If a forms property ShowInTaskBar is set to true then yes, most applications have a window in the taskbar. You can make the taskbar window for your application 'flash' by using the API commands FlashWindow and FlashWindowEx. You can learn more about these commands by googling the application API Guide and API Viewer. I also have code for this in VC#, but at the moment I am not at the right computer.

iam working in c# i need some thing like module in vb to write public variable that keep it's value in it during project running and can call it from any form
is there thing like it in c#

Use a static class to accomplish this. The MSDN documentation has some good examples of how to do this:

i am currently a developer that uses .net as my main programming environment. and i wanted to know how could i use .net to create License and then in turn use them to protect the applications that i have developed?

can some one please point me into the right direction? posible some tutorials or papers on how i can use .net to implement this????

Hi all,

I need to delete rows from my db, when the criteria is: older than a
certain date.
Can it be done without an SQL string query?? Using only a DataSet
and/or DataAdapter?

The regular SQL would be: "DELETE FROM EventLog WHERE
EL_TimeStamp<01/08/2006".
But the problem is using the date in C# and Access-database.

Thanks in advance,
Danny

Have you tried using a parameterized query?

DateTime dt = DateTime.Parse("01/08/2006"); // be careful about the current culture here, may want to specify
OledbCommand cmd = new OleDbCommand "DELETE FROM EventLog WHERE EL_TimeStamp < ?;", connection);
cmd.Parameters.Add("@p1", OledbType.Date,dt);
cmd.Execute();

Hello fellow programmers,

I have something in mind which, as far as my knowledge goes, cannot be done.
But I'm writing here to ask for a solution...

I'll start with explaining a class I wrote, named ShapedForm...
ShapedForm inherits from System.Windows.Forms.Form.
It has a built in functionallity to receive a Bitmap object, and change the form's region according to the drawing in the Bitmap, leaving out "transparent pixels".
I've also added a mouse-drag ability, as it's impossible to move the form without a title-bar.

So today I've started coding a new project, where I wanted a shaped button!
My idea was to inherit System.Windows.Forms.Control which, as you all know, is the base class for many controls, and add the above functionallities to it.
The problem comes here...
Is there any way to force the derived classes (i.e. Form, Button, Panel, etc.) to inherit from my ShapedControl instead of the original Control class?
Kind of like overriding an inheritance or something like that...

Again, as far as I know, it cannot be done...
So if you have an alternative method in mind, please share it with me. Smile | :)

Thanks in advance,
Shy.

You are right, you cannot do that. What I would probably do is design it this way:

I'd create a number of Shaped... classes, e.g. ShapedButton, ShapedPanel, etc. These would inherit from the various based classes (Button, Panel, etc.)

The "Shaped" functionality would go into a separate class of its own that contains the functionality that you need. Then from the various control subclasses you created earlier you would call into the Shaped class.

e.g.

public class ShapedStrategy
{
    public void SomeShapedFunctionality(Control shapedControl)
    {
        // Do stuff.
    }
}
 
public class ShapedButton : Button
{
    private ShapedStrategy shapedStrategy;
 
    public override void OnPaint()
    {
        shapedStrategy.ShapedPaint(this);
    }
}

Hopefully that might give you some ideas.

Yes... I have thought about it...
But it's kind of annoying to do that with every control...

Hello, my first post here.
Gonna try and be specific as possible.
Here's the situation. I have a small app with a list View set to Largeicon view.
The problem is it will display the icons on some computers, but not all.
Works fine on my laptop, but not on my desktop... Both computers are running WinXP, all
updates and patchs installed.
So I'm just looking for some pointers on where to start looking for the problem.
I know this sounds vague, but it's the best I can do for the moment.

hope someone has an idea...

Thanks alot

Cross my heart, smack me dead...stick a lobster on my head.

Not sure if this will help, because I've never heard of a case exactly like this, but what about the color depths for your desktop and laptop machine?
Could this have anything to do with your problem?

Did you try on a third computer as well?

What kind of graphics card do you have in your desktop pc? Are the drivers up to date?

Hello again..

Desktop colour depths are both at 32bits,
and the graphic card is a Radeon 9600XT 256.

I guess this is weird eh?

Yes it is.
Sorry, don't have an idea what could cause this. Did you try different color depths for you ImageList?

Hi!

Just wanted to let you know that I just discovered one of my computers showing the same effect.
I stumbled over it while trying to modify the zone security settings.
The icons you usually see for "My Computer", "Local Intranet" and so on are not being displayed.

I don't know when the effect started or if it's there from the start. My graphics card, unlike yours, is a Nvidia 7900 GTX, so it's pretty unlikely that it's a graphics driver problem...

I have several textboxes that I wish to toggle the readonly attribute true/false by the user cliucking a button.

Can this be done in VS2005 and if so, how?

-- modified at 9:34 Saturday 5th August, 2006

Sure. Create an event handler for the button's clck event and inside to the following for each textbox:

this.textBoxXX.ReadOnly = !this.textBoxXX.ReadOnly;

Thank you.

It's little snippets like these that make life much easier Big Grin | :-D

.

Is there a website out there where you can do a search on these things. I hunted for hours without any luck.

Once again, thanks.

How about MSDN ?
You will find everything there.

The problem is finding it. Frown | :(

As a learner, one of the biggest problems I have is using (and therefor searching for) the right terminology.

Often someone will help me out with at least a partly constructive response that may point to where I can search. Therefor, whilst in this case the response was an obvious one liner, many others have helped me to find in depth explanations by giving me the right terms to look for.

In this instance I searched high and low for what I wanted to do (and in doing so I have bookmarked many related web pages for future reference) including MSDN/MSDN2 without success. You may be interested to know that the search/how to/contents functions are excellent tools that I use frequently from the help menu on VS2005. Suspicious | :suss:

Additionally, MSDN is not always helpful when it comes to providing real world experiences and examples. Whilst I can often find highly technical Confused | :confused:

(to me anyhow) references, they often lead me to more confusion than I had in the beginning.

These message boards provide an excellent means of surrogate tutors especially to people like myself who live in remote country areas where few people care little more than if it's going to be a wet or dry season, let alone the intricacies of a computer that can change something by itself as in my original question.

I presume you well know the answer to the ULTIMATE question ie What is the meaning of life? I also presume that knowing the answer indicates that you have sufficient intelligence to understand the bigger picture.

I unfortunately cannot agree with your comments as I have discovered at least 6 other web sites solely devoted to the topic of my interest and which presumably are frequented by people like myself.

Is this messageboard moderated? What is the meaning of lfe?

Having said the above, I'm not to sure how to end this response so I will just use a term that has come to mean a lot to me:

break;
Poke tongue | ;-P

PS: No doubt that in 2 years from now when someone searches the ms.supernetv3.7 (ms replacement for the then outdated internet) they too will be able to find this post listed under "What is the meaning of life" but unfortunately they will definitely not be getting the answer they are seeking Sigh | :sigh:

What is the simplest way to serialize a class into a string?

i.e. something like that:

object o = new Something();
String s = SerializeToString(o);
// ... two month later, pasadena, california.
object o = Deserialize(s);

-- modified at 9:14 Saturday 5th August, 2006: note to self - markup is messageboard specific!

We are a big screwed up dysfunctional psychotic happy family - some more screwed up, others more happy, but everybody's psychotic joint venture definition of CP

Tree<t> in C# || Fold With Us! || sighist

The SerializeToString method could XML-serialize the class, and the Deserialize method could deserializer it using the XmlSerializer class. The resulting XML document could be read in as a string, thus giving you a string-serialized object.
