template <typename ForwardIter> void MyFunction(ForwardIter start, ForwardIter end)
{
while(start != end) {
doSomething(*start);
++start;
}
}
char temp[100];
MyFunction(temp, temp + 100);Would be a cleaner solution, as your will only work with std::vector. This'll work with any iterator.

Like I said, untested code, and I'm a little rusty on C++ templates, but I figured it was essentially ok, and certainly illustrated what I wanted to suggest.

[EDIT]
Sorry did not read all the posts, but this problem screams for a template approach...
[/EDIT]
template<class T>myFunction(T* data)
{
}
int main()
{
char tmp[100];
float fTmp[1000];
myFunction<char>(tmp);
myFunction<float>(fTmp);
}

Hi,
I use the function ShellExecute to open a PDF-file from my c++-programm (ActiveXControl). I want to highlight one word on the pdf-file. Can I do this with ShellExecute or have you another idea how I can realize that.

In my SDI application , I have a ToolBar with 10 buttons .
I am unable to Change the text displayed in this Button .
I named the button ID_NEWBUTTON and have a event handler in CMainFrame.
I tried to change the text in the Toolbar button using
m_wndToolBar.SetButtonText(m_wndToolBar.CommandToIndex(ID_NEWBUTTON),"Please change text");
Still nothing seems to be happenning ?

How can I programatically change the Color of a ToolBar ?

Hi,
try this
<br />
SetClassLong(m_wndToolBar.m_hWnd, GCL_HBRBACKGROUND, (LONG)::GetStockObject(WHITE_BRUSH));<br />

I have an SDI framework where my Chidlview creates many Dialogs within itself .
I want to trap a keyboard entry in one of the dialogs . For this I went to ClassView and added the event Handler with a dummy AfxMessageBox
This event is not getting fired ? Suggestions are needed .
|

Hello,
Where did you add the event handler? The OnChar() handler should be added to the dialog in which you want to trap a keyboard entry!
hope this helps a bit...

Sorry the subject was hard to summerize.
I have created a function that I thought was type independent, meaning that it didn't matter what type of an array was passed to the function. It would just write the data with a comma seperation.
I have 2 structure in a class called RFMAccess:
struct TSimHeader
{
char Name[47][21];
char Unit[47][21];
double Min[47];
double Max[47];
int SignalCount;
int SimStatus;
}static TSimHeader_arr[10];
struct TSimSignal
{
double Value[47];
double TimeStamp;
}static TSimSignal_arr[10];
The data in these structures gets updated 2x a second.
I also want to write the data to a file 2x a second so, I created a function that I thought would do this without having to declare the array type. I want to be able to use this later in other projects.
Here is my function.
I am doing something incorrect here, but just not sure what it is.
ofstream fout ("test.txt");
bool firstTime = true;
int passes = 1;
void LogData::writeData(void *data){
int count;
if(firstTime){
fout<<"flight_data,";
for(int i=0; i<RFMAccess::TSimHeader_arr[0].SignalCount; i++){
if(i == 0){
fout<<data[i]<<endl;
passes++;
if(passes == 2)
writeData(RFMAccess::TSimHeader_arr[0].Unit);
else if(passes == 3)
writeData(RFMAccess::TSimHeader_arr[0].Min);
else if(passes == 4)
writeData(RFMAccess::TSimHeader_arr[0].Max);
else if(passes == 5){
firstTime = false;
writeData(RFMAccess::TSimSignal_arr[0].Value);
}
}
else
fout<<data[i]<<",";
}
}
if(!firstTime &&(flight_data->log == true)){
if(i == 0){
fout<<data[i]<<endl;
writeData(RFMAccess::TSimSignal_arr[0].Value);
}
else
fout<<data[i]<<",";
}
}
Thnaks for the help,
Steven

What is the actual problem your getting?

It's saying that the type of void is unknown or zero.

Hi, all
I am experiencing a problem, when I change an edit box into readonly/lock state the backgroundcolor of control changes into the buttonface system color. How can I prevent this or choose a different color?
Thanks in advance

u have to trap the OnCtlColor() event but as i recall edit boxes dont play nice and repaint themselves in a few places so it can be a bit of a b*itch
"penguins have no bill"
biz stuff about me

return a White Brush in OnCtlColor()

Ok, Thanks mates
I will try that out

This is the default windows behavior. Unless it is absolutly necissary I would not change it because it will confuse your users who will expect to be able to edit the box.

Hey! I'm trying to get a child dialog to show up in a pure Win32 app.
What I want to do is use the dialog as half of the UI and use a simple ListBox (created with CreateWindowEx) as the other half.
Here's what I'm trying:
hCtrls = CreateDialog( hInst, (LPCTSTR)IDD_GAMEINFO, hWnd, (DLGPROC)DlgGameInfo );
The line of code works for all non-child dialogs (like my About and Options dialogs), however as soon as I specify in the resource editor that my IDD_GAMEINFO should be a child it doesn't work.
Any help is appreciated! Thanks

The hWnd is the HWND variable that the main window's WndProc message handler recieves.
In the switch statement for the various windows messages I basically have the following to create my UI:
case WM_CREATE:
HWND hCtrls;
// Listbox works
hCtrls = CreateWindowEx( WS_EX_CLIENTEDGE, "LISTBOX", "",
WS_CHILD | WS_VISIBLE | WS_VSCROLL | WS_HSCROLL,
5, 5, 200, 340, hWnd, (HMENU)IDC_GAMELISTBOX,
GetModuleHandle(NULL), NULL);
// Static frame works
hCtrls = CreateWindowEx( WS_EX_CLIENTEDGE, "STATIC", "",
WS_CHILD | ~WS_VISIBLE | SS_GRAYFRAME,
210, 5, 250, 340, hWnd, (HMENU)IDC_GAMEINFOFRAME,
GetModuleHandle(NULL), NULL);
// CreateDialog returns a NULL (IDD_GAMEINFO is my dialog resource)
hCtrls = CreateDialog( hInst, (LPCTSTR)IDD_GAMEINFO, hWnd,
(DLGPROC)DlgGameInfo );
// I also added this later to try it...but it didn't help:
ShowWindow( hCtrls, SW_SHOWNORMAL );
UpdateWindow( hCtrls );
I experimented a bit...the code with no modification works if I specify in the resource editor that the dialog is a regular popup with a border, etc. But of course then it's a popup...and I want it a part of the actually window. (Like a common control would be)
Thanks,
./[tiller]

Not sure that this is your case, but for child dialogs you have to ensure that the WS_VISIBLE style attribute is set in the resource.
|
|
|
|
|
Yeah...I have WS_VISIBLE selected.

I have a member variable of a class declared as a pointer to type double, m_dHessianMatrix. This variable will be holding a 2 x 2 matrix (could be larger)and needs to be initialized completely to zeroes to start. As such, I need something to init the matrix to zero quickly (thus a for loop will not do particularly for LARGE matrices).
Currently I am initializing the matrix data in the constructor as follows:
CROT_Optimizer::CROT_Optimizer(UINT MaxNodes)
{
ASSERT (MaxNodes > 0);
if (MaxNodes == 0)
return;
m_uiNumberOfNodes = MaxNodes;
m_uiNumberOfSprings = 0;
m_ppNodeIndexedSpringArray = NULL;
m_dHessianMatrix = NULL;
m_dHessianMatrix = new double[4];
memset(m_dHessianMatrix, 0, sizeof(double));
}
However, I don't like this for two reasons.
1.) I have to include string.h to gain access to the memset function ->code bloat 
2.) It is not aesthetically pleasing to the eye
Is there a way to initialize the matrix without using a for loop and without using memset()?
