Hi,
I have VS Studio .NET 2003 Academic. Yesterday, when I select the toolbox option all the tools are now (either) missing or 'grayed out'. How can I fix this? I reinstalled all the disks under the "repair" option, then restarted, but the problem still persists. Also, the project I was working on was a WinForm w/ out much of my own code added.
Please help and thanks for your time.....I'm wasting a lot of mine....
ps- I have also downloaded VS .NET 2005 Enterprise edition.

How can i loop a string in c#? is there any method? (remember its not a string array)
sAqIb
|
|
|
|

You mean to loop the characters in a string?
The string class has an enumerator for the characters, so you can loop the string as if it was an array of characters:
foreach (char ch in daString) {
...
}
---
b { font-weight: normal; }
|
|
|
|

thanks buddy
i found another way to convert a string to characters. its
char[] charArray;
charArray = stringtoConvert.ToCharArray();

Yes, that's how you create a character array from a string. That was not what you asked for, however. 
---
b { font-weight: normal; }
|
|
|
|

There's no need to do that if you just want to loop through the characters. In fact, that requires an extra allocation; so unless you need a seperate array, don't do that. Use foreach like Guffa said:
foreach(char character in myString)
{
...
}
or use a good old for loop:
for(int i = 0; i < myString.Length; i++)
{
char character = myString[i];
...
}

I use a text file to pass command line arguments to a ClickOnce application. My main concern is that if the argument sink fails to delete this file after using the arguments, and no arguments are passed the next time, it will use the previous arguments again.
I am open to suggestions on how to invalidate (expire) the text file somehow.
|
|
|
|
|
How about checking the file creation date against the current date, deleting the file if its "too old" and returning with an error, causing re-reading of the file or prompting the user to restart?
Cheers,
Sebastian

Using the time has crossed my mind. If my loader program names the file using the time, say rounded off to 30 seconds, then the loaded program uses the same algorithm to determine the filename to look for. If the loaded program starts more than 30 seconds after the loader, it will miss the file and show a dialogue to get the required argument.

Hi
I am developing a scripts in C# which can be used to test windows based applications. I use Win32 API's to perform click operations etc. To uniquely identify a control in a window rather than using absolute position of a control I have been using Control-ids and captions of the control. But I found scenarios where the control-id was dynamic and the control didn't have a caption. What I mean by caption is the text of the control. A control, say a button can have both name and text - Name: btnOk and Caption: OK. What I hoping to get is the Name "btnOk" that can uniquely identify it in a window because no two controld can have the same name, but it can have the same caption. I have searched through the Win32 API's and I have been able to find a suitable API that does the job. Any kind of help will be appreciated. Thanks a lot.
with Regards

Hi,
afaik the Handle of each window is unique. Everything (visual) has a handle.
|
|
|
|
|
Thanks mikone for the reply, but I have come across certain Win Forms where the Handle of the control changes each time I call the Application. For eg. I bring up Calculator (here it is same just for eg. sake) each time the handle for the button 7 may not be same. I am not sure if the forms are .NET forms. They could be VC based Win Forms, that is what somebody had told me. Thanks again.
With Regards
Anoop.

I've got a little problem, i've got one threaded class setting up all parameters and finially showing a MSN-Lookalike PopUp window, with a sliding effect. the problem is, the popup only slides 1 or 2px then it gets stuck. Calling the function within the class without using a thread causes no problem and it's shown as it's supposed to. Could anyone help me out or give me a hint ? please 
class PopUpHandler<br />
{<br />
private string popTitle;<br />
private string popContent;<br />
TaskbarNotifier taskbarNotifier;<br />
public PopUpHandler(string strTitle, string strContent)<br />
{<br />
popTitle = strTitle;<br />
popContent = strContent;<br />
Thread popUpThread = new Thread(new ThreadStart(popupShowMessage));<br />
popUpThread.Start();<br />
}<br />
public void popupShowMessage()
{<br />
System.Reflection.Assembly myAssembly = this.GetType().Assembly;<br />
<br />
ResourceManager myManager = new ResourceManager("SystemTray.Form1", myAssembly);<br />
<br />
taskbarNotifier = new TaskbarNotifier();<br />
taskbarNotifier.SetBackgroundBitmap((Bitmap)Properties.Resources.imageSkin, Color.FromArgb(255, 0, 255));<br />
taskbarNotifier.SetCloseBitmap((Bitmap)Properties.Resources.imageClose, Color.FromArgb(255, 0, 255), new Point(127, 8));<br />
taskbarNotifier.TitleRectangle = new Rectangle(40, 9, 80, 25);<br />
taskbarNotifier.ContentRectangle = new Rectangle(8, 41, 133, 68);<br />
taskbarNotifier.Show(popTitle, popContent, 500, 4000, 50);<br />
}<br />
}

I want to create an object. Its background is transparent (it shows underground object). And it shows any Text like Label Control.
How can i do it?
|
|
|
|
|
Derive a class from Label. Put this in the constructor:
SetStyle(ControlStyles.UserPaint | ControlStyles.DoubleBuffer | ControlStyles.AllPaintingInWmPaint | ControlStyles.SupportsTransparentBackColor, true);
You can set the background to Color.Transparent if you like, but it doesn't matter. If you write a Paint handler that renders the text only, you'll have what you want.

If you want a whole form to be transparent (but not its content) you could set its transperency key to a color you will NEVER use for anything else but the forms background color.
<br />
this.BackColor = Color.FromArgb(255,2,3,4);<br />
this.TransparencyKey = Color.FromArgb(255,2,3,4);<br />
this would make the form invisible.
To create transperent controls see the comment before this one

I create a picture. It has an image. And i put a label on it. I want the backcolor of the label is invisible. It shows only text.
In Vb 6.0, i can do it. If i set the label's backcolor is transparent. It doesn't show the backcolor.
Your response doesn't do what i want
|
|
|
|

i understood you correctly. i told you to have a look for the former comment on how to make CONTROLS (like your label) transparent. you have to derive it, add a function call to the constructor and override the onpaint method of the base class.

Keep it in the same thread instead of starting another.
