It seems the horizontal bar cannot be used as you expected. It is supported by the list box only in case of multicolumn lists, and does not perform horizontal scrolling for long items.

I think you can try an alternative solution based on "list control" instead of "list box" (available in Dialog Editor too). When a list control is used in Report mode, it looks like a list box with or without header, but with new features, like horizontal scrolling.

I hope this helps.

Hi all,

I have this try catch block,

try{
 rc=SQLConnect(hdbc,chr_ds_name,SQL_NTS,chr_ds_username,SQL_NTS,chr_ds_password,SQL_NTS);
}
catch(...)
{
...
}

But the thing is the catch block doesn't seem to work, my whole application fails and closes down. Confused | :confused:

Can anyone help??

Thanx alot

catch will execute, only if SQLConnect throws some exception or, code after call to it catch block throws exception.

That may be necessariy because of passing some invalid parameters to SQLConnect.

First of thanx for the reply..

"...That may be necessariy because of passing some invalid parameters to SQLConnect..."

O.k, but if what you you are saying is true, then the catch block will catch it .. right?

As I said earlier,catch will execute only if exception is thrown from try block.
In above case, its not necessarily checked by SQLConnect for invalid memory.
consider this code for understanding

int foo1(char* p)
{
	try 
	{
           memset(p,0,10);
	}
	catch(...)
	{
	   throw;
	}
    return 0;
}

int main(int argc, char* argv[])
{
try
{
	char *p=NULL;
	foo1(p);
}
catch(...)
{
  cout<<"in Catch"<<endl;
}
}

In you case foo1 like implementation might not implemented by SQLConnect.
If you try removing try, catch from foo1 function, above code will crash irrespective of try, catch in main.

How to integrate msxml 6 with my installer

I want to make installer of my project. I want to integrate msxml6.dll with my project.
as far as i know there are two ways in which i can instanciate msxml6.dll object.
1. Put it in system32 so it can be retrieved by application at run time : But this will break if someone elese updates it or repairs OS.

2. Put it in my program directory, make a registry entry in my namespace and While instanciating [CreateInstance()] I supply exact path (from registry) of DLL to be instanciated.

Now, I am not sure about how second option to be coded.

Is there any other approach ?
I went through tutorial given by msdn for the same. The have merge module for msxml4. I am not sure how to do it for msxml6. Please help.

You shouldn't be installing MSXML yourself. Use the redistributable installer from MS.

Ya, i used Find().
I need one more help that is my string reads like this
"pv m3 PV|| sv m3 SV||MD||"
here i want to extract the string " sv m3 " from the above string.The number of characters may vary.But space and new line are used to seperate the words.
Pls help me out.
I think u get my point.

Thanks for reply..
I explain you my need in details.
First the string is like this sTemp="sub m3 PV||add m3 SV||MD||"

Then i have to extract few things and i have to put in to seperate string
Final String, CString StrFinal = "PV||SV||MD"
I know to extract first two things i.e., sub m3

i did like this

int pos2 = sTemp.Find("\n");
sTemp3 = sTemp.Mid(pos2-3);
sTemp=sTemp3;
here STemp = PV||add m3 SV||MD
And then i have to extract add and m3.
But i dont know to extract the middle add m3 . i need this thing

prasad_som4-Sep-06 22:42

4-Sep-06 22:42

Cant you use same logic? i.e.
I assume each sub string you mentioned here is preceded by '\n'.
And what does || stands for ? Is it a kind of separator ? If yes, you can use it,too.
i.e. Find "||" and extarct 2 chararacters preceding it.
Keep appending result string.

Do you need to get a middle a string like your example?

WhiteSky

Anu_Bala4-Sep-06 23:34

4-Sep-06 23:34

Yes,that || is a newline character which is displayed like this in our coding.

Is it possible for you to find space between add m3 or you dont have a space in your string

Hi,

You can use Strcmp function to compare two strings.
