Hi All
My application (C#, Framework 1.1) running in the background. I am displaying a form in every five minutes. This form has only a hyperlink control. To show myForm I am using
myForm.ShowDialog();
When this form is displayed, it grabs the focus, and I loose the focus if I am working in another application, say, MS-Word. My form has the following properties set.
myForm.TopMost = false;
myForm.FormBorderStyle = FormBorderStyle.None;
How can prevent this from happening?
Can anybody help me on this?
Thanks
Muthu.

Hi,
My issue is I want to show the form..I don't want to hide it. When I am showing that form..it should not get any focus. The work being done in other applications should not be interrupted.
Thanks
Muthu.

Why are you using ShowDialog() instead of Show() ?
ShowDialog() makes the form the top window for that application (as with modal
dialogs, the onces you can not ignore inside an application),
whereas Show() is used normally for forms and for modeless dialogs (the ones you
can leave open but still allow you to operate other windows).

Because I am calling ShowDialog() in a Thread. If I use Show(), it gives a weird look, and controls in the second form not diplayed and grayed.
Thanks
Muthu.

When I insert a char in textBox, the program will fall because that variable inserted in the textBox must to be integer.
How to fix this.

I don't understand what you mean by that. You can use the TextBox.Text property to set its text to a string.

The text inserted in the textBox must be integer. But if I enter something else............. Problem.

So do you mean you want to prevent the user from entering anything but integers into the TextBox? If so, you may want to use a MaskedTextBox[^].

Yes. But how to do that, because I have Visual Studio 2003.
Help.

Not really. That just means your client application was able to successfully request the SMTP server to deliver the message.

You can not get any delivery status for a mail when you send it, as it is not delivered directly to the recipient. You only know if it got delivered to your outgoing mail server.
You can never ever be certain if a mail was delivered or not. The closest you can get is if you include a request for a receipt in the mail, then the receiving mail program may attempt to send a receipt back to you when the user opens it.
If the mail could not be delivered, the mail server may attempt to send an error report to the mail address that you supplied as sender. In some cases, for example if the mail was filtered out as spam, it will not send any error report.

Actually you can get a bit closer than that if you're sending html email, the recipient's client displays images, and you have a webserver. Embed a link to an image on your webserver with a unique identifier in the URL, if the image is ever accessed the email was displayed.

That is an alternative, but I'm not certain that it is any closer. The recipient may choose not to display images in mails, just as s/he can choose not to send any receipt.

Greetings all. I'm writing a performance test harness for a system that uses the System.Collections.Generics.Dictionary to contain some rather large collections of things, and I'd like to pick a random entry from these dictionaries and do something with it. The key and values cannot be easily produced randomly, so my best bet is to randomize an int between 0 and dict.Count, and then pull the entry. Obviously this would work fine with a Hashtable, since it has an integer indexer.
But I can't find any way to kludge an int indexer into a Dictionary that isn't a performance pig (which kind of distorts my performance test results). For example, my current (Uggh) code does this:
dictKeyType[] dictKeys = new dictKeyType[dict.Count];<br />
dict.Keys.CopyTo(dictKeys, 0);<br />
<br />
int idx = GetRandomInt(dictKeys.Length - 1);<br />
dictKeyType randomKey = dictKeys[idx];<br />
but obviously for large amounts of data, the array copy is going to distort both time and memory use. The distortion in memory use can be avoided by doing a foreach loop through the keys while decrementing the randomInt and then taking the value when you hit zero... but man, wouldn't it be better to just have an int indexer on the Dictionary (or Keys)?
Anyone have an idea on this? Or have I just missed something immensely simple?

Can you use Dictionary.KeyCollection.Count?

I use the count to do the upper bound on the random number, but I can't use it to index into the Dictionary.

Sorry, I misunderstood. I see your quandary.

Hi,
you could:
1. collect all (or a significant range of) key values in a new collection (e.g. ArrayList)
2. randomly pick one out there and search your dictionary for it.
Even when the dictionary evolves, there is probably no need to repeat step 1
all the time in order to perform performance tests...

I have been considering something slightly different, but along these lines, which is to build a schedule of actions and store them in a list, and then run through the list of stored actions.
Sure would be nice to have the equivalent of an array subscript into the dictionary or key colleciton, tho.

OK this is I need to do.
1. How to insert picture in RTB ?
2. How to print in WSISYG manner RTB?
I know regular way of printing is to open StringBuilder&StringWriter, etc. Which work fine for flat text.
But overall I believe I need to specify one printFont at end of this method and that is all... not what I want.
What if I want to print document with pictures and lot's of different fonts (multipage...). Is there some better way to do this?
Thanks!!!
