Thank You very much Ed. That will get me started. I am sure I will have more questions, but at least now I have a place to begin.
I was trying to read all the choices in the help library prior to asking this question but it is so vast I just kept looking and looking.

I know what you mean, problem is when you have nothing left but looking...

In the Paint event for an application, I have the potential of two different background image properties that are assigned in the application. Each of the background image properties could be assigned to a particular control based upon conditions in the application.
The question is: How do I uncover which background image is assigned to the control and perform a comparison? The code is as follows:
private static void _ctrl_Paint(object sender, PaintEventArgs p)
{
Control ctrl = (Control)sender;
Graphics grfx = p.Graphics;
Rectangle clientRectangle = new Rectangle(0, 0, 50, 100);
string strCardName = ((Control)sender).Name;
string strNewBackPath = "C:/system/formats/" + CardBack.bicycle + ".gif";
System.Drawing.Image imgBackFile = Image.FromFile(strNewBackPath);
string strNewCardPath = LoadCardDeckSelectionFromXMLSettingsXSD(cardPath);
System.Drawing.Image imgCardFile = Image.FromFile(strNewCardPath + strCardName + ".gif");
System.Drawing.Image imgBackgroundImage = ctrl.BackgroundImage;
if (imgBackgroundImage == imgBackFile)
{
p.Graphics.DrawImage(imgBackFile, clientRectangle);
}
else
{
p.Graphics.DrawImage(imgCardFile, clientRectangle);
}
grfx = null;
}
Any suggestions as to how to perform a comparison would be appreciated. The effect observed so far is that the code will always select the else block and will ignore the first block of the if statement.

i don't under stand your problem completely
but if you created a control why don't you create a property which will give a certain value with each picture
for example you have two images which can be chosen for your control take a bool variable assign it true if the image 1 is chosen or false for the other one

I guess what I would need to know is how do I retrieve the path to the background image of the control into a string so that I could perform a comparison between that string path and strNewBackPath? The way the code is currently structured is I am comparing objects which is an inherently flawed idea. That is, as I understand it, one object will invariably be different from another object iteration. Thus, how would I retrieve the background image path as a string so that I could perform the comparison?

when the user browse the image and select it save the path string at that time and use it whenever you want it

The complication with storing the variable name at the time that each of the controls are dynamically created and an image is assigned to each of them is that there would simply be too many variables. What would be really useful is if there would be code such as the following:
string strBackgroundPath = ctrl.BackgroundImage.getPath();
That way I could perform a comparison like so:
if (strBackgroundPath = strNewBackPath)
{
}
...
I do not know which control is being painted at the time it reaches the paint event handler. That is why I would need to be able to retrieve it inside the paint event handler. The only way that I could do it would be to retrieve the path of the ctrl.backgroundimage at that time.
Is there a way to retrieve the background image path as a string from the ctrl.BackgroundImage property?

are you using custom controls then create path property in them
else create a class for which will store your your control name and path and create a method in it which will take the name of control and return the path
or simply store them in array
as far as i know there is no such direct property in most of the control
however picture box do have image location property but i don't think it will gonna help you

Amar:
Yes, I am using a custom control. Perhaps you are right with your suggestion to add a property called path to the control itself which would hold the string value of the path to the background image.
However, it has been some time since I have been exposed to how to extend the properties to a control, and then only in VB. Could you kindly point me toward a C# version of an article for how to extend the property of a control so that when I am in the Paint Event I could do this:
string strBackgroundPath = ctrl.Path;
I would really appreciate a primer on how to extend the properties of a control in C#. Thanks!!!

simple
string path;
public string Path
{
get { return path; }
set { path = value; }
}

Amar:
OK. I did as you had suggested and modifed the control with the extension of the property. At the places where the control is assigned the backgroundimage property, I found the "Path" property as specified. I made the assignment of the backgroundimage value to this new Path property that we added to the customized control.
However, when I attempt to retrieve the value of the path property, it does not show up in the Intellisense drop down list. I should add that the place where I am attempting to retrieve the value from is in a public sealed event handler class. Also, the variables and classes in this sealed class are all implement the static keyword.
The control that is addressed in the Paint event handler of this public sealed event handler class is retrieved utilizing the Control ctrl = ((Control)sender) code, and this ctrl was implemented utilizing the customized control class that was modified to include the Path property. When I remove the "sealed" key word from the event handler class, it still does not show the new Path property.
What are the requirements to enable the Intellisense drop down list to show the property "Path" that we added to the customized control?

I am facing issue that my code executes fine in english environment but not in German and Dutch envionment. I am adding a method in thread pool to run it in async way then I redirect to some other web page. Here what happens in non english env. parent thread terminate before calling async method. Any idea???

You can make the parent thread wait for the thread pool's thread by calling EndInvoke on the delegate instance. Something like
delegate void SomeDelegate();
void SomeMethod()
{
SomeDelegate d = new SomeDelegate(AsyncMethod);
IAsyncResult result = d.BeginInvoke(null,...);
d.EndInvoke(result);
}

Any particular error message? Have you stepped through the debugger to see where it stops exactly?

How can I detect the sound device?
Which "namespace" is required?
and what type is its input and output? is it binary?
Thank you too much.

You'll probably need to go through WMI if you want to enumerate the sound devices. After that I don't know and don't have the time at the moment to look into it.
|
|
|
|
|
Don't know if WMI will be of any help, but in general there are no built-in classes for this in the framework.
You could look into managed DirectX or use p/invoke to call the waveIn*, waveOut* and mixer* functions from winmm.dll.

Hi all dear friends,
I'm looking for how to auto complete login and password field of any win application.
Anyone have idea ?
Thanks in advance...
|
|

Yes, don't do it. Creating this will bypass the basic security of the application.

Hi Edboe.
Your idea produce high sucurity risk, but yo can use the property AutoCompleteSource.
Tip: Use the auto complete only for the username.
SINCERELY.

That's also a security risk. If you use autocomplete, you can see EVERY valid ID in your company, which gives a hacker more information that they could ever imagine. Simply don't do it.

If I want to design an XML editor that has following limited functionalities:
1. Edit XML using tree view and by writing XML code.
2. Validate XML to given XSD or DTD schema.
3. Check Well-formdness of XML Document.
4. View XML similiar to IE browser.
What should i use? A plugin like MSXML parser that has extended abilities to parse XML or it is easy to write code using System.xml ??
please guide me.
Thank you.

It seems fairly simple, and would be a great exercise to learn XML programming.

Is there something you've found lacking in the capabilities of System.Xml? There's an MvpXml library you can check out that has a bit more functionality. I've never seen a need for it though, System.Xml has always had enough power to do what I want.
