This piece of code should do for you :
private void startButton_MouseHover(object sender, System.EventArgs e)<br />
{<br />
startButton.BackColor = Color.Yellow;<br />
ToolTip toolTip = new ToolTip();<br />
toolTip.ShowAlways = true;<br />
toolTip.SetToolTip(startButton, "Whatever Message...");<br />
<br />
}

Thanks a lot is working. I 've also tried to put
ToolTip toolTip = new ToolTip();
toolTip.ShowAlways = true;
toolTip.SetToolTip(startButton, "Whatever Message...");
in the Form_load event and is work too.
Thanks, bye.

Set tooltip property at design time , if the button is created dynamically then user code to set tooltip property

Hi,
I have a windows forms app that contains a datagridview, with two filtered columns, some textbox columns, and a checkbox column. The filtering on the dgv is accomplished by using dropdowns on the column headers of the two filterable headers and this happens reasonably quickly.
My problem comes when I try to set the value of all the checkboxes to either checked or not checked. If I have a small number of rows in the dgv then each check operation takes about .0015 of a second. If I have a large number of rows that time jumps to 1.5 seconds per row. When I use the filters the dgv updates in about 2 seconds. I am at a loss.
The code I use to update the dgv checkbox column is:
<br />
If btnSelectRecords.Text = FormConstants.ControlConstants.DESELECT_ALL_RECORDS Then<br />
For Each row As DataGridViewRow In dgvLoanRecords.Rows<br />
row.Cells(FormConstants.GridViewConstants.SELECTED).Value = False<br />
Next<br />
btnSelectRecords.Text = FormConstants.ControlConstants.SELECT_ALL_RECORDS<br />
Else<br />
For Each row As DataGridViewRow In dgvLoanRecords.Rows<br />
row.Cells(FormConstants.GridViewConstants.SELECTED).Value = True<br />
Next<br />
btnSelectRecords.Text = FormConstants.ControlConstants.DESELECT_ALL_RECORDS<br />
End If<br />
Can someone point me in the right direction to speed this process up.
Thanks
Jim

I currently have a single threaded application that contains a
strongly typed dataset (called dsdataset1) with 3 tables, all bound to
comboboxes on my main form.
This works in its current form (the datasets are filled on the form
load event).
I noticed a problem whereas the form doesn't draw until the datasets
are filled, so I figured I'd use the background worker component to do
the dataset filling on a seperate thread.
For some reason, I cannot get this to work properly. My program
loads, and my dataset is filled, however my comboboxes are no longer
bound to the dataset. It's driving me nuts.
I've tried passing the dataset back out during the runworkercompleted
event (i.e. dsdataset1 = ctype(e.result, dataset)), but even that
doesn't work. I even tried resetting the bindingsource.datasource for
my combobox back to the dataset after passing the dataset out, but no
go. I'm at a loss.
Any suggestions?

Hi to everyone.In my visual c++ window form appplication, i want to open a directory (of images) and see the images in a picturebox.
I know that i can use folderborwserdialog to select the directory but when i've the path selected in the folderbrowserdialog how can i use the files in it? Have i to pass something to an imagelist??
Thanks for answers, bye .

Where do you want to show those images? If you have another form for images then you can retrieve all the images from the folder path you got using folderbrowsedialog
|
|
|
|
|
I've a solution...(take the directory name and gets the files in it).
String^ folderName;
array <string^>^ files;
System::Windows::Forms::DialogResult result = folderBrowserDialog1->ShowDialog();
if ( result == ::DialogResult::OK )
{
folderName = folderBrowserDialog1->SelectedPath;
}
files=System::IO::Directory::GetFiles(folderName);
if(files->Length!=0)
for(int i=0;i<files->Length;i++)
{
FileInfo^ fi = gcnew FileInfo(files[i]);
if(fi->Extension==".jpeg" || fi->Extension==".bmp"||fi->Extension==".jpg")
{
Bitmap^ cap=gcnew Bitmap(fi->FullName);
this->capture_img_box->Image=cap;
System::Threading::Thread::Sleep(1000);
this->Refresh();
Application::DoEvents();
}
}
Thanks however for the answers.
Bye.

no, i only want change specific row back color, and i want know how to do that ?
thanks
|
|
|
|

I don't think you can do that in Windows Forms.
|
|
|
|
|
i think can be done, but i don't know how?
like properties BackColor of DataGrid, it change bg color of odd number row
|
|
|
|
|
I was just wondering because datagrid does not have a Row(s) property.
|
|
|
|
|
Sorry a bit of a late reply but hopefully this will still help you.
You can set a rows color using the following line:
dataGridView1.Rows[i].DefaultCellStyle.BackColor = Color.Blue;
(where 'i' is the current row as i am assuming you will have a loop so you can set the color depending on the row index).
You can also set the default row and cell styles using the properties window however this will apply to every cell and row.

Hello All,
Please help me solve this problem. I want to create an editor/designer that will handle the following situation.
I have an abstract class Marker, and many different implementations that will not be exposed to the user.
The markers are created through a factory system, MarkerFactory, and I have a collection
of the markers in a Control that I will to create the editor/designer for.
<br />
public class Marker<br />
{<br />
protected Marker(...){}<br />
} <br />
<br />
internal class AMarker : Marker<br />
{<br />
} <br />
<br />
internal class BMarker : Marker<br />
{<br />
} <br />
<br />
public class MarkerFactory<br />
{<br />
public Marker Create(...) {return newMarker;}<br />
}<br />
<br />
public class MarkerControl : Control<br />
{<br />
[MarkerDesigner]<br />
[DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]<br />
public IList<Marker> Markers<br />
{<br />
get{ return markerList;}<br />
}<br />
} <br />
Any guide/hint as to how I could create such an UITypeEditor, that will work with the
factory system.
Best regards,
Paul.

I cannot believe that in this day and age I cannot find a control to edit time.
There are controls which can almost make coffee, but not one where a user can easily enter the time.
I am not talking about the 13:45:65 PM thing where the user must select each two digit pair,
edit it or run the minute spinner buttons. It must be easier.
Like a clock view where you drag the hour, minute and seconds hands, and it snaps to every 1,5,10,15,30,60 or whatever minutes
and you can select Now with one click, and so on.. Surely nothing compared to making coffee.
Am I looking in the wrong places ?
Please help.
