Use the designMode property of the IHTMLDocument2 interface.
Here is some sample code. It assumes that:
1)You have added a reference to mshtml.tlb.
2) You have a WebBrowser control named webBrowser on your form.
IHTMLDocument2 HtmlDoc=(IHTMLDocument2)webBrowser.Document;
HtmlDoc.designMode="On";
And you're set!  Remember that if the user navigates to a new page, the designMode property must be set again.

There's a LOT of code involved in something like this. Check out SharpDevelop[^] for an example.

All I want to do is:
I want to make a win32 DLL that takes two LPWSTR's. One [in], one [out]. That's ALL! The problem is, when I call it from C#, the out string is always unchanged. I know this must be simple to do- interop can't suck this bad. Here is my code:
/// In the DLL:
extern "C" {
__declspec(dllexport) void transformIt(LPWSTR,[out] LPWSTR);
void transformIt(LPWSTR markup,[out] LPWSTR changed) {
changed= L"SOME STUFF";
}
}
// The Interop and the call:
[System.Runtime.InteropServices.DllImportAttribute("mydll.dll")]
private static extern void transformIt(
[MarshalAs(UnmanagedType.LPWStr)] string markup,
[Out,MarshalAs(UnmanagedType.LPWStr)] out string changed) ;
string stuff="wefwefw";
string changed; //also tried string changed="",changed=null, and a StringBuilder
transformIt( stuff, out changed);
Console.WriteLine(" >>>>>>>>>>>>>>> " + changed); //empty
I've tried this with a StringBuilder, I've tried with "ref" instead of an "out". No error is thrown, even when I do a try catch block. I know it's finding the DLL ok, becaause I made another test method that just returns an int and it worked. why why why why why why why
Please tell me it's me that sucks and not interop.

Have you tested your DLL in a non .Net environment? Maybe something is just not right with the DLL.
|
|
|

Well like I say, I tried making a simple function that just returns an int, in the same dll, and calling that from dot net and it worked fine.
Hey can you tell me if I'm assigning the LPWSTR properly? Do I have to do like memory alloc or something, or make a char array? The compiler didn't throw any errors..
thanks

It never gets called!?
If I override a label control then its OnPaint is getting called but not for a textbox, why is it so?
|
|
|
|

Some of the .net controls are drawn directly by windows and bypass the .net events. Override the WndProc function and handle thw WM_whatever you need there. Make sure you pass any messages you don't want to the base WndProc function. I had to do this on a toolbar.

I have various custom controls derived from UserControl that appear in modal forms. Within Dialogs the arrow keys are an alternate form of tab control i.e they move to the next control in the direction of the arrow within the current container ( this is standard windows behaviour I think ).
The trouble is I want to be able to respond to arrow keys in one of these controls. No key event is generated ( or sent to me ). Even overriding WndProc and checking for WM_ messages that way doesn't work.
I notice that list boxes etc are able to get these key events.
Any ideas ?

Hi Everyone,
Question: How would I test if someone was holding control while they pressed enter in a textbox?
I'm currently doing this:
int nReturn = Keys::Return;
int nControl = Keys::Control;
int nData = nReturn + nControl;
if (e->KeyData == nData) Now this code works, but you have to press enter twice while you're holding down control. Does anyone know why? Am I doing something wrong in the code? Another quick question, how would I do all code in one if condition? I tried:
if (e->KeyValue == Keys::Return & Keys::Control) but get this warning:
warning C4806: '&' : unsafe operation: no value of type 'bool' promoted to type 'int' can equal the given constant if I put brackets around Keys::Return & Keys::Control it gets rid of the waring, but it still doesn't execute the code in the if block.
I know my code is in MC++, but if you could help (just give your response in C#) it would be very appreciated.
Thanks!

Use the BitWise OR operator ('|') not AND ('&')
<a TITLE="See my user info" href=http:

Now that I think about it that makes a lot more sense. It works now, but I still have to press enter twice for it to actually go into the correct block. Any idea's on that?
Thanks!

How do I convert a double value to an byte array (byte[8]) and the reverse from byte array till a double value?
In C++ we may take a memcpy to an char array and cast the array to a float!

Take a look at Convert class, especially ChangeType method.

Hello Gurus,
I've been searching for the common icons such as CLOSE, CANCEL, SAVE, CLEAR, NEW, DELETE, Etc... But no luck. Do you know where I can find them?
Thanks again

They are not stored as icons, but are stored as bitmaps.
You can create a simple single or multiple document project using the wizard and then copy them from the toolbar resouce.
OR TRY
C:\Program Files\Microsoft Visual Studio\Common\Graphics\Bitmaps
Where there are bitmaps for the items you listed in more than 1 directory.
Trust in the code Luke. Yea right!

That's very helpful! Thank you very much, John.
