It seems not so complicated a project for you to design for. Now that you have three types of equipment, why not design three different forms for each type?It's no need to construct a perfect design in one project,at least not for this one ,right?To achieve your goal is OK,right?

I think you'd better create a control(label, textbox,etc..)first associated with that item you clicked, then add to it to your TableLayoutPanel's controls. Hope can help you.

You'd better make sure the destination directory exist while coping file.Hope such code can help:

string strPath = AppDomain.CurrentDomain.BaseDirectory + @"UserImages\";
// check the directory existence
if(!Directory.Exists(strPath))
Directory.CreateDirectory(strPath);
//...your file copy code here...
// eg.
// File.Copy("d:\\a.txt", strPath + "b.txt");

The SqlDataReader has no such method, please take a look at this below: SqlDataAdapter s = new SqlDataAdapter("...sql...", Conn); DataTable dt = new DataTable(); ; s.Fill(dt); DataRow dr = dt.Rows[dt.Rows.Count - 1]; Hope it's usefull for you!

Another solution: CTRL + K + F :laugh: Regards, Dealon

I think the so called process is you project itself, right? You may check your code and call the method "Close" or "Flush" of a stream that accessing that file. Maybe I need some of your oritinal code for more information. Regards, Dealon

Gareth, I think i need to get a new project to reproduce such problem because my original project has as many as 40 windows.Some work ok while others not.I don't known which code cause such errors and I will find out the codes exactly. Later, I will show you more information for the errors. Gareth,Thank you very much. Regards, Dealon.

Thanks Gareth. I want to show my one child window twice, and the first time it worked correctly, but then: dlg.Show(); at this code, it occured error "OutOfMemoryExcpetion" -Create handle failed. ps: my some other windows like it wouldn't show suck error. And this is a child window of one MDI window.I don't known why?

Hello there. When i run my MDIChild style window the second time, it occured an error: OutOfMemoryExcpetion-Create handle failed.I don't known why, because some child windows can't occured this error.

"Cannot insert duplicate key row in object with unique index .\r\n51062\r\nThe statement has been terminated."

was the key field inserted with the same value? I think the best way for you is to copy the sql statement here, because the error occured in sqlCommand.ExecuteNonQuery();

Thank you Pallini.I got it... But i found this code can't work. class aa { public: aa():x(5) { }//... }; it said x(5) is not a base class. Thanks once again! :)

Hello all. I have this code with something error occured: //------------------------------------------ #include "iostream" using namespace std; class aa { public: aa() { aa(5); } aa(int t) { x = t; } void print() { cout << x << endl; } private: int x; }; int main() { aa t; t.print();//this can't output "5", why? return 0; } ///--------------------------- As is descriped above, thanks in advance!

Thanks Guffa for your help. I think my incorrect code copied confused you. The fact is like this: 1)This code can work and the drNew.ItemArray have my wanted data. ------------ object[] obj = new object[dr.ItemArray.Length]; dr.ItemArray.CopyTo(obj, 0); drNew.ItemArray = obj; 2)But the method below seems bad. ------------ drNew.ItemArray = new object[dr.ItemArray.Length]; dr.ItemArray.CopyTo(drNew.ItemArray, 0); dtDest.Rows.Add(drNew); i found drNew.ItemArray is still empty.I don't known why?

Thanks Christian Graus for your reply. The issue is : After "CopyTo" operation, the destination array(here is drNew.ItemArray) is still empty.

It's easy! You can pass your parent form to child form, and then you can do what you want. have fun.
