I have a method which places a control in the specified Form/Control. But I can't figure out the optimal signature.
void GetCustomControl(object FormOrControl, int Top, int Left)<br />
{<br />
<br />
<br />
<br />
}
I've specified FormOrControl as an object, but I would prefer if the caller handed me his Controls collection, so I can just add my control without having to look up the TypeOf object being handed to me.
How do I write the signature for that, and how do I do I reference it in the method?
I tried specifying CollectionBase, but that wasn't right.

Then why not pass a ControlsCollection then?

Won't work. When the caller passes in the Controls collection of a Control, this error is thrown:
Error 3 Argument '1': cannot convert from 'System.Windows.Forms.Control.ControlCollection' to 'System.Windows.Forms.Form.ControlCollection'
Looks like I'll just have to accept an Object FormOrControl, and check TypeOf before using Control.Add to add my control.

Just to clarify - my method wants to be able to place my custom control into a Form or Control's Controls Collection.
ControlCollection is specifically the ControlCollection of a form.
Here's the code I ended up using:
<br />
void GetCustomControl(object FormOrControl)<br />
{<br />
<br />
if (typeof(Form) == FormOrControl.GetType())<br />
{<br />
((Form)FormOrControl).Controls.Add(RBO_Panel);<br />
}<br />
else
{<br />
((Control)FormOrControl).Controls.Add(RBO_Panel);<br />
}<br />
}<br />

If you just want to uses the "collection" to add your control, you can do this: void GetCustomControl(ControlCollection controls, int top, int left). Thus, you can use it thus: GetCustomControl(Form1.Controls, 0, 0); or
GetCustomControl(Button1.Controls, 0, 0);<br />
<br />
Also, <code>void GetCustomControl(Control control, int top, int left); should also work. Thus, you can do this: GetCustomControl(ListView1, 0, 0);. This should work since all controls inherit from "Control".

See my comments above. I need to accept either a Form or Control. So I can't use ControlCollection or Control.
I was being lazy, I'll just take the Object and cast it as necessary.

A Form is a Control. Also, I was wrong in my above post. The ControlCollection should be as follows: void Func(System.Windows.Forms.Control.ControlCollection coll, ...)

You are right. I hadn't considered that a Form was a Control. I'll just use Control TargetControl in my signature, and simply do
TargetControl.Controls.Add(myCustomControl)<br />
Thanks, everybody.

Hello there!
I have three problems  while working on the application in Visual Studio 2005 in c#. 1st. i want to ask that i want to display the system date and time on my form but in the format like [month] [day] [year] and [time] but sepratly not like month/day/year as i want to save them sepratly in the database table fields not in the same field can any one help me how i can do it? 2nd. i want to set any form as start up form how can i do it? 3rd. i want to introduce the crystal report in my application please tell me wht the steps are there to follow ?

1) Use a Label? Then label.Text=System.DateTime.Now.ToString ( "MM dd yyyy HH:mm" ) or some other format, look 'em up.
2) Add the exe to the user's Startup?
3) Invite your app and Crystal to a party, introduce them there.
|
|
|
|
|
3. Not recommended. I invited Crystal to a party once and I still haven't found my cat!
Take care,
Tom

Seems wasteful.
I'm not even sure what you mean in 2 -- do you mean you want the app to startup when a user logs in?
|
|
|
|
|
its not waste full becuase i want the date format in sperate labels becuase while working with the Inventory application sale portion i have a requirement to view the record of all sale in the spcified month so thats y month in seprate coloumn of SQL is must.
And in 2nd point i want to put the winForm in start up becuase after creating each form i want to see its out look by running it.

How it looks on screen has very little to do with how it's setup in the database.
Oh, so that's what you mean. In the Solution Explorer, right-click a project, and select "Set as StartUp Project". But the project has to be an exe, not dll. And the form has to be the main form of that exe.

thank u very much i have sorted out the problem for start up can u please tell me that wht will i have to do put the date month and year seprate fields in the database ?

No I will not, it's a bad idea.

Is anybody aware of a bug (and a fix) in VS 2005 SP1 that generates errors in datasets when adding an insert/update/delete query. The error is "reference is not set to an instance of an object" (usually line 1) and is generated because the "Name" attribute is not saved in the xml file.
Sometimes, simply loading the dataset in Visual Studio, and saving it clears all the "Name" attributes in the xml; and this has happened on multiple computers.

hi there,
i m making an app that need to decompress Zlip file from File data in byte[] in a specified format
i.e.
char {4} - Header (l33t)
uint32 {4} - Decompressed File Size
byte {X} - ZLib Compressed File Data
// WHEN DECOMPRESSED
char {2} - Header (BG)
uint32 {4} - Archive Size [+8]
byte {X} - Unknown
to read this file, i created a binary reader and read what i can but i m unable to decompress it
the codes to read :
BinaryReader br = new BinaryReader(File.Open(@"C:\Documents and Settings\xmen\Desktop\g.age3scn", FileMode.Open));
string header = new string(br.ReadChars(4));
int filesize = br.ReadInt32();
byte[] filedata = br.ReadBytes(filesize);
can someone tell me how can i decompress it?

Have you tried Google[^] to look for a .NET wrapper around the zlib libraries?
|

|
|
What is this Google you speak of?

It's this new-fangled contraption that automagically gives you the answer to any question you ask. I know, it's heresey, isn't it?

And it really works[^]...
