• Klaus Even Enevoldsen DK Making a listview thread-safe

  All I have a listview that is populated by a number of threads running in the background. I currently have to use a mutex to make the listview threadsafe. Ie, before each thread tries to update the listview it waits on the listviewupdate mutex, updates it then releases the mutex. Although this works, I'd prefer to make it a little less "bodged" and would like to make the listview properly thread-safe without having to use a mutex. When I comment out the mutex commands the listview goes crazy with spaces end weird entries everywhere, making me pretty sure that it is definitely not thread safe. In the documentation it says... Any public static ( Shared in Visual Basic) members of this type are thread safe. Any instance member ...Show All

• Wicket Modal Dialog Box focus problems and Painting Problems

  I have written a Windows Forms application using C++ (.NET 2.0). I have encountered two problems I believe are related. The first occurs sometimes when I open a modal "dialog box", in the form of a MessageBox.Show, FileDialog or custom form using ShowDialog. The dialog box does not appear on top of my application, it is hidden and thus gives the illusion that my application has frozen (The Z-Order is not first). The second is that after displaying these dialog boxes (When they do show up on top), the controls under them do not repaint themselves, leaving "ghost" images of the dialog box that was just closed. I have found several threads on this forums posted by others who have encountered the same, or similar, problems, ...Show All

• Personal Information Withheld User control with Events

  I have to develop an user control that should generate specific events (with data). Does somebody know where to find an example or guideline for this Thanks in advance.

• ChiuHwa Problems with "Show Dialog" and Large amounts of data

  I have an inventory lookup form, called from many different user controls, that could easily be loaded with large amounts of data (150000+rows). My problem is that with only 22000 test records it takes about 35 seconds to load. This would be acceptable if I could load it up the first time and then simply hide it. The problem is that the ".showdialog " method of the form, while it works and allows me to pass the selected ID to the calling form, brings up a new instance every time causing the delay reloading every time. In VB6 you could hide the form then show it again and pass a global variable containing the selected ID from one form to another. In VB.net 2005 the Only way to pass the variable from the one form to the other, ...Show All

• Mark Beiley datatable

  i have written the following code: dataGridView.DataSource = dataTable; but when I update the dataGridView manually, dataTable events do not raise why (I have defined the events correctly.) Which events are you having a problem with and could you post the relevant code what datatable events There are no events to be kicked off since you are not really dealing with the datatable in the sense that you are doing something with it, you are just telling the dataGridView to set its datasource to the datatable, which the events in this case would be fired in the datagridview, such as ColumnAdded etc... ...Show All

• Ntc newbie: binded data for date and change the datetime format

DateTime date = Convert.ToDateTime(dataset.Tables["master_table"].Rows[CurrentRowIndex].ItemArray[15].ToString); xrBill_Date.Text = date.Day + "/" + date.Month + "/" + date.Year; The output is what i wanted ---> eg. 18/1/2007 but the prob is the date is repeated (eg. there are 5 bills...the date from the 1st bill is repeated from 1st bill to last bill) So..i do this... xrBill_Date.DataBindings.Add(new XRBinding("Text", dataset.Tables["master_table"], ColumnName_Master[15])); DateTime date = Convert.ToDateTime(xrBill_Date.ToString( ...Show All

• HotKeeper drag and drop in FlowLayoutPanel

  can i perform a drag and drop operation in a FlowLayoutPanel Yes, it implements the normal D+D events. Actually, this isn't correct. Inside FlowLayoutPanel.Controls is a little used function called SetChildIndex(Control c, int index) which allows you to set an object to a specific index. Since FlowLayoutPanel uses control's indices to determine which order to draw them in, you can set this to whichever control's index you are wanting to swap with, and it will bump that controls index up by one, and every one after that. Changing the Location property won't work, it is being controlled by the FlowLayoutPanel. That is its job. You'll need to rearrange the order of the controls in the ...Show All
