The Opacity property only works for an entire form, not individual controls.
|
|
|
|
|
|
That works in WPF, not Windows Forms. There's a (huge) difference...
|
|
|
|
|
Like I said it was a quick search. Here's a link where WPF is not even mentioned. And it is not easy to do, but I know there is a way since several 3rd party control libraries do support transparent controls:
https://dotnetcentral.net/Weblog/posts/247977.aspx[^]
|
|
|
|
|
Oh I know it can be done, just not without writing your own drawing code for each control you want to be transparent. That's quite a lot of work for something that's rarely a functional requirement.
|
|
|
|
|
True. But in our case we need something wizbang as we are a startup in an established niche industry. Taking advantage of some of the drawing capabilities that a 3rd party library offers gives us a nice visual impact on startup of the app.
Hopefully we will be able to match impact with the rest of the app.

Ok I found I need to use WPF to do this correctly...
However i managed to simulate what I want by doing the following:
Create a tiny fading form with A FormBorderStyle property set to None and a ControlBox property set to False.
When user control is placed on the screen, calculate the position and size and display the fading form on top which fades out of existence and closes.
The only issue is that the current form looses focus - but this isnt too much of a problem as the user control fills out most of the form.

I wonder where Iam going wrong with these codes;
// form1.cs
private void matchbutton_Click(object sender, EventArgs e)
{
string TagNum;
TagNum = InputBox.Text;
string dataqueue;
dataqueue = myRecord.find();
if( TagNum == myRecord.find())
{
OutputBox.AppendText(" Match");
//InputBox.Clear();
}
else
{
OutputBox.AppendText("No Match");
..............................................................
// queue.cs
public Boolean contains()
{
return (find() != null);
}
public string find()
{
queuedata current = first;
while(current !=null && !current.GetType().Equals(this))
current = current.nextdata;
return current.ToString();

Do you think that we are gonna get a dream of problem.
Atleast, explain where and what problem you are facing...
Please remember to rate helpful or unhelpful answers, it lets us and people reading the forums know if our answers are any good.

First of all you should tell us what the code is expected to do and what are the errors you are getting when you run it.
I think you are trying to search for a string in a queue with the code if( TagNum == myRecord.find()).
ok lets see what this find() function does;
it is just a while loop, looping till the end of the queue and it returns when end of the queue is obtained. So it returns null.
|
|
|
|
|
Certainly. I am trying to search for a number in the queue such that if I put that number in a textbox, and click on a match button, a search takes place. If the number is found to be present, then I get a message in my output(a richtextbox) box that the number is indeed present and if not present, I get a message in my output box that the number is actually not among those in the queue.
Thanks

Were you aware that Visual Studio comes with a very capable debugger?

I second that. It is amazing how many people I meet, who are unaware of how capable Visual Studio's debugger. I mean, how hard is it to press F9 on suspect lines of code, and run the damn thing?

Sorry about the harsh criticism there. No comments, hard to read variable names, makes it a tough code review.
When posting code bits on these CP forums, try to utilize the code block button just above the emoticons. Also, just post the code in question. Not the entire thing. Now, in articles on this site, there is the ability to expand/collapse large code block in articles, I wonder if Chris could add such functionality to the forums as well.

Where is the algorithm man? You have posted the whole code.
Post seriously if you want your questions to be answered seriously.
