IL is Intermediate Language, it's the code that compilers targeting the CLR produce - this is what makes the source language unimportant, because they compile down to IL, or to be more specific, MSIL or Microsoft IL, which is just some extensions to the Common IL specification.

I've looked at the Reflector program.

Very interesting.

However, I have found all the draganddrop related classes, except the DoDragDrop.

Am I missing something? It's not in there anywere.

Found it.

Just got lost looking for a method in Form, when it's in Control.

Heath Stewart18-Dec-03 7:30

Wrong one - you must P/Invoke the native DoDragDrop. It is also in there.

Tristan Rhodes18-Dec-03 8:44

I found the one that uses the STGMEDIUM structure you pointed out to me.

Where would the native COM DoDragDrop method be?

System.Windows.Forms.SafeNativeMethods.DoDragDrop. You really should try to P/Invoke these yourself, though, and then compare them to what Microsoft did. It's a much better way to learn about marshaling and Types.

Outlook COM Add-in HOW-TO?

18-Dec-03 13:00

I've always found that, if i have a minimal understanding of something, it is helped more by looking at what others do than blundering around in the dark.

If I know roughly what I am doing, then I am happy to try and find my own way.

I shall look it up as you said, and study it.

Marshaling and Types I already understand, even if it's only rudimetry. What I need to do is study the classes to see what I can do with them.

Thanks again.

I've gone through the magic-eye and slipstick and microsoft tutorials on extending office applications, but I am none the wiser, and hoping someone here can point me in the right direction.

How do I add a menu-option to (say) the Tools menu in Outlook?

I know:
* Its a COM Add-in thing
* I'm using an IDT2Extensibility
* I have to do it in the OnConnection event that is fired

I have found examples and plenty of information about adding buttons, but I really want to add a menu option - either within the Tools menu or via a new top level menu.

Hi,
When I did Copy Text from Word document and I try to paste it into a RichTextBox Control, Text that Contain digit and signs togther are upside down

It go's like this : if in the doc there is text like this "972-363534" when I paste it looks like this "363534-972".

How can I fix this problem by code or some other way?

That is weird! Download http://www.codeproject.com/clipboard/clipspy.asp[^] and see what the clipboard formats that are used are. Post them here and maybe this'll help a bit.

Well I try it and I found that to word copy the data to the clipbord very well , It's the richTextBox that flip the text.
again : I copy this text : 054-363534
and when I paste it into RichTextBox it's look like this: 363534-054

C# Long to C++ Long

Tristan Rhodes17-Dec-03 5:15

17-Dec-03 5:15

What do I use to represent a C++ Long in C#?

I know DWORD is int, and C# Long is not the same as C++ LONG.

C# uses 8 bytes, C++ uses 4.

So what do I do to wrap one to the other?

Thanks

In Visual Basic 6, Integer equals C#'s short, so I think that this may be the case with C++ too (I don't know C++, you see). Thus, int should do the trick.

Actually, be careful with uint. It's not CLS-compliant and you should try to avoid those. I have almost always used int for DWORD with absolutely no problems. Microsoft does the same throughout the BCL, too. While DWORD's can't be negative, the bit representation is still the same so even passing a negative int to a DWORD in some native function works.

as long as it is not publicly accessable, iow locals, private fields.

one should always use the correct type though, although int will probably work 31/32 times Smile | :)

Exactly! Smile | :)

As I was saying, though, this usually isn't a problem. The biggest reason I typically use int is because Microsoft does in their BCL. Since they wrote the .NET Framework, seems reasonable to me. Of course, I guess worrying about CLS-compliancy is pretty moot if you're using a uint to P/Invoke a native call, huh? Poke tongue | ;-P

Search in C# files

Using Windows XP explorer I just tried to search for some words that I know are in comments within some of my .cs files. All the searches turned up empty! I double checked the directory and the spelling. I checked all of the options to be sure case or some other setting was not the issue. Anyone seen this, know why it doesn't work, or what I might be doing wrong?

Check the Index Server catelog, System, to make sure it indexes files with unknown extensions (you can get to this from the Computer Management MMC snap-in, or by right-clicking on My Computer and clicking Manage).

Also, the Index Server does not index files immediately. It catelogs at certain times, usually when your computer is idle. It doesn't happen immediately.

I thought the file searching features were just buggy. I was close to having a hit put out on that little wizard guy and his puppy dog friend Smile | :)

. I had no idea...

I resorted to installing Cygwin32 just so I could use grep.

Any idea how bad the perfomance hit is to have this service constantly indexing all file types (I assume this goes on in the background constantly)?

I, for one, do not think the problem was that the band was down. I think that the problem may have been that there was a Stonehenge monument on the stage that was in danger of being crushed by a dwarf.
