When you say "It didn't work" what did happen?
An Exception?
Nothing on the display?
Your computer burst into flames?

I've built hardware destroyers into embedded code before - if the software believes the hardware has been copied and the firmware pirated, it blows the PSU, and anything else it can get it's hands on. One of our asian distributors and a paraniod MD prompted that one...

I did something less severe several years ago. A company I worked for that I didn't completely trust used some software that I wrote in my own time that they relied on. I knew they wouldn't pay me for it (I was right) but it made my life so much easier whilst I was there so I permitted it's use making sure the T&Cs stated clearly that only I had the right to use the application at anytime and it was owned by me.
I wrote a 'bomb' in it that corrupted the exe if I didn't log on for a certain period. All the data that was used however (the data is of course their property) was placed at this point in unencrypted text files so they could access it but could no longer process it using *my* software.
After we inevitably parted company, the software went 'boom' atfter the expected ammount of time  I pointed them to the text files when they rang to ask WTF and told them to go **** themselves. One of the highlights of my life

there's no data in the listbox that it supposed to show.

In that case, since it appears to be in your form constructor:
public frmMainForm()
{
...
}I assume that
if (prog == "CS") is failing - presumably because "prog" is not "CS" yet.
Where are you assigning that?
Have you put a breakpoint at the if statement, and looked as what "prog" is?

I declared the variable prog as global and used it to assign the value "CS" when the user has clicked the radio button. it is goes like this:
private void rdioProgCS_CheckedChanged(object sender, EventArgs e)
{
prog = "CS";
rdioProgCS.Enabled = false;
rdioProgIT.Enabled = false;
}
|
|
|
|
|
So since your code that tests it is in your constructor it will not be equal to "CS" until after the form is displayed...
By that time, it is too late, the constructor is only run once per instance.

ok. i understand now. i'll just transfer the code to a method (which didn't occured to me a while ago). what i first thought is if i put the code inside the method of the listbox the database will be opened once i clicked the listbox and since i need the data to be in the listbox before i click the listbox it will be too late so i put it in the constructor which i think is the best place because once the method of the form has ran the database will be open until i close the form.

i dont know but if you put break point and detecting the code.

Hi all,

if is a integer. . . .
How do i type it?
txt_number.Text =
Thank You

it is in string form you can do anything with it
{maybe Session["Product_Name"]=null}

You can type it like that:
txt_number.Text = Session["Product_Number"].ToString();
|
|
|
|
|
it state:
Object reference not set to an instance of an object.

For my first answer i asumed that you have already added a Session variable of type int with name Product_Number. The point is that you can use ToString() method to get a string representation of your variable which is a numeric type.
Here is a full example:
Session["Product_Number"] = 555;
string s = Session["Product_Number"].ToString();

Now you have it
Forgive my sarcasm but put the question too.
Don't make us search for it. You posted it in the QuickAnswers/Questions.
Post it here too.
Also what exactly do you want?
Your question is really vague.

Is Global Assembly Cache similar to COM?
It seems you register objects which can be used by other applications. Other applications can then create objects by referencing the GAC?
|
|
|
|

COM is a technology. GAC is a location. COM registration is a lot more involved, with entries in the registry, etc. GAC is a common location to place assemblies, there is no registration or entries in the registry.
I know the language. I've read a book. - _Madmatt

ok so does it make sense to use COM in C# applications?
|
|
|
|
|
Well that depends.
Do you need to expose you assemblies to/as COM?
In other words is there a "legacy" COM based component(s) that needs to use your C#/.Net
data/object model?
If yes => then YES it makes sence to expose your "whatever" as COMVisible.
Else => NO it does NOT make sence.

ok so if I had developed in .NET a bunch of data access helper classes for a particular type of database and wanted it used by other .NET applications, each application would need the DLL right?
If I had an application in C++ MFC that could use that code, it may make sense to make it COMVisible and then the C++ application could get at the methods?
