Unfortunately there is no way to make a Form semi-transparent and keep controls within it opaque (as far as I know).

The hackery way to do it is to have two forms, one semi-transparent, and the...

Just some quick thoughts, if you are using .NET Framework 2.0 or up then you have the notion of partial classes, which means the code for the Form can be in several different files.

The code you...

Just a quick glance I would play around with this line:

output.Write(fr.friendName, fr.friendStreet, fr.friendCity, fr.friendState, fr.friendZip);

You have to convert the arraylist element into...

Thanks for the input. You gave me an idea and turns out the thing is reversing the string, but not really reversing it.

"hello!?" comes out as "?!hello"

So basically it reverses the order of...

Hello,

I'm having some very confusing problems with the StringFormat class. I'm hoping someone will know what's going on.

I want to draw text right-to-left. It's multiple lines so I figured...

Some interesting answers. I've always used this method:

Single-Instance Application (http://vckicks.110mb.com/single-instance.php)

It's obviously not fool-proof because changing the title of a...

.NET even has a built-in function to do the conversation. Some basic research would tell you the answer

A slightly modified version of Bucket Sort that uses LinkedLists and initializes buckets only when required. Results in massive speed improvements.

depends what you mean by "the icon". If it's just an image try a PictureBox

Convert a color to a uint representation and back with simple byte shifting.

Bucket sort is a very simple, fast sorting algorithm specialized in integers.

perhaps that will get you started

If the angle isn't whole use a decimal point (45.352343). If you want to convert something like 45°30'10'' to a decimal representation then that would be a different function to write.

I tried writing tetris a while back (not for C#) but trust me on this: make blocks classes and then use small arrays to hold 4 blocks in different positions (to make pieces). That will make it MUCH...

I don't mean to give a useless answer but a simple Google search of all the above questions gives immediate and rich answers...

Several ways to do it, here is an article on loading image files (http://vckicks.110mb.com/image-from-file.php). Just make sure to dispose of new objects properly depending on how you load the images

I know what you mean, it would be nice to have a structured way for applications to communicate between each other. The best you will find is by hooking on DLL's used by other programs.

There are...

Try FillRectangle from Graphics class

i would recommond to convert to C# first. Luckily 1.1 to 2.0 C# conversion is relatively simple since most new things in C# 2.0 only make things easier (so worst case C# 1.1 code will be harder than...

There is a series on CodeProject all about this topic, they are quite impressive:

It might not be the cleanest solution, but error when decrypting is almost always the wrong password. It's not too bad to assume that an error meant the incorrect password was entered (error = alert...

I'm not really sure what you mean but here is a good place to start:

They have a lot of articles on custom comboboxes. I don't think you'll find exactly...

I cannot really relate with a personal example. But I can't imagine having to memorize everything.

A better idea would be to memorize Properties and Methods that are commonly used (how do you...

I thought it goes without saying, but add this in the constructor of your Form:

This.FormClosing += new EventHandler(Form1_FormClosing);

I'm not too sure about the EventHandler part, but the...

If you want the border when you print then it's probably easier to add it during the PrintPage event of the document.

try something like this:

for (int i = 0; i < listBox1.Items.Count; i++)

make sure it's i < and not i <= since you are starting with index 0.

Good luck

You need to make use of the FormClosing event. Here is a quick example:

private bool minimize = true;
private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
if (minimize)

This is something similar to what you are doing, working with dynamic controls (http://vckicks.110mb.com/dynamic-control.php).

you might find this page helpful:

Maybe try

this.Controls.IndexOfKey("txt_to" + i.ToString());

if the index is not -1 then you can use this.Controls[i] and it will be the textbox

Calculate the slope between two points.

Calculate the distance between two points.

if you are talking about the default blank row at the bottom of all the rows then you have to turn off the property AllowUserToAddRows.

Since it is not a real row you cannot delete it.

So I took of any Signing, and then I got excited because there was something checked in Security about ClickOnce or something. But neither helped.

Conclusion: It's unsolvable.

I created a new...

I thought about what you said and I'm fairly certain that it was the ClickOnce deployment that seemed to cause the problem. Seems like curiousity killed the cat on this one.

I turned off the...

I've been going crazy with a problem lately and I was hoping someone could give me a little insight.

Basically I have a database project in C# that I work on with two computers. One uses Vista and...

Anyone with the same problem, the recursive scanning (http://vckicks.110mb.com/scan_files.html) article shows how to do it exactly.

Be careful with instances of classes. You might be passing variables to the wrong instance.

A cleaner way to do it is with API calls, there is an example in this page on how to Capture the Screen (http://vckicks.110mb.com/csharp-programming.php).

A simple way to check if the current C# program is the only instance of itself running.
