How can I draw zigzag red lines under some words in a RichTextBox or any other textual environment? (Just like what is done in spell checkers)
Don't forget, that's Persian Gulf not Arabian gulf!

I create a MDI contain form, add a MainMenu, a ImageList, a ToolBar, and the ToolBar relate the ImageList.
When I use the function Application.EnableVisualStyles() to enable xp style, the toolbar icons are disappeared. But when I use instead of a manifest file, the toolbar icons display correct.
Is this a bug with .net framwork 1.1?
(I used VS.net2003 simplified chinese version)

Does anyone know if it is possible to give the ComboBox control a flat appearance? If not, do you know where I may find a flat combo box?

Anything's possible (given time)! 
Search for the author "Carlos H. Perez". He has some great flat controls available here on CP.

Yeah, I noticed that just today. I remember him saying that he was moving everything new to a commercial library. Nice of him to pull the old stuff!  Greedy bastard.

I can get the form's graphics with CreateGraphics(). But how can I get the title bar's graphics? or How to determine the title bar's retangle?
The wParam gotten from WM_NCPAINT always is 1.

Ok, I am trying to figure out the best way to do this. I have string representing an HTML page that I need to render and then save as a .jpg or .gif image. I currently use the IE control to preview the HTML page, but I need to be able to capture an image without previewing the document. Any pointers or ideas?

I'm currently working on a project where I need to scrape a web page for info.
Seems pretty simple far. The problem is that the site has a password protected front end. When you log in it takes you to a menu page. The data I want to scrape is on another inside the site.
The question is after making my initial webrequest and posting data to the stream, how to I navigate to another page and then do a request for it's data.
Thanks in advance

Are you using the WebClient class? Does the site use cookies to store session data? If so, make sure to set it up to receive those cookies.
|
|
|
|

I solved this.
I am using HttpWebRequest and HttpWebResponse. I created a CookieContainer to hold all the session stuff from the first request which is the login page.
I can now copy that Cookie container into the CookieContainer of any new request that I want to make on the site.
HttpWebRequest loginRequest = null;
HttpWebRequest secondPageRequest = null;
loginRequest = (HttpWebRequest)WebRequest.Create(loginURL);
secondPageRequest = (HttpWebRequest)WebRequest.Create(secondPageURL);
CookieContainer loginCookies = new CookieContainter();
loginCookies = loginRequest.CookieContainer;
secondPageRequest.CookieContainer = loginCookies;
Thanks

Heath Stewart kindly provided me with the code snippet below which works generally for exposing functionality that somebody's wrapper of a windows system control left out.
My question now is, how do i best integrate it with VS Designer? The textbook way is to create a new component TreeViewNoHScroll. I am then free to register the class in the designer toolbox etc. But that seems a bit heavy, adding my own Windows Forms control dll to the toolbox for every simple wrapper patch. At the other extreme, I could directly edit the designer code where it creates the new TreeView() and make it a new TreeViewNoHScroll, but I dont like to muck with designer generated code because i have a hard enough time replacing controls or properties that somehow get lost and dealing with other designer quirks and gremlins.
So, is there a way to dynamically create a TreeViewNoHScroll that inherits from the existing instance of a designed TreeView, before the window is created? Or to somehow use reflection to just replace the protected function in TreeView without even creating a new wrapper class?
What's the best way to fix the wrapper with minimal impact on the designer? Thanks in advance for any suggestions.
// Exposing functionality from under a Wrapper, courtesy Heath Stewart
private const int TVS_NOSCROLL = 0x8000;
protected override CreateParams CreateParams
{
get
{
CreateParams ret = base.CreateParams;
ret.Style |= TVS_NOSCROLL;
return ret;
}
}

You could put the create params in an enum and create a new control from the treeview
TreeViewEx or something and expose the parameters as a property
You can then set the property to noscroll for the implementation you want, instead of hard coding the create params. This also gives you a treeview which you can add extra properties later when you need them.

yeah, that's the solution i was trying to avoid, the TreeViewNoHScroll control. anyway maybe like you suggest it's the best way, and does have the plus of being the place to put in any other mods to TreeView.
Any way to deal with the downsides i perceive:
-- another file in the project
-- registering the control with the toolbox (which sometimes forgets which of my controls are registered anyway)
-- is it possible that TreeView will ever be changed and break my code.
Thanks in advance!

I'm working on my own XmlSerializer/deserializer class, and while developing the deserializer, I've noticed that Type.GetType("System.Drawing.Color") is returning null instead of a Type object. What's the reason for that? I don't see an explanation in the documentation, and I can do Type.GetType("System.Double") fine, so it's not an issue with ValueType objects... Perhaps it's an issue with structs for some other reason?
Thanks,
Arun

It expects the FULLY QUALIFIED NAME (iow assembly name, ver , etc, public key).
Rather use typeof(Color) or recursive thru the loaded assemblies.

Ah, okay, that must be it, thanks! System.Drawing.Color is not in my assembly or mscorlib.dll, it's in System.Drawing.dll.
I guess I'll iterate over loaded assemblies and see if they have the type I'm looking for.
|
|
|
|
|
You don't need to iterate... you know it belongs in System.Drawing.
Assembly a = Assembly.LoadWithPartialName("System.Drawing");
Type t = a.GetType("System.Drawing.Color");
...will do the job
|
|
|
|
|
Hmm, yes, but can I generalize that for other times and other assemblies? I'd hope also that it wouldn't actually reload the already-loaded assembly.
Thanks,
Arun

It wont reload it (unless u have changed it of course).

Good to know that it's implemented smartly!
I'm still not sure I can generalize across types. Perhaps I can for the types I use presently, but maybe not in the future. That is, I'd rather not store the assembly name (partial or full) in my file, especially since LoadWithPartialName isn't preferable for long-term, according to documentation.

i started learning c# because i had a nice idea about to write a program for windows and its my first time i program for windows so i wanted to learn the latest technology , which seems c#+forms, i started learning and it was really good nice language and seems fun and simple.
i learned the basics and all was well , but then i decided to learn the stuff i needed for my idea , and i needed midi api, i looked everywhere and i couldnt find it !!.
apparently there is no midi support in c# (i dont mean play a .midi file, i need full control over the notes and everything).i checked managed directx and nothing there too !! , i got really upset.
the only thing left to do that i can think of is code the midi with c++/unmanaged directx into a dll and use it with my c#/forms UI.
since i have no experience with dll's, and mixing managed/unmanaged code what i need is tutorials and maybe some examples how to do it.and if mixing unmanaged directx is a problem?

You know, I'm almost thinking about writing a .NET/DirectX tutorial...
Anyways, until I work up the motivation to do so, have you tried using the Managed DirectX libraries? Go to the DirectX portion of MSDN and look for the Managed DirectX 9 SDK.
Not a in-depth music programmer myself (I do graphics), but that may help you out.

hi
This is great news, i really love to read a tutorial, cant wait.
well, before i learned c# i wrote a nice music program for my engineering project, using very complex algorithm to synthesize many notes from a single note. since i needed to write a program that uses this algorithm, i wrote a windows application with c++ & directx , i used directsound to play the notes , and to learn more directx i also wrote my own gui using direct3d.
what im trying to say is that i know directx a little, and i learned c#+forms because i wanted to start learning standart gui's with the latest technology, to develop a newer simpler version of my university project , dropping the directx gui to write simple window's gui, and dropping the complex algorithm for simple midi, this will allow me to extend the programm really simple and fast.
the first this i checked is managed directx, and to my surprize microsoft did something strange, the added directDraw and removed directmusic. so no midi in managed directx
this is too long but i hope to give you motivation for the tutorial.

hi
i dont know if you looked at my replay on the forum , so here's the link

i really hope you will write a .net/directX tutorial , no need for fancy stuff , just teach how to combine the two together will be great
