Is it possible to concatenate variable/pointer names?

[Queeto]

I have 5 pointers like:

pA0->SetWindowText("");
pA1->SetWindowText("");
pA2->SetWindowText("");
pA3->SetWindowText("");

I would like to use a loop to make it easier, something like:

for (i=0;i<4;i++)
{
(pA + i)->SetWindowText("");
}

Hello!

This is sadly not possible, but something like this:


void MySetWindowText(CWnd* pWnd)
{
pWnd->SetWindowText("My window text");
}

int main(void)
{
// a lot of code here

std::vector<CWnd*> vectorWindows;

vectorWindows.push_back(pA0);
vectorWindows.push_back(pA1);
vectorWindows.push_back(pA2);
vectorWindows.push_back(pA3);

std::for_each(vectorWindows.begin(), vectorWindows.end(), MySetWindowText);

// more code...

return(0);
}




Sincerely,
Wolfgang Petroschka (aka void*)

If this was an answer to a question, please rate it!!!

I don't know what class SetWindowText() is a member of, but lets say class X. Then:

X * pA[5];
memset(&pA[0], 0, sizeof(X *) * 5);
for (n = 0; n < 5; n++) {
pA[n] = new X;
if (pA[n]) {
pA[n]->SetWindowText("");
}
}



Hope this helps :-)

I haven't had a chance to try the suggestions yet but I think the first post is what I'm looking for.

I am using the pointers for editboxes on a form and thought there might be a better way to clear the editboxes instead of one at a time with the code I submitted.

use like this,
for (i=0;i<4;i++)
{
*(pA + i)->SetWindowText("");
}
