Hi All
**********Programmin Challenge**************
I am developing a desktop application in C#.Net which opens
another form of an unmanaged application. The WinForm(of unmanaged application) has number of controls on it .Textbox has a focus when application starts.I just want to focus on the third control which is a button by programmatically pressing the tab key
SendKeys.SendWait(Keys.Tab.ToString()); //for taking focus on second control
SendKeys.SendWait(Keys.Tab.ToString());
//for taking focus on the desired button which has a tabindex=2(0,1,2)ie third control
It is not taking the focus from the textbox to the button but instead typing in the textbox "Tab".
Thanks in advance

If you have created an application which uses database, and installed it for your client. Next you have updated the application and updating the database structure. So the client's database and the newest database has different structure. What is the ideal way to update the database structure, and still using client's previous entered data. I use C#.

This has been discussed a lot; it's a common scenario. Here's a thread on the MSDN forums that discuss dealing with SQL schema changes from the C# side of things.

I'm currently creating an application that reads the structures of old and new database, creates insert query and executes it to the new database from C# application. This means I have to executes lots of rows. I'm looking for a better way if any.

Where can I find sample codes showing implementation of Monte Carlo rabin_karp search NOT just a pseudocode.
Thanks

What? Honestly, this is one of the strangest sounding questions I've heard in the last 4 years in this forum.
A google search for monte carlo rabin_karp doesn't produce any results.
Can you explain what it is? Then maybe we can help you.

This is a pseudocode for Monte Carlo rabin_karp algorithm.
Input Parameters: p,t
Output Parameters: None;
Mc_rabin_karp_search(p,t)
{
m = p.length
n = t.length
q = randomly chosen prime number less than mn2
r = 2 ^(m-1) mod q //computation of initial remainders
f[0]=0
pfinger = 0
for j = 0 to m-1
{
f[0] = 2*f[0]+t[j] mod q
pfinger = 2*pfinger + p[j]mod q
}
i = 0;
while(i + m<=n)
{
if ( f[i] = = pfinger)
println (“Match at position”+i)
f[i + 1] = 2*(f[i] – r*t[i]) + t[i+m]mod q
i = i +1
}
}
What am seeking is a sample of a working code to help me understand it actual implementation.
Thanks

I would suggest trying the Mathematics and Algorithms forumn. I'm sure somebody on there might know what you talking about.

Are you saying you are unable to turn that pseudo code into a method? Maybe you should consider changing occupations. I'll pay you $50 to mow my yard.

Hi Guys,
I am working on a console app which telnets to a linux server. Now this linux server ask for a username and password which i try to send via my code. Now everything works up until the SendKeys.SendWait() - it seems that the window does not react to the "Enter" command. I have tested this with some other telnet servers, which are not linux and they work. Any help or if any other work around are available I am open for anything.
My issue is - I have a system built by ADP and would like to grab data from them and put it into my on db to process. However, their system is closed and the solution I came up with is to screen scrape what I need. If you guys know something alredy out there or can point in the write direction it would be great.
Thanks ahead of time.
public string Login(string Username,string Password,int LoginTimeOutMs)
{
int oldTimeOutMs = TimeOutMs;
TimeOutMs = LoginTimeOutMs;
string s = Read();
while(s == "" )
s = Read();
Console.Write(s);
if (!s.TrimEnd().EndsWith(":"))
throw new Exception("Failed to connect : no login prompt");
Console.Write(Username);
SendKeys.SendWait("{ENTER}");

Not sure I can help, but I wrote a telnet client to do similar stuff (connect to a SCO UNIX box and manipulate a third-party character-based application). I had to create a script language for it. A Windows Service would cobble up the necessary script and run it.
A sample script to log onto a server, execute ps -a, and disconnect:
<login:
@someserver
<Password:
>myusername
<TERM
>mypassword
<$
>
>ps -a
$exit
The important bits are:
System.Net.Sockets.TcpClient
System.Net.Sockets.NetworkStream
Anyway, I didn't use SendKeys, I simply used Read and Write on the stream.
I would have written an article on it, but the handling of telnet options isn't quite right.

I am working on a similar project. (ADP) I have some code that may work for you. I am also having an issue. My problem is I have a form with a textbox and a button. I need to be able to fill out the textbox push the button and send the textbox string to the telnet-console application to perform the task. I have built the form and have found code for the telnet-console application. I can logon successfully and perform a download with the telnet-console code. My problem is having the form communicate and trigger the telnet-console application. I would appreciate any help you could give.
Thank you,
GerosDS

Hello
I'm looking for a good tutorial about user control
I need to learn the purpose (I have an idea) and how to design it
Thank you for your suggestions / Help

If that tutorial was not good enough for you, what sort of tutorial are you looking for?
Why is common sense not common?

It's a joke ?
I make severall search here
Nothing interesting pop-up
I've tried :

tutorials i dont know (tell me if you find a good one), but i ussually use usercontrol to fill up form like pages, that way i avoid creating many forms, you may try that later on.
About using usercontrols for creating buttons, i never needed so far, but there are here in codeproject article that teach you how to create a particular usercontrol like a button or a combobox or a calendar, better you download one of those!
keyword: create usercontrol button calendar

trying to help & get help

Thank you nelsonpaixao
Yest I need a complex control to provide address searching
A feew combo, textbox etc
Not a simple button
I will continue to investigate how to do it well

You don't really need a tutorial, just have a go!
1. Create a test winforms app, right click and choose Add|User Control.
2. Handle any events from the controls just like you would in a form.
3. If you need to override any of the built in methods so it reacts externally in a different way then use the override keyword to override any of the base's virtual methods.
4. You can create your own properties, methods and events. If any conflict with the base's ones and they're not overridable, use the new keyword or rename your own to avoid the conflict.
That's about it really. By deriving from UserControl (or Control or Component) MS have already done the hard work for you.
