The best way for people to communicate with your app is through WP_COPYDATA messages, it's simple and it's easy to impliment.

this[^] was the third hit on a google search of C# WM_COPYDATA, and would also have come up if you searched this site.

There's a class named ProcessControl. With it you can pause/continue and start/stop the process

You do know that people here are volunteers don't you? You should also know that most of us have real paying jobs that come first. You have to have some patience in these things.
Also, please don't use txtspk in forums.

It's still visible, no need to repost. Remember that people in the US are asleep, and the service is free, so you need to just wait until someone answers you.

Hi, Im trying to change the look/style of my datagridview control. Is there a way to change the color, border etc for specific cells. Id like every cell that doesnt contain any data to have the same color as my form without any border and cells containing data to have a white background and sunken into the form so that they appear as normal textboxes?
|

Hi,
Maybe the answer for your problem is no.
Datagridview doesn't still support for formatting any discrete cells.
DefaultGridCellStyle property is designed to format a column or all columns of datagridview.
It seem to be a solution or an answer.

|
|
|
|
So im not able to change the border for a single cell but for a specific column? how do you do that? /thanks
|
|
|
|
|
Certainly you can change the color of each cell in row databound event !!! you can access these information and set the proper color

Hi,
I have an DataGridView with total of 14 columns. Two of those columns are Images.
The application is supposed to run 24/7. The grid is constantly refreshed from background worker with new data.
New rows are added programatically into datatable which is datasource of binding source that is grid data source. Also, periodically (approx. every 30 min.) whole table is refreshed with query from SQL server.
After approximately more than 12 hrs of non stop working the grid slows down as I have more than 100.000 records displayed.
I have found that when its slows down, I just hide the image columns, the grid starts to act normaly, but then when I return those columns visible status to true, everything slows down again.
I have tried everything. Bounded images from datasource, images from cell formating event, virtual mode, really everything.
Any ideas?
Thanks in advance.

Hi,
DataGridView is a ... . I have suffered something similar. I tried to load a 33000 rows datatable and it were to slow loading.
My solution (and maybe yours) is create a new user control (datagridview with buttons to scroll up/down one by one and by one page) that envolves the datagrid but I have implemented my own datasource. When I set a dataset as a datasource, the control segments the datatable to load only the rows that I can see (10-15). Then, when I scroll down it loads the next group of rows.
It works good and is not very difficult. And the load and the scroll time have been reduced. Good luck!

Thanks for your answer,
I've allready tought about such solution and I like it. But the problem is not in the number of records. The problem is with image columns.
Yesterday I have tried my last desperate atempt to solve the problem and it works.
Here is what I have done:
When datatable refresh background worker executes (approx. every 4 seconds), then I execute the following code also (but not allways, let say every 60 min.):
int index = this.dispatchstatusImageAllCol.Index;
int displayindex = this.dispatchstatusImageAllCol.DisplayIndex;
bool visible = this.dispatchstatusImageAllCol.Visible;
int width = this.dispatchstatusImageAllCol.Width;
string name = this.dispatchstatusImageAllCol.Name;
string hdr = this.dispatchstatusImageAllCol.HeaderText;
this.gridAll.Columns.Remove(this.dispatchstatusImageAllCol);
this.dispatchstatusImageAllCol = new DataGridViewImageColumn(); // 1. most important line
this.dispatchstatusImageAllCol.DisplayIndex = displayindex;
this.dispatchstatusImageAllCol.Visible = visible;
this.dispatchstatusImageAllCol.Width = width;
this.dispatchstatusImageAllCol.ContextMenuStrip = this.gridAllMenuStrip;
this.dispatchstatusImageAllCol.HeaderText = "";
this.dispatchstatusImageAllCol.Name = name;
this.dispatchstatusImageAllCol.ReadOnly = true;
this.dispatchstatusImageAllCol.Resizable = DataGridViewTriState.True;
this.dispatchstatusImageAllCol.HeaderText = hdr;
this.gridAll.Columns.Insert(index, this.dispatchstatusImageAllCol); // 2. important line
This is probably the proof that there is a memory management problem with DataGridViewImageColumn.

Can u provide me with an example of a date routine that will return the begin and ending period for a week number. For example, if week 14 for 2007 was provided, the routine would return starting date 08/04/2007 and ending week 14/04/2007.
Input Provided - week number (1 - 53), and Year(cccc)
Output - week begin date and week end date

private void getDateRange(int weekNumber, int year, out DateTime dt1, out DateTime dt2)
{
DateTime dt = new DateTime(year, 1, 1);
//get inside week number 'weekNumber'
dt = dt.AddDays(7 * (weekNumber - 1));
//get first day of the week
dt = dt.AddDays(-(int)dt.DayOfWeek);
dt1 = dt;
//get last day of the week
dt2 = dt.AddDays(6);
}
//call it like this
DateTime dt1;
DateTime dt2;
getDateRange(26, 2007, out dt1, out dt2);

Hello,
1) I didn't responded to your question, I voted "1" for it!
2) Please don't spam my mail account, if you have something interesting to tell, everybody should benefit.
3) Again, I will not do your homework, at least not if you pay for it!
All the best,
