Has anybody ever drawn the red squigly lines that show up say in Word or other apps under a word when it is misspelled?
I have come up with a way but it is not reliable to underline all words. My method gets messed up with tab chars and also hidden text. I suspect the same would be true for tables and inserted pictures.
Thanks in advance,
Eric

From my knowledge, it is not directly possible to use the rtb class to draw the Office-Style underlines.
However, you can have an effective selection method by saving the selected text and creating custom functions to get text from it - even with hidden text

I think you would probably have to directly draw the lines on the control, either using RichTextBox.CreateGraphis() or by creating a class that inherits from RichTextBox, and overriding RichtextBox.OnPaint

Its possible to draw the line using the approach mentioned. However, the difficulty I'm having is reliably calculating the coordinates of the beginning of the word that needs to be marked with the squiggly.
Any suggestions there?
Thanks again,
Eric

Use the GetPositionFromCharIndex method.

Hi!
The Rich Edit control that's actually the core control underneath the RichTextBox can display underlines (even the squiggly ones), but setting the corresponding character styles is not possible directly with the regular RichTextBox.
You'll have to send EM_SETCHARFORMAT messages to the rtb to enable underlining in a given style. You can't have an underline color that's different from the text foreground color, though.
You might want to look up the CHARFORMAT2 structure in the Platform SDK documentation on the different options you have to underline text within a rich edit control (and thus in a RichTextBox).

Just found out that my statement on the underline color was incorrect.
You CAN have different underline colors, althouth it's not documented in the CHARFORMAT2 struct. The upper 4 bits of the bUnderlineType determine the color.

Hi everyone!!!
I want to add SplashScreen to my application. I found on the Web a source to do : http://www.reflectionit.nl/Splash.aspx
To give more promptness to this SplashScreen, I have to add a Flash 8 control (OCX Flash). There I have problem on execution. The error message :
Impossible to reach a removed object named "SplashForm"
Is there solution!!!

Try making a new project, and copying all your existing source into it

Hi James Gupta and thanx for reply !!!
That what I have done, but there is always same problem !!!
I don't know if you you've seen the code source of the application (URL : http://www.reflectionit.nl/Splash.aspx). The problem is only when I add a Flash OCX control (Flash8.ocx) to the SplashForm  , else, I have not this problem.
Thanx!!!

Hello, does anyone know how to use DrawString / DoubleBuffer / UserPaint / AllPaintingInWmPaint to paint your own RichTextBox? This is for a news ticker that contains multiple fonts, font colors and embedded images. The autoscrolling is working great, but the flicker is really bad and I was told that double buffering is the way to go (is it, or is there something else, like making an image and double buffering its movement??). Any pointers would be really appreciated!

You could override the RichTextBox class, and in the constructor:
<br />
this.SetStyle(ControlStyles.OptimizedDoubleBuffer, true);<br />
this.SetStyle(ControlStyles.AllPaintingInWmPaint, true);<br />

Is it possible to fire two events at the same time?
In my code I fire off an event if my if statement is true (see code below)
<br />
if (SegType == "Y")if(OnQResponse != null) OnQResponse(this, new EventArgs());<br />
Could I add the other event in this statement? Like: if(SegType == "Y") if(OnQResponse != null && OnDataRecvd != null){OnQResponse(this, new EventArg()); OnDataRecvd(this, new EventArg());
Thanks

The only problem I see is your approach, if one of the 2 handlers is null, no event is fired. But that may be the intended behavior. If this is the case, that may confuse other parts of the application expecting to be notified of one event, but are not because nobody subscribed to the other one.
If this is the intended behavior, simply make one event: OnQResponseAndDataRecvd.
if ((segType == "Y") && (OnQResponseAndDataRecvd != null))
{
OnQResponseAndDataRecvd(this, EventArgs.Empty);
}
If you need 2 separate events:
if (segType == "Y")
{
if (OnQResponse != null) OnQResponse(this, EventArgs.Empty);
if (OnDataRecvd != null) OnDataRecvd(this, EventArgs.Empty);
}
You may also notice the use of EventArgs.Empty instead of new EventArgs(). Basically, EventArgs is a class that contains no information, and this way you avoid creating unnecessary new objects.

If you mean that the code handling the two events should execute at the same time, then no.
An event is basically a list of method pointers. When you call the event, it will just call the methods in the list one after the other. That means that when you call OnQResponse, it will not return until all event handlers in it has been executed.

Thanks,
I saw that. I guess there is no way to create a delegate that will fire two at the same time?
Thanks

If you want the delegates to run asynchronously (the closest to firing them at the same time), look for the BeginInvoke[^] method.

Hello everybody.
Does anybody knows a way of changing the color of some words (reserved words) of a code editor using a VS 2003 add-in?
So for some kinds of files, I would like to highlight some words and symbols, check syntax, etc.
I know how to access the TextDocument object that represents the editor, but I don' know which one of its properties should be used to change the color of a portion of text. Any pointers to information on this will be warmly welcome.
Thanks
Omar

How can I update selected row from gridview.
|
|
|
|

Do you think it is possible to give you anything like a decent answer to your question when you have provided so little information on what you want?
The best I can personally do is provide a link to the RowUpdatingEventArgs object[^]

I need to send message from my computer to another with NetMessageBufferSend function. Everything works fine when i'm sending to a computer on the same domain as mine. The problem is that i need to send a message to computer in another domain. Does anyone have experience with this? Any help will be appreciated.

Not supported. This is the function that the command line utility "NET SEND" uses, and therefore, has the same restrictions. You'll either have to change your domain configuration so the target domain trusts the senders domain (not likely to happen), convert your domain environment to Active Directory (also not likely to happen), or use a different messenging system that isn't dependent on Windows Security to work.

These books don't come in an E-Book format and they are NOT free! It's absolutely ridiculous that your asking for them without paying anything.
