hello folks!
I'm new in c++ and I'm trying to write a c++ jpeg edge detector for linux, but I have some problems with the pixel matrix that I must use to apply the prewitt mask...
can somebody help me? how can I get one pixel grey level? how can I copy this to a matrix?
Here is my code:

Hello,
Can I use the Windows Image Acquisition automation layer with MC++? I have looked for an answer everywhere, but could not find one. If the answer is yes, does anyone know of any good tutorials for MC++ and WIA?
Thanks, Roy

found it out -> yes it can here is a sample of the code to setup a webcam...
//Main Windows Image Acquisition Variables
WiaVideoClass* wiaVideo = new WiaVideoClass();
ItemClass* item;
String* selectedID;
WiaClass* wiaManager = new WiaClass();
CollectionClass* wiaObjects;
//Device specific variables
Object* device;
String* devName; //holds the name of the device
* * *
//Finds the WIA device
for(int i = 0; i < wiaManager->Devices->Count; i++)
{
//loads the wia information from the devices in the wiaManager into wiaObjects so the
// devices can be accessed
wiaObjects = dynamic_cast<collectionclass*>(wiaManager->Devices);
//accesses one of the wia deceives in the wiaObjects variable
device = wiaObjects->get_Item(i);
//passes the device by reference to wiaManager to create the WIA item
// this return value of the created item is type casted from ItemClass to item
item = dynamic_cast<itemclass*>(wiaManager->Create(&device));
//gets the device info in the object datatype and returns it, it is typecasted to a string
selectedID = dynamic_cast<string*>(item->GetPropById( (WiaItemPropertyId) WiaDeviceInfoPropertyId::DeviceInfoDevId ));
//get the webcam name
devName = dynamic_cast<string*>(item->GetPropById( (WiaItemPropertyId) WiaDeviceInfoPropertyId::DeviceInfoDevName ));
}
//some standard error messages / protection from crashing
if(selectedID == "")
{
//problem
}
else
{
//no problem
}

i forgot, make sure you reference the window image acquisition com and the wia video com too

I am just starting to learn C++ and I need help with line code that will produce an animated bitmap. I've tried several tutorials from this website and none of them would even compile. I'm using the free BloodShed Dev-C++ Version 4.9.9.0 that I downloaded from www.download.com
I'm into learning not stealing, so if you have a little time to show me a few genereic codes that I can use that would be great.
wow. this is the coolest of the cool.....est.

Does BLOODSHED support MFC. 
I think only SDK is supported by Blood.

I have loaded image (DDB) using GDI funcs and ZOOMING in and out using stretchblt funcn with memory as source and window screen as destination. while zooming in i am invalidating the screen area with third param set as false and hence able to achieve flicker free image but how to do low flicker (if possible no flicker ) for zoom out.
also please tell me if i can directly write on to the vdu buffer and freeze the client area until the write on buffer is complete
Thankyou

I use VS NET 2003 and loading windows form app for debugging is so slow compared to just fo example VC++ MFC apps, moreover if you while debugging and single steping thru the code inadvertantly point mouse pointer to Form->Text to find out what's the caption it hangs itself down completely?
This is the process for loading dll's after being pressed F5:
Does it really needs so many dll's?

It shoud be: this->Text

Thanks, but I change form caption in thread to which I pass pointer of the form created it.
So in VS2005 it is loaded as faster as normal mfc projects in VS2003?

I have old computer, so i don't know if it is that fast, but comparet MC++ built by VS2003 and VS2005. When i try to run in debugging VS2003 took me about 30 sec, in VS2005 took me abaout 2-6 sec.
If you only try to run, then you can press CTRL+F5

Hi
I try to deepen my knowledge in Visual C++.net..
Up to now I'm always using c#.
So I try to port a C# application to Visual C++.net.
But it break down on a Byte Array.. In c#... no problem..
Here a little bit from the # App..
<br />
byte[] buffer = new byte[1024];<br />
<br />
for(int x = 0; x < 6; x++)<br />
{<br />
buffer[count++] = 0xFF;<br />
}<br />
<br />
for(int i = 0; i < 16; i++)<br />
{<br />
int tmp = 0;<br />
<br />
for(int y = 0; y < 6; y++)<br />
{<br />
buffer[count++] = Byte.Parse(mac.Substring(tmp,2),System.Globalization.NumberStyles.HexNumber);<br />
tmp = tmp+2;<br />
}<br />
}<br />
<br />
client.Send(buffer,1024);<br />
And now the c++ complement..
<br />
<br />
<br />
for(int x = 0; x < 6; x++)<br />
{<br />
buffer[count++] = 0xFF;<br />
}<br />
<br />
for(int i = 0; i < 16; i++)<br />
{<br />
int tmp = 0;<br />
<br />
for(int y = 0; y < 6; y++)<br />
{<br />
buffer[count++] = Byte::Parse(mac->Substring(tmp,2),System::Globalization::NumberStyles::HexNumber);<br />
tmp = tmp+2;<br />
}<br />
}<br />
<br />
client->Send(buffer,1024);<br />
I don't know how to work with this array... I searched google for so long..
I know in Visual Studio 2005 there are some language alterations for c++..

Use the array template (or generic, I don't know) class.
array<byte> ^buffer = gcnew array<byte>();

Thank You
But how can I bind this class into my project?
It throws the following errors...

Oops, I forgot to check the "Do not treat < as tags" checkbox. The post should look like
"Use the array template (or generic, I don't know) class."
array<byte> ^buffer = gcnew array<byte>[10];

OK, I have been developing an interface for editing records in our database.
I want to set it up as a control that I can use in other applications I
build. I am using databinding to tie the fields to my controls, such as
labels and textboxes.
I can create a solution for a stand alone application that runs like I want,
but whenever I create a solution for a control, then none of my data shows
up. I have tried making C++ controls (the language I am familiar with) and
VB and even C#. I get the same result: The interface compiles and displays
as designed, but no data.
When I add the control to the toolbox, I get the control plus a dataset and
adapter, but no databinding control.

Can anyone point me to any articles regarding creating user controls in managed C++? I am interested in reading about how to "subclass" the controls in C++ .NET so they have custom appearance/behavior. I've tried googling but either there is very little out there or I am googling the wrong keywords.
Thanks
Why is common sense not common?
Never argue with an idiot. They will drag you down to their level where they are an expert.
