hi
i use a requer validator to control a textbox in a web page.
it works correctly on local but when i upload it to server the validator dosnt works.
whats the problem?
thanks

The one time I used validators on a website (which was .NET Beta 2) I had to copy a java script into a very specific location on my webserver (by hand) before things would work.
So much for the much-aclaimed "just xcopy your web now".

The validators use a java script file that must be copied into the IIS website. Copying your application to the webserver does not copy the java script.
It took me a search of my entire machine to find the bloody thing and then I had to have my application crap out doing remote debugging to find out what directory to put the javascript file into.
Does this help clear up the confusion? ie: You have lots of digging searching and debugging to get your validators running.

Hi All,
wie übergibt man eigentlich einen String der Steuerzeichen enthält an eine Oracletabelle, quasi an einen VARCHAR2?
Folgende Source fürht imme rzu einem Fehler, weil auch Steuerzeichen in den Strings HighTeach und LowTeach sein können!
qrystr = "INSERT INTO ruest_teach(RT_RK_ORGE_NR, RT_RK_MODELL_NR, RT_TEACH_H, RT_TEACH_L) VALUES(" + this.RK_ORGE_NR+ ", '" + this.RK_MODELL_NR +"', '" + HighTeach + "', '" + LowTeach + "')";
LG eXi

Hast Du in den Foren schon mal einen anderen deutschsprachigen Artikel gesehen? Bitte halte Dich an die Regeln hier und poste wenn dann in englisch! 
Trotzdem zu Deiner Frage: Such mal nach "parameterized queries", da findest Du, wie es vernünftig gemacht wird.

Hi,
problem is the following:
I have a program sending a ButtonClick Message to another app so that this app opens a modal dialog. To achieve this I use PInvoke and the function SendMessage(hWnd, BM_CLICK, 0, 0). This code works, but when the Button is clicked and the modal dialog opens, my program (the one, which sent the message) stopps running, means no code after calling SendMessage is executed (can clearly see this in the debugger). When I manually close the opened dialog in the other app my program runs on. I can't explain myself this behaviour because all other programs run on properly. For example I could write another program, which runs the code, which should be executed after SendMessage. This program would run without any problems. Can anyone explain this to me? Any solutions to let my program work on?
Thanks

The SendMessage function calls the window procedure for the specified window and does not return until the window procedure has processed the message.
To send a message and return immediately, use the SendMessageCallback or SendNotifyMessage function.

Thanks guys. Don't know why I didn't investigate on that.

Hi
Is it possible to identify the Cursor postion inside the textbox not the mouse pointer.If so how to access that?? Plz Help

TextBox.SelectionStart might be what you're looking for.

I think you can get this information through evaluation of SelectionStart, SelectionLength and SelectedText properties.
MSDN states that if no text is selected in the control, the SelectionStart property indicates the insertion point for new text i.e. the current cursor position. If otherwise something is selected, the cursor position should be the sum of SelectionStart and SelectionLength.
int cursorPos;
if (textbox.SelectedText == string.Empty)
cursorPos = textbox.SelectionStart;
else
cursorPos = textbox.SelectionStart + textbox.SelectionLength;
P.S: All information bases on research in MSDN topics, so the above code snippet isn't tested and comes without warranty

System.Windows.Forms.Form.MousePosition
so from inside the form code :
MousePosition

Hi
That did the job.. but i want to know is it possible to position (move the cursor where i want to move) the cursor inside the textbox thru code.

It's all in the docs:
MSDN topic of SelectionStart states: "You can programmatically move the caret within the text box by setting the SelectionStart to the position within the text box where you want the caret to move to and set the SelectionLength property to a value of zero (0). The text box must have focus in order for the caret to be moved."

Hopefully someone can point me in the right direction...
I need either an algorithm or a component that allows a
program i am writing to have "200 credits" eg: 200 uses.
The credits are activated using a unique code (123456 for
example) but once this code has been used it must not work
again. This way the user purchases a new code each 200 uses
to continue using the software.
Is there an existing algorithm that generates these unique
codes? is there a better way that i should know about?
Any help would be great!

Thanks!
I'll take a look into that, hadnt thought of using a Guid.

> Guid.NewGuid()
I can see how this generates a unique code, thats the first part
of my question sorted.
But lets say i do use a Guid as the code, how is the application
going to know that *i* have generated the Guid and not someone
else?

A questionable approach is by hiding a fake dll in the system, having that hold the serialized GUID (serialized as binary so it is hard to read) and creating a regkey buried in some place like file associations where GUID keys abound. So:
System32: holds syscplgpi.dll which holds your GUID.
FileAssoc: If the regkey exists reduce counter. If counter is 0 del key.
If key does not exist then you are out of credits.
Obfuscation of the data and where you get it is the key. Systems written to monitor system changes during install, after install, and after first execution will expose all of it, though.
You probably want to have a registration key that is generated from a GUID and then you can email both the registration key as well as the GUID value. This way your code can do a recalc to see if you come up with the same registration key. For an algorithm, just convert the letters in a GUID into numbers and fold that value into a smaller number.

Oops -- folding:
Folding is the mathematical art of making a big number small.
If a GUID that is converted to a number ends up being 16 digits long, for example, you can do an algorithm to fold as follows:
Convert.ToString(first 8 digits + last 8 digits).Substring(0,8)
The Substring ensures that if you roll into a 9 digit number you truncate it back into an 8 digit number. While this algorithm is simple, it is not easily recreated by just comparing the result to the GUID.
