Also, you have to make sure that the StartPosition property is set to Manual for the form.

Hello, here are some beginners questions
First, how do i get a form to return a value? If i allow the user to select something, like a object of some kind, how do i return this object to the class that called the form?
Secondly, how do i determine if a class fulfills a certain interface?
To clarify this question, i have this function that loads DLL:s but theese contain many classes, and i wont it only to load those classes that implements the IMyForm interface, please advice
private Form loadPlugIns(String dllName) {<br />
try<br />
{<br />
Assembly MyAssembly = Assembly.LoadFrom(dllName);<br />
Type[] Types = MyAssembly.GetTypes();<br />
<br />
foreach (Type oType in Types)<br />
{<br />
try<br />
{<br />
if ((oType.IsClass == true))<br />
{ <br />
object ibaseObject = Activator.CreateInstance(oType);<br />
Form form;<br />
form = (Form)oType.InvokeMember("getForm", BindingFlags.Default | BindingFlags.InvokeMethod,<br />
null, ibaseObject, null);<br />
return form;<br />
}<br />
} catch (Exception ex)<br />
{<br />
VirheHallinta.LogException("Failed to load module.", ex);<br />
}<br />
}<br />
return null;<br />
} catch (Exception ex)<br />
{<br />
System.Windows.Forms.MessageBox.Show(ex.ToString());<br />
return null;<br />
}<br />
}
Hm, looks awfull (my code) in the window...

Hi,
1. There are several prossibilities.
a) Show the Form as you would normally with ShowDialog and add a property to it so the result can be retrieved afterwards. This is like the built in dialogs of .Net work.
b) Define your own ShowXY function in your form which internally calls ShowDialog on himself and returns the wanted result:
public MyObject ShowMyForm(){
if (this.ShowDialog() == DialogResult.Ok)
return _myResult;
else
return null;
}
2. There are several way to do this. One is:
if (Array.IndexOf(t.GetInterfaces(), typeof(IMyInterface)) >= 0)
Console.WriteLine("Interface implemented");
else
Console.WriteLine("Interface not implemented");

Can forms return a value to, let's say the winmain function, or can something like SendMessage be used to send s message to another window's callback function? If so how?

Hi all,
I've created a service that needs to log in a different log then the application log. Therefor I've added the following line of code:
System.Diagnostics.EventLog.CreateEventSource("ServiceOne", "ServiceOneLog");
But when I run the InstallUtil I can see that it automatically adds the eventsource in the application log.
Does anybody have an idea how to make sure that my logs are put in ServiceOneLog? Or is there a way to tell the InstallUtil to which Log he needs to add the source?
Thanks in advance,
Geert

Hi all,
I'm trying to select a tab from the windows form's standard tab control on right clicking of mouse button.
The mouse event args gives me the location of the mouse pointer.
But the tab control doesn't expose any method or property to get the tab on which my mouse
pointer is hovering.
Has anyone of you faced similar problem like this ? Or atleast it will be nice if anyone can show me a pointer towards solving this problem.
Hoping to hear from you guys...
Thanks and regards,

You might try this approach...
You can get the coordinates of each tab on the DrawItem event. If you could save those locations and sizes of each tab every time the tab control is drawn, then in the mousedown event you can identify which tab was clicked on by referring to your saved information.
Good Luck!

The way to do it is to iterate over the tab pages and for each one call TabControl.GetTabRect. If your mouse coordinate exists inside the returned rectange, set that tab to the selected tab.

Hi,
There is no need to use like instead of this we can use between. In addition of date we have to use timestamp also. I think this might cleare you.
Thanks

char fields will not order dates as you think - they will order them using a text search, not a date search, you must store the data in a date field of some sort.
|
|
|
|
|
You can do:
select * from table where cast(myColumn as dateTime) between '2005-12-1' and '2005-12-31'
but that's for mssql, i'm sure there must be convert function in sybase
