Rewrite it as a Windows service if it won't need user interaction.

You can take a look at the Guadagno Task Scheduler, an article here on CodeProject. http://www.codeproject.com/useritems/Guadagno_Task_Scheduler.asp.

This application is a pluggable Task Scheduler that lets you write your own task to schedule. It comes with a RunCommand plug-in that provides the scheduling for Command Line files.

Here are some of my articles.
Hope this helps!

Have I DataBinding or DataRelation problem?

Hi everyone!

In dataset "dsbasis" I have table "ShopGood". I have another table "Good" which don't belong to dataset and contains only important data of ShoopGood for show in datagirdview. I add this table to dataset and I create relation betwen this two tables. I also have more textboxes bounded to dataset and datatable "ShopGood".

My problem is, that when I change position in datagrid, values in textboxes stay unchanged. Can anybody tell me why?
If I set datagrid datasource to the table which textboxes are bounded all works fine.

My code:
DataTable dTable = new DataTable("GoodTable");
// fill datatable for datagrid
dTable = dShopGood.ListOfGood("");
// set datasource
dgrShopGood.DataSource = dTable;
dgrShopGood.DataMember = "";
// create datarelation betwen datatable shown in datagridview and
// table ShoopGood in DSBasis
dsbasis.Tables.Add(dTable);
dsbasis.Relations.Add("rel_ShopGood_GoodTable", dTable.Columns["ID"], dsbasis.ShopGood.Columns["IDGood"]);

// set databindings
txtMark.DataBindings.Add("Text", dsbasis, "ShopGood.Mark", true);
txtName.DataBindings.Add("Text", dsbasis, "ShopGood.Name", true);
// fill dataset for bounded textboxes
dShopGood.CRAllDetail(dsbasis);

Thanks in advance,

ListView iteration problem

Hello All,

I have a listview with which I want to iterate through and set focus on each item, this I want to do in the order that they are presented to the user within the listview and independent of the index order of the item collection.

The listview I have groups data when the headers are clicked, it looks good, but the problem with this is that when the headers are clicked the indexes of the item collection are no longer in order and are scattered within the listview. This means that focus on each item jumps up and down. This is not what I want.

Thanks for your knowledge and time,

Robert

Calling method on control causing problems

Dear all,

I have a problem that I haven't encountered before. I have two forms. I would like to call a method that changes something on another form ( different class ), which happens to be a usercontrol. This my code :

Form A :

private void toolStripButton1_Click(object sender, EventArgs e)<br />
        {<br />
         UserControlMain cc = new UserControlMain();  <br />
         ultraDockManager1.PaneFromControl(cc.webBrowserPanel).Close();<br />
        }

This doesn't seem to work. The panel on from B is not close, but the application crashes instead.
If I add a method on Form B , and I invoke the following method directly, it works :

public void CloseWebBrowser()<br />
{<br />
    this.ultraDockManager1.PaneFromControl(this.webBrowserPanel).Close();<br />
}

If I try to invoke the method on Form B from Form A by :

private void toolStripButton1_Click(object sender, EventArgs e)<br />
        {<br />
         UserControlMain cc = new UserControlMain();  <br />
         cc.CloseWebBrowser();<br />
        }

The application crashes as well.

Can anyone tell me what I'm doing wrong ? Is the behaviour of a UserControl different than to a normal winform.

kind regards,

Hi,

Rick van Woudenberg wrote:

this creates a new UserControlMain, not a reference to the one you probably already had.
I guess it is not sufficiently initialized to support the attempted operation,

I suggest you try to catch the exception that occurs, so you get useful details on it.
YAs a last resource yu may want to enclose your Application.Run() in a try-catch
that dumps the entire Exception.ToString() to a MessageBox.

I suspected something like that. I will try to catch the exceptions like you told me. Maybe that will shed a little light on the solution. In teh mean time, is it possible to somehow call the Method below on Form B from Form A ? :

public void HidePanelWeb(object sender, EventArgs e)<br />
        {<br />
            this.ultraDockManager1.PaneFromControl(this.webBrowserPanel).Close();<br />
        }

kind regards,

Hi Rick,

I dont know enough about your app, but I am guessing you may be trapped by an
IllegalCrossThreadCall. Are you by any chance calling this from a thread that is not
the main thread ? If so, read up on Control.InvokeRequired and Invoke().

Luc,

Thank you for your help though. You basically fixed the problem for me. Your comment : 'maybe it's not referenced properly' got me thinking. Turned out that the object was already referenced in the application. I invoked tthe method and it work perfectly. Once again, thank you for putting me on the right track !!

Cheers

Hi!
I am using C# 2005, the size of '.exe' file of project in Release folder is increasing day by day as I add functionalities in project and now it is reaching around 2MB...

Can any one tell me whats the reason of this and how to control it? Because normally I dont see such big exe files...

Thanks in advance...

Wow! That's quite big. How many lines of code are compiled to make your exe file?

Code? Bah. Just a few bitmaps as embedded resources would do that easily.

Thanks for reply...

There are approximately 10000 or so lines of code and also 10-15 images/icons...

Is it because of code or images? and whats its solution?

You could use a seperate resource assembly to contain your images, etc. That would remove them from the exe and give the benefit of allowing them to be updated independent of it. However, I don't see a problem with a 2MB exe. I've seen much larger ones, from code alone.

If this exe wont cause any problem then its good, however I will appreciate if you guide me how to create a separate resource assembly to contain images..

Take Care, Cheers...
