version that i'm working on it has named Special Version and actualy it has special users, not public version, and i think we should limit the user  (WinXP is good choose !!!)
The last Microsoft Fax Service is supported by WinXP and WinDotNet2003

Hi,
I'd like to know how to kill a known process without knowing its process id. For example, if I have a process listed in the taskmanager process list as "bad_process", can I use the string "bad_process" as input to some function in order to get a handle on that process to kill it?
Any help would be appreciated.
Many thanks in advance.
Sincerely,
Jonathan.

There is a Kill.exe util that comes with some resource kits that takes a process name, internally looks up the process id and then calls terminate process using that id. MSDN has the sample project that builds this tool and shows you how to look up the process id based on title. You can get the sample here[^].

Many thanks Erik! That is all I need for my purposes.
Cheers,

I´d like to save an array in a file. How could I save it in VC++?? And how could I retrieve it??
Thanks,
d.f
|
|
|
|

It is up to you which format you choose to store the data of the array. A simple possibility would be:
lengthCRLF
data<sub>1</sub>CRLF
..
data<sub>n</sub>CRLF (CRLF means new line) that is, one piece of data per line, beginning with the length of the array. Reconstructing the array from this info should be straightforward.

Is there a way to create a menu for a dialog box? Thanks.

Sure, create your menu with the resource editor, then go to the dialog resource, open its properties popup and select the menu in the Menu combobox.

Does anyone know if there are issues using this function within a dll call? I am trying to use it to wait for a global mutex handle, and it seems to never recognize that the mutex is available. If I use WaitForSingleObject(), it works fine. There are reasons for wanting to use the MsgWaitForMultipleObjects() so I cannot just shrug it off, and go with WaitForSingleObject().
Any ideas?
HANDLE ghAcess;
From within some function:
<br />
if (ghAccess == NULL)<br />
ghAccess = OpenMutex(MUTEX_ALL_ACCESS,FALSE,"AccessMutex");<br />
<br />
DWORD dwWaitResult = MsgWaitForMultipleObjects(1,&ghAccess,TRUE,100,QS_ALLINPUT);<br />
switch (dwWaitResult) {<br />
case WAIT_OBJECT_0:<br />
case WAIT_ABANDONED_0:<br />
return(ghAccess);<br />
default:<br />
break;<br />
}<br />
|
|
|
|
|
Are you sure you are using MsgWaitForMultipleObjects the right way? With bWaitAll set to TRUE, the function only returns WAIT_OBJECT_0 is there is some input in the queue. Is this what you want?

What I am looking for is a way to wait for the mutex (ghAccess) to become available while allowing messages to be processed.

Hi,
I keep getting a syntax error "C2059: syntax error : 'constant'"
When I try and specify a capacity for a vector based type.
<br />
...<br />
typedef std::vector<myClass> MyClassVector;<br />
...<br />
MyClassVector mcv (100);
<br />
I just stare and stare yet I cannot see the syntax error?
Thanks!

Which compiler are you using? The following compiles fine in VC++ 6.0sp5:
#include <vector>
class myClass{};
typedef std::vector<myClass> MyClassVector;
MyClassVector mcv (100);
int main()
{
return 0;
}
