Converting data from TextBox (String^) to string

[iMikki]

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 , 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.

Try adding this line -

using namespace System::Runtime::InteropServices;

Is there any other known way to get text out such TextBox into a string? One made by Microsoft themselves? :p

You have typed in Marsh**e**l. The correct spelling is Marsh**a**l. Do you see the difference?

How strange - because I copied it directly from your post - since first of all I hate typing and secondly its always better to copy paste :p But it is working now - let me test the output etc. Thanks in advance <3

:thumbsup: But I really think you should not be driving now. :)

No Im not driving lol. It works! *cheering the hell outta it* Adding text to the TextBox and with a button its sending the data to my vector string which can be read and send to the output :-\ Thank you very very much! I really needed this line! <33 :rose:
