Please Help
I want my program be started up with windows.
and user must log in it first before working with any other program

You should be patient and wait for a reply before posting the same question over and over. Thats generally considered rude, and is generally bad netiquett.
You should be able to set your windows form to on-top in its properties in the VS.NET designer. You should also be able to set it to be maximized by default, too.
There isnt any way to prevent a user from ALT-TABbing to another app, though, at least as far as I know. The only thing I know of in windows that prevents someone from using apps or alt-tabbing is the main windows login screen. You might be able to hook into the alt-tabbing process and override it until someone logs in, but you would have to make sure you alert the users of your product that your doing so (leagally, otherwise your app could be considered spyware or a hyjacking program).

What i am trying to do. When a user mouse clicks on a label control, label changes color. If user continues to holds down mouse button and moves over other labels (a click and drag), those labels will change to same color.
How does one detect when the mouse cursor is leaving and entering label controls during a click and drag scenario? I have tried MouseEnter/MouseLeave and DragEnter/DragLeave and the events do not fire when one clicks and drag.
Any suggestions what i should be looking at? I am stumped.
Thanks.

You will need to do a couple things. First, you will need to set .AllowDrop on each label to true, so that they can accept a drop. By default, most controls ignore drops.
Second, you will need to capture the drag action on the source label (the one being dragged) by calling .DoDragDrop (from Control.DoDragDrop), and writing event handlers for DragOver, DragEnter, DragLeave, DragDrop events for each label to accept a drop and respond to it.

Thanks Jon. I was able to figure out drag-and-drop from your hints. I found that drag-and-drop is not giving me the right solution as i had thought. I am going to repost question with a different focus. Thanks for the help.

OK, I have created an AddIN for MS Word, which takes the content of the document, and saves it to a variable...
Microsoft.Office.Interop.Word.Application my_app = (Microsoft.Office.Interop.Word.Application) applicationObject;
Microsoft.Office.Interop.Word.Document my_doc = my_app.ActiveDocument;
my_doc.Select();
my_app.Selection.Copy();
string myText = my_app.Selection.Text;
(the above code works great)
I tried using the Navigate() to send the data to our web application, but I am unable to retrieve it when the Webpage opens:
string strPostData = "SomeData=" + myText;
object strPostHeader = "content-Type:application/x-www-form-urlencode";
string strLocation = "http://mysite.devsite.com/zTest.cfm";
object strTarget = "_BLANK";
System.Object null_obj = 0;
byte[] results;
results = UnicodeToAscii(strPostData);
SHDocVw.InternetExplorer webPost = new SHDocVw.InternetExplorer();
webPost.Navigate(strLocation, ref null_obj, ref strTarget, ref results, ref strPostHeader);
****This is the conversion method*****
public byte[] UnicodeToAscii(string src)
{
int len = src.Length;
byte[] result = new Byte[len + 1];
for (int i = 0; i < len; i++)
result[i] = Convert.ToByte(src[i]);
result[len] = 0;
return result;
}
I keep getting "Argument 4:cannot convert 'ref byte[]' to 'ref object'"
and if I just cast strPostData to an object, the Webpage loads, but nothing is passed in...
Confused? Yes!

Hi All,
I am trying to do the following in a web control that I am creating:
I have a username and password textboxes and a login button.
when the user is in the password textbox and if they hit <enter> I want either one of the following two behaviours to happen:
1. do nothing, or
2. automatically fire the login button's clicked postback event
Right now when a user hits <enter> it loses focus from the textbox and does nothing! (If it is doing a postback then what event is it firing!!!)
This is driving me crazy!
any help would be greatly appreciated!

If you are talking about a C# Windows application then here's an idea, may give you a place to start.
this.txtPassword.KeyPress +=
new System.Windows.Forms.KeyPressEventHandler(this.txtPassword_KeyPress);
.....
private void Generic_KeyPress(object sender,
System.Windows.Forms.KeyPressEventArgs e)
{
if(e.KeyChar == (char)13)
cmdLogin_ButtonClick(this, EventArgs.Empty);
}

Hello folks!
I need an help with the ascii code.
I must convert a number in the corresponding ascii symbol. Now, from the number 32 to the number 127 it works; but after that, it returns sometime the char 'œ' and sometime a strange symbol which doesnt coincide with the one in the ascii table.
How can i solve?
ps: i write the symbol in a textBox if it can help...
Thank You
Enrico

ASCII is a 7 bit code, values 128-255 are undefined in it. There are multiple 8 bit extended ascii encodings. The default in .net is apparently different than the one used in what your reference is erroniously calling ascii. YOu'll need to find the ISO number for the encoding you want and set your app to use it instead.

Can you explain better what u mean for ISO?
I dont know what u are saying...

Bascially a sequence of bytes only makes sense as a text file in connection with a code page (and encoding).
The code page define which character is at which integer position, while the encoding determines how the number is stored in the byte stream. Rememeber that it was only back in the dark ages people thought 256 charactes where enough, so you need a way to store for example character 7625 (what it is I do not know - that depends on the code page).
You mention you use the ASCII table. As correctly pointed out, the ASCII table only defines characters in the range 0-127. So if you have anything in the 128-255 range, it is certain you are not loading ASCII, but something else.
As the .NET framework obviously use Unicode internally (stored in memory with a UTF-16 encoding) it will need to know how to map the byte stream into characters. This is done with an Encoding (see System.Text.Encoding). So with "ISO" in this case is ment you need to know the encoding so you can specify it to the loader.
You can try using the Default encoding - it is the dafault ANSI encoding on the system so it is what outdated programs would use when processing text. While no modern program should touch ANSI encoding with the water from a remote controled fire hose - except when loading outdated dataformats - it is still commonly used, mainly due to ignorance from developers. The ANSI code page can be changed from the control panel, effectively changing the content of all you text files (start to see why no sane person would use it)?
If ANSI does not load, you can try UTF-8 - and if that won't work either you have to find a way of identifying the code page (to use as a parameter in a call to GetEncoding)... You can try loading the file in Word, it tend to give a fairly good guess.

Is there a nice way to do this so I could dynamically resize the leftmost column when a V scroll appears to avoid creating an hscroll bar as well?
Theoretically I could use the Graphics class to measure the string height and use that to compute how many lines would fit, but I'd prefer a more natural solution.

hi all!
i'm new in c# and VS, and i'm working in my university project. i want to do tabbed documents like VS, for that, i use a TabControl but i want that the tabControl has a button in the upper right corner in order to close tabs individually
what shall i do? inherit of tabControl?
create my own control? how?
my witten english isn'y very well, excuse me, i'm spanish
thanks for all!

just put a control where u want it (like a button or image) then when you click it get the selectedTab and set it visible = false; if the tabControl.tabs.count == 0 then set the visiblie = false to the tabcontrol itself
hope that helps

i had in mind something like it...but i want the button is in the upper rigth corner on the TabControl exactly and not in some tabpage or out of tabControl.
i want that it becomes something like the tabbed documents in visual studio.
thanks g00fyman!

can't you just make a user control and put the button in the top right then anchor it to top and right. it wouldn't even need to be a user control

hi to all,
i'm working on a win application with multi document interface (MDI forms).
i have one mdi parent and many mdi child.
in my mdi child i can input some data. i implemented the closing event so if the user hit the cross button in up/right corner i can ask him if he want to save data or cancel the action before exiting the mdi child form. everything is good till now
but if the user the cross button in up/right corner of the parent form, how can i cancel this action, because even if the user say that he wants to cancel the application closes.
does any body have any suggestions
best regards and thanks in advance
fady
