Dear sir,
i have a require ment to cut the corners of the form .
i have a windows form with a shape square.& i have a background image for that
i want to cut the corners of the form along with the back ground image.
for that i have one algorithm , I have written it in the form_paint event .
but it is not cut the corners.
i paste the code here.

Dear sir ,
this is balaji working as software engineer in innobox, in india. i have problem regarding the paint event.
step1: i have a login screen when i click on login it show a recorder form to record our video.
this is th code i have written in the login button
----------------------------------------------------------------------
private void btnLogin_Click(object sender, EventArgs e)
{
this.Cursor = Cursors.WaitCursor;
tbLogin.Enabled = false;
tbPassword.Enabled = false;
btnLogin.Enabled = false;
btnCancel.Enabled = false;
CurrentUser.rf = rcf;
//if (Communicator.GetUserInfo(tbLogin.Text, tbPassword.Text, rebrandLoginForm.label1)) {
System.Windows.Forms.Label lblName = new Label();
lblName.Text = "idle";
if (Communicator.GetUserInfo(tbLogin.Text, tbPassword.Text, lblName))
{
//Rebrand_Control.UsersInformation.CustomerID = CurrentUser.CustomerID;
//Rebrand_Control.UsersInformation.UserID = CurrentUser.UserID;
//Rebrand_Control.UsersInformation.Username = CurrentUser.Username;
//Rebrand_Control.UsersInformation.Password = CurrentUser.Password;
//Rebrand_Control.UsersInformation.ResellerID = CurrentUser.ResellerID;
//Rebrand_Control.UsersInformation.AccessLevel = CurrentUser.AccessLevel;
//Rebrand_Control.UsersInformation.PLS = CurrentUser.PLS;
//Rebrand_Control.UsersInformation.PlaybackURL = CurrentUser.PlaybackURL;
//Rebrand_Control.UsersInformation.ResellerAdmin = CurrentUser.ResellerAdmin;
//Rebrand_Control.UsersInformation.isPremium = CurrentUser.IsPremium;
//rebrandLoginForm.GetRebrandImages(tbLogin.Text, tbPassword.Text);
//rebrandLoginForm.label1.Text = "Status: Loading Graphics...";
//while (!rebrandLoginForm.gotRebrandedImages)
//{
// Application.DoEvents();
//}
rcf.Show();
this.Hide();
}
else
{
MessageBoxForm mbf = new MessageBoxForm("Username or Password incorrect. Please try again.");
mbf.ShowDialog(this);
tbLogin.Enabled = true;
tbPassword.Enabled = true;
btnLogin.Enabled = true;
btnCancel.Enabled = true;
// focus on login box
tbLogin.SelectAll();
this.ActiveControl = tbLogin;
}
this.Cursor = Cursors.Default;
}
step:2 afetr login the recordform_load evevnt will fire
this is the code
--------------------------------------------------------
this.Location = new Point(this.Location.X, SystemInformation.WorkingArea.Top);
//this.Text = Rebrand_Control.UsersInformation.ProperTitle + " - Record Video";
//this.Icon = Rebrand_Control.UsersInformation.ProperIcon;
lblName.Text = CurrentUser.FirstName + " " + CurrentUser.LastName;
lblVersion.Text = "Version 6.8";
lblTimeAvailableTimer.Text = CurrentUser.TimeLeft;
if (CurrentUser.SecondsLeft == 0)
{
MessageBoxForm mbf = new MessageBoxForm("You have reached your recording time limit. Remove old videos to free up more time.");
mbf.ShowDialog(this);
this.pbStartRecording.Enabled = false;
}
else if (CurrentUser.SecondsLeft < 60)
{
MessageBoxForm mbf = new MessageBoxForm("You have less than one minute of recording time left. Remove old videos to free up more time.");
mbf.ShowDialog(this);
}
// delete old videos
string[] files = System.IO.Directory.GetFiles(Application.StartupPath, "*.wmv");
foreach (string file in files)
{
System.IO.File.Delete(file);
}
string[] tfiles = System.IO.Directory.GetFiles(Application.StartupPath, "*.jpg");
foreach (string file in tfiles)
{
System.IO.File.Delete(file);
}
string[] tfiles2 = System.IO.Directory.GetFiles(Application.StartupPath, "*.gif");
foreach (string file in tfiles2)
{
System.IO.File.Delete(file);
}
string[] tfiles3 = System.IO.Directory.GetFiles(Application.StartupPath, "*.bmp");
foreach (string file in tfiles3)
{
System.IO.File.Delete(file);
}
string[] tfiles4 = System.IO.Directory.GetFiles(Application.StartupPath, "*.avi");
foreach (string file in tfiles4)
{
System.IO.File.Delete(file);
}
string[] tfiles5 = System.IO.Directory.GetFiles(Application.StartupPath, "*.mod");
foreach (string file in tfiles5)
{
System.IO.File.Delete(file);
}
string[] tfiles6 = System.IO.Directory.GetFiles(Application.StartupPath, "*.mpg");
foreach (string file in tfiles6)
{
System.IO.File.Delete(file);
}
pbStartRecording.Enabled = true;
LoadScripts();
step 3: after this the paint event i.e private void RecordForm_Paint(object sender, System.Windows.Forms.PaintEventArgs e) it will fire
it is executed. i put a break point at this event then i press f10 after execution of this event the program counter again comes to the paint event. it loops in this event infinitly.
even if i press f5 then also it is in the same event.
if i remove the break point then execute it will show the output but the code what i written in the paint doesnt cut the corners of the screen.
the code i have written in the paint event to cut the corners of the windowform as well as img which is on the top of the form.
the code is
--------------------------------------------------------
Graphics g = e.Graphics;
// Rectangle mainRect = new Rectangle(0, 0, 578, 470);
Rectangle mainRect = new Rectangle(0, 0, 650, 500);

Paint events are tricky to debug because the debugger keeps popping up and sending the application window to the background, so it needs repainting again when it regains the focus. One way around this problem is to use remote debugging - run the application on one computer and the debugger on the other.

Hi,
i have a problem and i hopr you can help me,
i want to create a user control with textbox and listbox. the listbox is binded to a collection and it works as autocomplete of the text box. i did some search and i found some solution but i still have the problem which is i want the list to be appeare outside of the usercontrol and be almost as popup list because if i make the usercontrol hieght to be the hieght of the list then the space with other controls in the form will be large.most of solutions suggest to use form as popup of the control and put the list on the popupform, its not work because the focus will be lost from the main form when user navigate through the list and have alot of problems when to show/Hide the popup control.
what i want is almost to make a control just like the combobox with its items dropDown list.
please i need help its too urgent

Hello,
I am trying to retrieve the Index property of a row in the SelectedRows collection (Managed C++, .Net 2.0).
lRowIndex = pSelectedRows[idxSelectedRow]->Index;
I get -1 value, and I suspect this is because of shared rows.
Still, I need to know the row index. How can I find it ?
On the other hand, the same code works well if the SelectedRows is passed as data in a DoDragDrop operation (maybe then, shared rows are not used).
Thank you,
Cristian
|
|
|
|
|
The approach I was trying was the correct one: to retrieve row index you may use
lRowIndex = pSelectedRows[idxSelectedRow]->Index;
I was failing to get correct values not because of the shared rows, but because of the fact that I was altering the "selected row" data in a previous set of CurrentCell DataGridView member. Now I corrected it and everything works fine, so this topic may be closed. Thank you.

Hi Guys,
I have a .net application, in which a frequently used screen experience a GDI leak. Using GDILeakDetector, i found the kernel address of the bitmap object, which is causing the leak.
Handle : 0x3a0509ea
ObjectType : Bitmap
Kernel Address : 0xe2cc9d28
Extended Information : Width: 12, Height: 12 , Bits/Pixel: 32
Now i need to find out what is that object in the screen (i.e) object details, from the kernel address. Can u pls help me out in this how could i point out the object in the screen and also how to dispose it on form close.
Thanks in advance

Search for every use of the Bitmap class and ensure that the object is always disposed when you've finished using it. If, for example, you allocate a bitmap in a method and you assign it to a local variable (not a member variable of the class), use a using block to ensure it's disposed of automatically.
If you assign it to a member variable of a class, for example a Form, then you should override the Dispose(bool) method and when the parameter is true (to indicate disposing rather than finalizing), call Dispose on the bitmap. The Framework will call the Form's Dispose method when the form is closed. Visual Studio automatically generates an override of Dispose which you will find in the Designer file (e.g. MyForm.Designer.cs) in VS2005 and later.
(It is not safe to call Dispose on member variables when Dispose(bool) is being called by the finalizer, because the order in which finalizers are called is essentially random. The Bitmap may already have been cleaned up by its own finalizer.)

Hi,
I'm currently learning C# and WinForms and practicing on Visual C# 2008 Express Edition.
I wanted help regarding the look and feel of menuStrip and toolStrip controls - they have a blue Office 2003'ish look and feel; I want them to look native on XP (or Vista). How can I do that? Thanks..
|
|
|
|
|
Other than the fact that .NET 2.0+ has many different styles for menu items (the RenderMode property of menustrips can be set to System and that will allow the appearance to change with the OS visual style). If you want to customize the menustrips beyond that aspect, you may consider looking at one of my articles on custom toolstrip renderers: Custom ToolStrip Renderers[^]

Do you have the visual styles enabled in your entry point? E.g:
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new Form1());
}

Yes, I checked that part. It was enabled. Sorry I didn't reply; I had to change the RenderMode as suggested by Thomas..

I have a similar problem. This question was asked in 2008 and no one ever replied. Searching web does not find an answer either.
Working backward I found that when you use a parameter "this.Text" or anything with "this" you cannot add it from the Toolbox. The control works as expected with each instance of the tool working from its own parameters. You can copy and paste it with out problem with out problem. You just cannot get it from the Toolbox.
So many years of programming I have forgotten more languages than I know.
