This must be switch (c) without the ;
I also believe that it must actually be switch (*c)

Thanks, I just changed and it fixed that part.

I think you should read very carefully a syntax reference of the C programming language.

I am only trying to follow a flow chart given and it is very confusing. Thank you

While following the flow, you shouldn't forget there is also the syntax...

I am stuck with this section of my code so far: error codes: expected int and got pointer to int and operands of = illegaltype pointer to int and int
void DrillOneProb (int*c, int*r1, int*r2)
{
int CorAns,
Reply;
{
printf("\nWhat is %d",r1); 1st error scanf("%d", r1);
r1 = 2 + rand() % 11; 2nd error
}

The above steps, however just fix compiler errors...I don't know if the semantic will be correct.
BTW what about a good C language programming book?

switch (c)
{ (states that this is illegal type pointer to int in switch expression.)
case '1':
printf("+");
CorAns = r1 + r2; (operands of + have illegal of 'pointer to int' and 'pointer to int')
break;

The real solution, however, would be reading the f*#?n' book.

I do not believe that has been in any of the chapters that we have read so far, but I will look again at the latest chapter because each assignment is associated with that chapter.

I am developing an application with three splitter panes, leftpane,right pane and bottom pane.
leftpane consists of a tree control, by clicking on the tree item, correspoding Dialog displayes in the right pane. For one tree item, by selecting it , i need to display another application by running winExec(), in right pane. I am facing problem at fitting this result application in the rightpane..I have tried with variuos Show window parameter for Winexec() call, but i failed.
thanks,
hema.

WinExec() spawns a new process.
If you want to show that in another application you need to create a relationship between the two applications.
You can do that using SetParent[^] and then use MoveWindow[^] to place it correctly in the right pane.

thanks for the reply..I will try it today..thanks a lot.

Hello people,
I am trying to make an application with in- and output. Input by textboxes and output by writing it to a file.
I succeeded to get text from a TextBox^ and put it in a RichTextBox^. No problem.
I succeeded to use fstream to 'print' data (string) to a file.
Now I want to combine these by using a vector<string>.
The problem I am facing is that if I do: fout << textBox->Text; that I get the following error:
1< d:\stageappvc\terminalapp\terminalapp\Form1.h(185) : error C2679: binary '<<' : no operator found which takes a right-hand operand of type 'System::String ^' (or there is no acceptable conversion)
1< C:\Program Files\Microsoft Visual Studio 9.0\VC\include\ostream(653): could be 'std::basic_ostream<_Elem,_Traits> &std::operator <<<char,std::char_traits<char>>(std::basic_ostream<_Elem,_Traits> &,const char *)
If I want to write the
textBox->Text to my vector. I get the following error:
1>d:\stageappvc\terminalapp\terminalapp\Form1.h(194) : error C2664: 'std::vector<_Ty>::push_back' : cannot convert parameter 1 from 'System::String ^' to 'const std::string &'
I tried to find out what this String^ actually is - but I could not find an accurate answer. I also tried:
textBox->Text.toString() which failed too.
Is anyone able to help me with this? I tried to find examples of how to put TextBox data in a string, but I couldn't find anything useful...
Kind regards,
Mikki Weesenaar

Don't use "System::String" instead use "std::string"

I have:
std::vector<string> textCode;
private: System::Windows::Forms::RichTextBox^ textBox;
private: System::Windows::Forms::TextBox^ invoerVeld;
textBox->Text += invoerVeld->Text + "\r\n"; < works fine
textCode.push_back(textBox->Text); < no-go
textCode.push_back(invoerVeld->Text);
1>d:\stageappvc\terminalapp\terminalapp\Form1.h(194) : error C2664: 'std::vector<_Ty>::push_back' : cannot convert parameter 1 from 'System::String ^' to 'const std::string &'
1>d:\stageappvc\terminalapp\terminalapp\Form1.h(195) : error C2664: 'std::vector<_Ty>::push_back' : cannot convert parameter 1 from 'System::String ^' to 'const std::string &'
So I think I cannot just use string in stead of String. Its a native thing of the TextBox and RichTextBox. I guess... Or if Im wrong, correct me

I got this from MSDN -
String^ c = gcnew String("Change Me");
std::string str1 = (const char*)(Marshal::StringToHGlobalAnsi(s)).ToPointer();
std::wstring str2 = (const wchar_t*)(Marshal::StringToHGlobalUni(s)).ToPointer();
|
|
|
|
|
I dont see the relation between the first line and the other two.
And I need it otherwise.
I have a String^ (coming from textBox->Text) and I want to store this in a string (which I have in a vector).
|
|
|
|
|
The first line creates a String^. I believe you already have that in textBox->Text.
The second line converts that to a string.
The third line converts that to a wstring.
What else do you not see?
|
|

|

I guess I need the second then.
Currently I have
std::string str1 = (const char*)(Marshel::StringToHGlobalAnsi(textBox->Text)).ToPointer();
But it gives me the following errors:
1>d:\stageappvc\terminalapp\terminalapp\Form1.h(200) : error C2653: 'Marshel' : is not a class or namespace name
1>d:\stageappvc\terminalapp\terminalapp\Form1.h(200) : error C2228: left of '.ToPointer' must have class/struct/union
1> type is ''unknown-type''
1>d:\stageappvc\terminalapp\terminalapp\Form1.h(200) : error C3861: 'StringToHGlobalAnsi': identifier not found
So I tried to #include <marshal>, but that didn't work either.
How can I use this function?
And by the way - thanks for your fast replies

Typo
It should be Marshal.
You got it wrong there.
Look at my posting.

1>d:\stageappvc\terminalapp\terminalapp\Form1.h(7) : fatal error C1083: Cannot open include file: 'Marshal': No such file or directory
:p Yeh - I corrected it but copied the wrong stuff I saw...
But with A its still not working 
I am using Visual C++ Express Edition. Downloaded the package yesterday :p
|

I suspect some mix-up in your code.
You do not have to include any file called Marshal.
And you can use this class only in managed applications.
