I encounter the following problem within my program. When the user is prompted to input a number the following happens to the calculations. When $2000 is input the calculation comes out fine i.e., 4% +$80.00. The problem comes if the user enters $2,000 the 4% shows up as o.o8. The comma is causing a problem. Can someone help me overcome this problem. Other than that the program works fine. I have tried cin.ignore() to no avail. Since I am just beginning C++ I am lost.

dialogs children are not resized automatically.
you need to handle WM_SIZE and resize and reposition you web browser control.

Hi,
I have created an ATL dll which has a modeless dialog box containing a WebBrowser control. My problem is that whenever I'm pressing TAB key over the WebBrowser control, the focus is not shifting to other controls or links within the web page which is getting displayed within the control.
I have implemented a hook to trap WH_GETMESSAGE message, after that I'm able to get response from the 4 arrow keys and TAB key, but that too within the dialog box.
I have to make the TAB key acting normal within the WebBrowser control that is within that dialog box.
Can anyone of you help me out? Thanks in advance.
Regards,
Ashish

i fail to envoke shutdown function.
i m trying to write the data recd in the socket buffer to a fiel.
though i manage it but it happens only i stop the application and not before.
i tried many alternatives but feel i m still short of something.
Seeing the given code can i be suggested why????
// THe following is a client thread
<br />
UINT ClientThread(LPVOID pParam) <br />
{<br />
char *buff;<br />
CString cmd;<br />
CString params;<br />
int n;<br />
int flag=0;<br />
BOOL auth=false;<br />
buff=(char *)malloc(1);<br />
SOCKET client=(SOCKET)pParam;<br />
recv(server,buff,sizeof(buff),0);<br />
while(true) <br />
{ftxt=fopen("d:\\amit\\COMMAND.txt","a+t");<br />
while(n=recv(client,buff,sizeof(char),0))<br />
{<br />
flag=1;<br />
<br />
<br />
fwrite(buff,sizeof(char),1,ftxt);<br />
<br />
if(n==SOCKET_ERROR ) <br />
break;<br />
buff[n]=0;<br />
cout<<buff;<br />
}<br />
shutdown(server,2); <br />
<br />
fclose(ftxt);<br />
<br />
}<br />
<br />
flag=0;<br />
closesocket(client);<br />
return 0;<br />
}<br />

I do not know about your actual problem, but you have other problems.
char *buff;
buff=(char *)malloc(1);
recv(server,buff,sizeof(buff),0);
recv(client,buff,sizeof(char),0);
buff[n]=0;
1) Allocating a 1 character buffer makes no since and you never free the memory allocated. Just declare a single character variable or a small buffer: char buff; or char buff[1];
2) These two statements are not the same thing:
recv(server,buff,sizeof(buff),0);
recv(client,buff,sizeof(char),0);
sizeof(buff) == sizeof(char*) NOT sizeof(char);
If you had declared the buff variable as buff[1] or buff then
sizeof(buff) would equal sizeof(char).
3) buff[n]=0;
if n is anything other than 0, then your thread may (should) crash.
buff[1] = 0; // ERROR
4) Unless you have a good reason, constantly opening and closing the file in the outer loop is probably a bad idea too!

Taking char * buff has a strong reason behind as i m trying to recv a string eg. SYNTAX like <green>Operator play file abc.wav
yeah a typing err n i apologize fr recv(server,....)it was n shud be recv(client,....).
Constantly opening and closing file is reqd as the client may keep sending data.
eg. 1.
open channel ch_id,play file filename,record fiel fielrec , etc...
i want to envoke shutdown in the outer loop
n yes i ddnt free memory was my mistake..for once the data is written to the fiel the memory shud have been freed n file closed.

You still do not need to allocate a buffer, since all you need is a pointer to a single character.
Hmmm! I should have noted that recv(server,...) was a typo, since that was a typo, then shutdown(server...) is also a typo.
I looked up the functions used and here is what your code will do once the typos are fix:
FIRST TIME TRU LOOP:
1) Read 1 byte from the socket and then ignore it.
2) START INFINITE LOOP {
3) Open a file.
4) While( there is a byte received OR a SOCKET_ERROR ) {
5) copy byte to file. // before checking if error occured
6) if( error )
break;
}
7) Shut down socket so you can no longer send or receive and data.
(This means recv(...) will now always return SOCKET_ERROR)
8) Close file.
9) } // END OF INFINITE LOOP
AFTER FIRST LOOP:
1) START INFINITE LOOP {
2) Open file.
3) While( SOCKET_ERROR ) { // because of shutdown above
4) Write the last character received (during first loop).
5) Break out of loop (since it was a SOCKER_ERROR).
}
6) Try to shut down again (cann't because it was already done).
7) Close file.
8) } // END OF INFINITE LOOP
I do not think that was what you were trying to do, but that is what should be happening. There is also the fact that the INFINITE LOOP cann't be stoped properly (any other way if bad).

To work with the list view control in win32 you just SendMessage any of the LVM_* list view messages to the control. The info will either be the return value, or contained in the structures you pass in as the message parameter.
For example to get the number of items in the control:
int NumItems = SendMessage(HWNDListView, LVM_GETITEMCOUNT, 0, 0);

Hi,
I am having a problem with updateResource API with strings.
I want to delete all the strings in a string Table and rewrite them in another language.
This creates 2 sting tables
1. the new destination string table with the new strings.
2. the older string table (All the strings are however deleted here)
on selecting the older sting table in the resource editor(VC.NET), the editor throws an error and shut down throws
I want to get rid of the older String table
PS NOTE: the application works properly in some computers but in some computers, the above mentioned problem occurs...
Could i know the reason for the same, and the process of getting rid of this problem..
thanks in advance..

Hi,
I need to generate a lot of Excel files. I don't want to use Excel Automation (Excel version dependant, perf, etc.  ). So, I'm looking for a good C++ library to create spreadsheets dynamically...
No C#, No .net. ActiveX would be ok. (actually, I'm using STL/ATL)
Nota:
CSV files do not match my requirements cause I have to customize cells, borders, colors and so on...
Can you help me ?

Thanks for any help...
