In the System::Collections::Generic namespace, there is a doubly linked list called LinkList. However, as far as I know, you have to write your own sort.

3. Write a program which outputs frequency of digits in a given integer. For example, if the number is 12424329, output will be
Number Frequency
1 (space) 1
2 (space) 3
3 (space) 1
4 (space) 2
9 (space) 1

Use a switch statement to obtain frequency of the digits.

This means nothing (space) i just put in so the numbers would line up

By the time I saw this, you had failed your assignment. One would hope that you learned from this to do your own work, instead of drinking and posting the question online at the last minute. If you do try to do your own homework in future, you'll find we'd love to help if you get stuck. Just not when you post a (trivial) question and show no sign of having made any attempt to solve it.

Hi all,

I have a form that contains one button and one textbox, the textbox will take a number that will be passed to another form. I have done this successfully.
The thing is that I need the second form to create a number of pictureboxes = the number received from the first form.

Any ideas?

call:

gcnew PictureBox()

for each. Then set the Image and other properties as desired.

Hi kilroytrout,

I have done this in the Form_load as follows:

<br />
pictureBoxX = gcnew System::Windows::Forms::PictureBox();<br />
pictureBoxX->Location = System::Drawing::Point(24, 262);<br />
pictureBoxX->Name = L"pictureBoxX";<br />
pictureBoxX->Size = System::Drawing::Size(45, 49);<br />
pictureBoxX->SizeMode = System::Windows::Forms::PictureBoxSizeMode::Zoom;<br />
pictureBoxX->Image = Drawing::Image::FromFile("avg.jpg");

but nothing appears in the form Confused | :confused:

Did you add each PictureBox to the form's control collection?

form->Controls->Add(pictureBoxX);

You want source code in C++/CI ? What do you mean by digitalizing ? I have an article on this site for capturing images from a Canon camera, and a series on image processing. They are in C#, but you can obviously call those from C++/CLI ( but not from C++ )

GetClusterInformation is not working

Hi,

I am trying to get the Cluster version and vendor id installed in the current machine.

I am using GetClusterInformation API for this...but i am getting "unhandled exception " problem for this..Please help me this.
Thanks in advacnce.

part of the code:

const int BufferLength=55345;
char Namme[BufferLength];
DWORD length = BufferLength;
LPCLUSTERVERSIONINFO lpClusterInfo;
lpClusterInfo->dwVersionInfoSize=sizeof(CLUSTERVERSIONINFO);
DWORD retVal = GetClusterInformation(cluster, name, &length, lpClusterInfo);

if i am using only GetClusterInformation(cluster, name, &length, NULL); this gives me the name of the cluster correctly.

You are using uninitialized pointer.
You need to modify to ,

CLUSTERVERSIONINFO ClusterInfo;
ClusterInfo.dwVersionInfoSize=sizeof(CLUSTERVERSIONINFO); 
DWORD retVal = GetClusterInformation(cluster, name, &length, &ClusterInfo);

p.s. Please read forum guidelines, such questions should be asked in VC++ forum.

Come on !
Pointer needs to point some thing valid. Here , you have just declared it, and not initialized with any CLUSTERVERSIONINFO address.

You don't have access to obtain information on every process on your system. If you run the following code, you may get an access violation:

array< Process^ >^ processes = Process::GetProcesses();

for each (Process^ process in processes)
{
	Console::WriteLine(L"{0}: Started {1}", 
		process->ProcessName ,process->StartTime);
}
