I was wondering if anyone know where I can get a webpage control. I.E. a viewer control that will display a webpage ( I believe VB had something like this at one point).

Thanks,

You can host IE as a control.

Problems using context menu on a Datagrid

I right click on a selected datagrid cell and my context menu does NOT display. However, if I right-click on a non selected field I DO get my context menu? How can I fix that.

I used SPY++ and noticed that right-clicked on a selected cell is different then clicking on an unselected cell.

HELP WTF | :WTF:

System::Void contextMenu_Popup(System::Object * sender, System::EventArgs * e) {
MenuItem* menuItem1 = new MenuItem(S"&Match");
this->contextMenu->MenuItems->Clear();
this->contextMenu->MenuItems->Add(menuItem1);
}

TIA,

How can I do that, in C++?
I heard I had to use a API, but I don't even know what that is...
I just need a simple function that replaces or adds a key to the registry, can anyone help me with this?

Hi, I found the following link
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vcmex/html/vcconaddingmctoexistingapplication.asp[^]

for Adding Support for Managed Extensions for C++ to an Existing Application.
To modify the project settings
I followed the following steps.

1)Open the target project in Visual Studio.
2)In Solution Explorer, right-click the project node and click Properties.
The Property Pages dialog box appears.
3)In the left pane, click the C/C++ folder.
4)Click the General folder under C/C++.
Set the Compile As Managed property to Assembly Support (/clr).

However, I dont' see (Step 4) Compile As Managed property at all in my C/C++ folder.
Why is it? Is it because of my software? I'm using Visual Studio Version 7.1.3088.

Thank you

Basically, all you need to do is set the compiler option to /clr. You can do that by opening the Command Line folder under the C/C++ Folder located in your project property sheet, as you mentioned above. Then, just add the compiler switch to the list.

I want to wait unti the text appears on the screen before calling DoPrntScreen:
How can this be handled easily?
void CWaterHammer::OnBnClickedPrint()

CPrntScreen * ScrCap;
ScrCap = new CPrntScreen();
m_caveat="This publication is intended for use as a piping system guide. It should not be used in place of a professional engineer’s judgment or advice and it is not intended as installation instructions. ";

CEdit* pCEditBox = (CEdit*)this->GetDlgItem(IDC_EDIT2);
pCEditBox->SetWindowText(m_caveat);

delete ScrCap;

Cicking anywhere in Dialog Box closes Dialog

I have created several layers of dialog boxes using MFC C++ .Net. However, I do not want to automatically go back to calling dialog when I hit return anywhere in the active dialog. I want to just be able to click on OK button to do this.
I have the OK button as not the Default button, but clicking anywhere in Dialog box always closes the active Dialog Box and goes back to calling Dialog box. Is there a fix?

The setting the OK button to not be default will take care of the hitting return for you, but I am not sure why you would be seeing the dialog close on a mouse click on the dialog. Can you paste some of your code for the disappearing dialog so that we can see it? If not, feel free to email it to me to look over really quick.

Not on a click of the mouse, but a on return.
This is disastrous to client entering data and loosing it because they hit enter/return instead of tabbing to next field.

Simple Datagrid needs

I want to do a simple datagrid. No database, just some data. Specifically I would like to display a 2 dimensional array of integers. Or a 2 dimensional array of strings.

Could someone help me?

I have searched the web sites, and they all give wonderful, but convoluted examples.

TIA

You can always use a list control, with columns (remember to set it in details mode).

I know that Java and HTML can be linked.

'FILETIME': ambiguous symbol

Anonymous29-Jan-05 0:30

I want to play sound using winapi, so I wrote these lines of code:-

-------------------------------------------------------------------------------------------------------------------
using namespace System;
using namespace System::Runtime::InteropServices;

namespace WavAPI
{
[DllImport("winmm.dll")]
extern "C" bool sndPlaySound(String* lpszSound, unsigned int fuSound);
}
-------------------------------------------------------------------------------------------------------------------

But I got "FILETIME: ambiguous symbol" when I compiled, because FILETIME is both the member of InteropService namespace and defined in WinDef.h.

I tried to use #undef FILETIME, but it didn't work. How can I solve this problem? Or is there another way to play sound from API?

You could, instead of using the,
#include "windows.h"
line at the beginning of your code, use fully qualified names everywhere in your application. If it's a large and complex program, however, you will probably hate this suggestion.

Quoted from message:

#include "windows.h"
line at the beginning of your code, use fully qualified names everywhere in your application. If it's a large and complex program, however, you will probably hate this suggestion.

I ran into this same situation when I needed to make a direct call to the Win32 API. The problem was that it was necessary to add using namespace System::Runtime::InteropServices to get the DllImport attribute to work. There was no way to use a "fully qualified" name. My code was not referencing "FILETIME" anywhere in the application. It was a conflict between a symbol defined in the Win32 API header files and one defined in the System::Runtime::InteropServices namespace. After some searching around on the 'net as well as some experimentation, I came with the solution I posted immediatly in reply to the original poster in this thread, and it seemed to fix the problem.

Before the using namespace lines, insert #include<windows.h>.

That should get rid of the "ambiguous symbol" error.

However, if you than get anything such as "CreateDirectoryA is not part of System::IO" type errors (as I gotten when I encountered this same situation), then immediatly after the #include <windows.h> line, add any necessary #undef's, such as #undef CreateDirectory in my case.

Thus, your example would look as follows:

<br />
#include <windows.h><br />
<br />
// add any necessary "#undef"'s if any "<symbol> <br />
// not part of <namespace>" errors.<br />
<br />
using namespace System;<br />
using namespace System::Runtime::InteropServices;<br />
<br />
namespace WavAPI<br />
{<br />
[DllImport("winmm.dll")]<br />
extern "C" bool sndPlaySound(String* lpszSound, unsigned int fuSound);<br />
}

That should hopefully "fix" the problem.
