Hello!
Is there any possybility or chance to transfer a MFC-Program into SUSE Linux?
Or exist tools? Thank you for help.

No. There are a number of portable windowing toolkits (wmWindows springs to mind), but I don't believe MFC has been ported to Linux. It would be a big job, how would you go about making sure you leaked as much memory as MFC does ?

perhaps i should write it. I'm getting pretty good at leaking memory.

check if it works with Wine

some guys managed to get Microsoft word, excell, powerpoint,
outlook, explorer, access, visio etc running in Linux

How do you capture a VK_CONTROL + 'A' (for example the select all key strokes) with out using the Accelerator??
|
|
|
|
|
I would capture the 'A' or 'a' key, then use GetAsyncKeyState to find out if Control is down. Be careful - the high bit tells you if it is down now or not, the rest tells you if it's been down since the last time you called it. So you need to either make sure you check the right thing, or call it twice to be sure.

It seems that if the VK_CONTROL key is down, I cant receive any other WM_KEYDOWN messages except for the first key pressed.. I have a function to see if the VK_CONTROL is pressed down but it still seems to block all other msg's.. I have tried to catch the combos in WM_KEYDOWN and in WindowProc. Do I need to catch the WM_KEYDOWN for the control key and catch a WM_KEYUP message for the 'A'? If I use the GetAsyncKeyState where should I call it?
|

|

I'm sure I've done it in WM_CHAR with something like this
switch(nChar) // I can't recall where I'd get this from
{
case 'A':
case 'a':
GetAsyncKeyState(VK_CONTROL);
if (GetAsyncKeyState(VK_CONTROL))
{
// Control is down
}
else
{
}
}

Hi,
I am creating a program that will make a graphic of a math function, but I have a problem with the LineTo function, I have to remake it, but not as:
LineTo(int x, int y) { dc.LineTo(x,y); }
but as a cycle of SetPixel.
The reason of this is because for finding the roots of the math function I need to know where the line I draw passes through the X Axis, or where y = 0.
My question is how do I write a variant of LineTo where I use SetPixel, instead of LineTo???
Thank you very much.
you can contact me on e-mail blackkattle@abv.bg

If I understood it right, you want to determine, prior to drawing it, at which x does a segment intersect the x axis (if it does): this can be done with a little of trivial algebra, no need to draw the line pixel by pixel. So, this function determines whether a given segment crosses the x axis, and, if so, changes its end point so that the segment ends precisely on the intersection:
bool adjust_to_x_axis(int x0,int y0,&int x1,&int y1)
{
if(x0==x1){
if(y0<=0){
if(y1>=0){
y1=0;
return true;
}
else return false;
}
else if(y1<=0){
if(y0>=0){
y1=0;
return true;
}
else return false;
}
}
int x_int=x0-y0*(x1-x0)/(y1-y0);
if(x0<x1){
if(x0<=x_int&&x_int<=x1){
x1=x_int;
y1=0;
return true;
}
else return false;
}
else if(x0>=x_int&&x_int>=x1){
x1=x_int;
y1=0;
return true;
}
else return false;
}

if (y1==y0) then the line never cross the x-axis, otherwise x = x1 - y1*(x1-x0)/(y1-y0).

The solution is x=x0-y0*(x1-x0)/(y1-y0), not exactly what you wrote. Also, the code considers whether the given segment (not the whole line) intersects the x axis.

Actually x0-y0*(x1-x0)/(y1-y0) = x1-y1*(x1-x0)/(y1-y0) = (x0y1-x1y0)/(y1-y0).

You don't have to. Just plug in your drawing (SetPixel) backend callback to LineDDA.

hello,
i need a matrix!!! but i have no const int values. my values are all int (because the values changed inside the programm). is there a possibility to make a two dimensional array (int array[n][m]) without const int values????

You must have one of the dimentions fixed, i bealive 
use the operator "new"

You can possibly try a vector inside a vector, or a list of vectors, but your going to need VC++ 7, as I think templated templates are new to VC++.
Then again you could try Perl. It lets you do it.

No, you can do a vector of vectors in VC6.

Didn't know that. For some reason, I though template templates where new to VC7.
Thanks.;)

in VC++ 6 I've used vector of vectors (and even more!), like this:
#typedef std::vector<string> StringVector;
#typedef std::vector<stringvector> StringMatrix;
and it works

What makes you think they need to be constant values ? Or do you mean for the dimensions ?
Do this:
int ** ppInt = new int[nRows];
for (int i = 0; i < nRows; ++i)
ppInt[i] = new int[nCols];
Now you can reference each element as ppInt[x][y] ( unless I got rows and columns the wrong way around, which I am want to do ).
As has been said, a vector of vectors is a better solution in terms of memory management, but if it were me, I'd probaby write a matrix class which wraps a int ** and does common matrix manipulations for me. Or search the web for one.

thanks for reply.
yes, you are right, i mean the dimensions as constant values.
my compiler has problems with int ** ppInt = new int[nRows];.
error: int* cannot convert in int**
and with ppInt[i] = new int[nCols];.
error: int* cannot convert in int
what´s wrong?
nRows and nCols are integers in my program.

MFC is the Best wrote:
ppInt[i] = new int[nCols];.
try
ppInt[i] = new int*[ncols];

I need to display XML ( heirarchical view ) like in IE in a Edit box .
I am using the XML DOM mechanism to extract XML from the xml file .
the XMLnode->xml returns the XML string to me .
When i display it now I get text which doesnt look pretty .
as for eg I should get
<parent>
<child1>hello
<child2>hello2
all i get now is
<parent><child1>hello<child2>hello2
Please if anyone knows a better Control or Method of displaying this lemme know !
