When i post code here and use the <code> </code> tags all it does in change the color of the font and I loose the tabs. How are some people able to change the background color from this blue to the codeproject beige and keep the formatting???????

Use the proper tag. Check the stylesheet.

Thanks Ryan,
That did the trick. I actually spent time digging around the css for the <proper> tag. Now, don’t I feel stupid. I guess this proves I'm not a "web page programmer" - whatever they are.

Hi,
I am using VC++ and able to open an Excel file: File.xls (if it does not need a Password) with the following code:
<br />
CDatabase database;<br />
CString Xfile = "c:\\File.xls";<br />
<br />
sDriver = GetExcelDriver();<br />
if( sDriver.IsEmpty() )<br />
{<br />
AfxMessageBox("No Excel ODBC driver found");<br />
return;<br />
}<br />
<br />
sDsn.Format("ODBC;DRIVER=<br />
{%};DSN='';DBQ=%;PWD=ATC",sDriver,Xfile);<br />
database.Open(NULL,false,false,sDsn);<br />
However, with the same file, if I use Save As (with
Option) with Password:ATC, then when I run the same
program, it said: Could not decrypt file
Anyone knows what was wrong?
Many thanks

Hiya I have a string like:
char buffer[] = this,is,not,needed,12,grahamoj,34,this,is,not,needed,either;
What I need to do is search for 12 and then do a search after that for the 34, and extract the part in between them e.g "grahamoj" for displaying..
I have been using strstr to search the string but can't get it right.
Can anyone help me on this..
Thanks.

char buffer[] = "this,is,not,needed,12,grahamoj,34,this,is,not,needed,either";
char *p1 = strstr(buffer,"12,");
if(p1)
{
p1 += 3;
char *p2 = strstr(p1,",34");
if(p2)
{
*p2 = 0;
printf("%s",p1);
}
}

 I don't get when the current selection is actually the new selection made by the user. When I'm calling GetCurSel()with my combo box, I'm getting the previous value that was in the combo box. I've tried it in OnOk, OnCurSel,OnSelchange and OnSelendok. Each time the currently selected item is seen as the previous item, not the new item that was selected? What's up with that?
Here's the code I'm trying to execute! 
void RDialogForControlSegments::OnSelendokSegmentGainMatrixCombo() <br />
{<br />
this->m_dwGainMatrixId = <br />
this->m_ctrlSegmentGainMatrixCombo.<br />
GetItemData(this->m_ctrlSegmentGainMatrixCombo.GetCurSel());<br />
<br />
}

 I figured it out. It was a LAME mistake!

Intellisense shows that I can access myPlines (myGroups[i]->)... why can't I access myVerts? (see bold code below). Shouldn't this work like a nested structure? Thanks for any help.
class Group
{
public:
list < Pline * > myPlines;
void addPline(Pline *p) {myPlines.push_back(p);}
}
class Pline
{
public:
void addVert(CPoint *v) {myVerts.push_back(v);}
void removeLastVert() {myVerts.erase(myVerts.end());}
list < CPoint * > myVerts;
};
**********FormView.h****************
Group *myGroups[10];
*********FormView.cpp ***************
FormView::OnDraw(CDC* pDC)
{
pDC->Polyline(myGroups[i]->myPlines[k]->?
}
**********************************************************
**********************************************************
I had hoped it'd work like this:
*************** Nest.h *******************************
typedef struct {
int *x1;
} One;
typedef struct {
One *x2;
} Two;
typedef struct {
Two *x3;
} Three;
class Nest
{
public:
Nest();
Three myNest;
virtual ~Nest();
};
************** Nest.cpp *********************************
Nest::Nest()
{
myNest->x3->x2->x1 = 10;
}

The STL list, which you have used for myPlines, does not overload the array access operator, []. If you need to access it using this operator, you should use a vector instead, otherwise you should be iterating through the list, rather than trying to retrieve an item at a specific index.

Hi,
I have a function
bool equal(double val)
{
if(val == 0.0) return true;
else return false;
}
if val = 0.0;
function will return true
if val = 0.0000000000000001;
function will return false
Is there a way to set a tolerance so that 0.0 == 0.000000000000001 -> true?
Thanks
Everything's beautiful if you look at it long enough...

Sure, you can try something like:
<br />
bool equal(double val)<br />
{<br />
if(fabs(val) < 0.00000000001) return true;<br />
<br />
else return false;<br />
}<br />

Thanks for the link. It looks like a good and efficient solution.

Hi all
where can I find a combobox that displays the shell tree (like the one in the Windows explorer)? I need it in my MFC app
|
|

One solution is CTreeCtrl.

Hi !
I created a FrameWnd and attached a tool basr to it, but when I scroll the window, the tool basr moves with the window and goes away...
Any way to fix it ?

I am writing a filter for an array of classes. I want users to type in the filtering parameters as text in a script file. E.g.
Price > 10;
Country = "US";
Currency = "CAD";
Years <= 5, etc.
The c++ code should then create an unfiltered array, read this file, and then filter the array. One way of doing this is to come up with a bunch of if statements:
if( sLHS == "Price" )
{
if( sSign == ">" )
if( GetPrice( ) > 10 ) bPassed = true;
else if( sSign == "<" )
if( GetPrice( ) < 10 ) bPassed = true;
...
}
...
if( sLHS == "Years" )
{
if( sSign == ">" )
if( GetYears( ) > 5 ) bPassed = true;
....
}
and so on.
With many parameters to choose from I am going to end up with a thousand of if statements. I AM LOOKING FOR AN EASIER WAY AND I NEED YOUR HELP.
It would be really nice if I could come up with an array of something like this:
Price GetPrice( );
Country GetCountry( );
Years GetYears( ), etc.
then go through the array, find the corresponding item in the left column and then call a specific function in the right column based on its name. BUT HOW CAN I DO THIS AT RUN TIME?
Any thoughts are appreciated.
Thanks

what you could do is come with a structure
typedef struct {
string name ;
static void funcPointer ;
}REQUEST ;
Now add a function to just compare the name and for a match call the static function in the class .

Thanks for the reply. A few additional questions:
- How do I get a pointer to a function?
- How do I call this function after I have the pointer?
- What if I need to pass certain parameters to the function?
Thanks
