You are assigning myID with the value of 123 in this if statement. Are you sure this is what you want?

well the truth of the matter is that in the end the desired result will be to pull the data from either a db or assign a solid value at a later date, right now i was just trying to get the unit to run.

thanks for the quotes..... that worked.
any ideas on the "Use of unassigned local variable 'myID'" ?

This is because you had declare the variable myID and used it without assigning any value to it such as this

txtbx.Text = myID;

Since myID has not been assigned any value, txtbx.Text would therefore have an unknown value/type which can be dangerous.

If you want to compare a string with a number you should convert the string at first.See the following code :

if(intValue == int.Parse(textBoxText))
{...}

A friend had wrote that you can use the if statement as if (txtbx=="123")... this is axactly true and there is anoher way to convert your variable MyID. you can do it like this:

Convert.ToInt32(txtbx.Text)...

but there is and issue here, at the beginning you must define your variable as integer. if you define a string variable and then if you try to assign it to integer variable you will have the similar problems.

Good Luch on your work. i hope you will be succesfull... Smile | :)

I would like to figure out the best way to add a DatePicker to a webform. I am currently just have a button on the webform. When the button is pressed, I would like the Calendar to popup. I also have the calendar inside of a div. I am not quite sure how to make the calendar show up when the button is clicked.

Try setting the panel's AutoScroll property to true. I hope this helps.

Events when Deleting Tree View Nodes?

11-Jul-05 12:18

I've just been working on a custom multiple select tree control (the ones here at TCP did not satisfy the requirements) and I'm running into a problem. I maintain a hash table of selected nodes and everything is hunky-dory until I start deleting nodes from the underlying TreeView "Nodes" TreeNodeCollection. A client could knock a selected node (node in the selection table) out of that collection and I'd have no way to tell my class to remove the node from the selection table.

Is there some event to listen in on for this? I could write some methods in my custom TreeView class like 'remove node' or something, and make a big note in the comments that future clients need to use that... but that's not good enough for me.

Any suggestions??

Use HttpWebRequest To send POST HTTP request to a web server

hi!
i want to send a POST HTTP Request to a Web Server!

Here i got some information:
http://msdn2.microsoft.com/library/debx8sh9(en-us,vs.80).aspx[^]

my problem is: how can i send such a POST Request, with the JSESSIONID from the GET Response before and the POST Data!?

<br />
POST /webkeeper/Controller HTTP/1.1<br />
Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/x-shockwave-flash, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, application/x-gsarcade-launch, */*<br />
Referer: https://www.myzone.at/webkeeper/Controller?action=Login&brand=myzone<br />
Accept-Language: de-at<br />
Content-Type: application/x-www-form-urlencoded<br />
Accept-Encoding: gzip, deflate<br />

<br />
action=login&login=Anmelden&brand=myzone&username=****&password=****&x=50&y=13<br />

-> the username and password i dont want to show here, thats the reason for the letters: *****

the JSESSIONID i got from a GET HTTP Response:

<br />
HttpWebRequest request1 = (HttpWebRequest)WebRequest.Create("https://www.myzone.at/webkeeper/Controller");<br />
request1.CookieContainer = new CookieContainer();<br />
        <br />
HttpWebResponse response1 = (HttpWebResponse) request1.GetResponse();<br />
response1.Cookies = request1.CookieContainer.GetCookies(request1.RequestUri);<br />
			<br />
Console.WriteLine ("HTTP/" + response1.ProtocolVersion + " " + response1.StatusDescription);<br />
Console.WriteLine (response1.Headers.ToString());<br />
<br />
String sessionid = "Set-Cookie: ";<br />
sessionid += response1.Cookies[0].ToString();<br />

DataGrid cell to span two columns?

Can someone tell me how a cell within a datagrid can be created or modified to span more then one column, like HTML's 'colSpan' ("Column Span")?

Here's what I'm trying to do:

Column Header 1 | Column Header 2
---------------------------------
Data 1 goes here| Data 2 goes here
---------------------------------
Data 3 goes in this wide cell
---------------------------------

Thanx.

I have a small quiz-like thing, with 30 Q's but you only do 10 each time you take the quiz.

So to get random Q's im using Random() and switch().
But you dont want the same Q twice, so i could create a value for every question that changes when the Q is asked, but thats a bit of a pain.

Is there any easyer way to check whether a Q has been asked?

You could do random shuffle with questions, and then use them seqentionaly. This way, you'll get random order and won't ask same question twice.

About that new App.Config

Carl Mercier11-Jul-05 10:30

11-Jul-05 10:30

Hi,

I just started looking at this new typed app.config in Visual Studio 2005 and I must admit I'm very confused. I Googled quite a bit to find more information but could not found anything usable. I have a few questions and I appreciate if some of you could take the time to answer them.

1. How do I encrypt connection strings in Windows Forms apps. I read that it can be done automatically for ASP.NET apps, but this feature seems to have been left out of WinForms. Am I right? Do I need to manually code this or there's an automated way?

2. It seems that the config file is stored in a path that ends with the version number of the application (ie: c:\......\v1.0.0.0). What happens if users upgrade to v1.0.0.1 for example? Will they lose all their settings? How can I prevent this from happening? Can I store my app.configs in a version independent path (user settings and application settings)?

3. How can I access my UI project's settings from class libraries (other assemblies)?

4. How is app.config deployed with ClickOnce?

5. Why is Visual Studio 2005 creating app.configs for all the projects of my solution? It doesn't make sense to me, it should only create one for the UI project. Maybe this is a beta bug?

Thanks a lot for your help and time!

non-rectangular window and wmp control

Member 150930411-Jul-05 9:33

Member 1509304

11-Jul-05 9:33

I've created a non-rectangular windows application and have placed the Windows Media Player control on top of one portion of the form. I have set my transparent color to reflect the color around my non-rectangular background image. When I run my application and set the URL for the WMP control, I do not see the video. If I select the form, then the transparent color is visible. I'm not sure why the redraw doesn't work properly and only screws up if the URL is set for the WMP control. Does anyone have any ideas? Thanks.

CR, LF, and CRLF?

Hello everybody! Big Grin | :-D

OK, simple question here, how do I convert a TXT file that has a line ending of CR or LF to CRLF? I tried reading each line with StreamReader, replacing "\r" or "\n" with "\r\n", and writing the line with StreamWriter.Write(), but it doesn't work! Frown | :(

What else could I try? Thanks! Wink | ;)

Does reading the whole string into memory (using ReadToEnd) and replacing "\r" or "\n" with "\r\n" work?
