• Windows Forms DataGridView Control replacing certain values with a string

  I have a datagridview control which uses an array of class objects as its data source. Is it someway possible to set it up so that certain values in the data are shown differenty in the control. What I actually want to do is when the value is -1 show either nothing or a dash. Cheers, Gareth Hi Gareth, you could use the CellFormatting event for formatting your original data, something in a way of: private void dataGridView1_CellFormatting( object sender, DataGridViewCellFormattingEventArgs e) { // You can adjust the column/type/value checking here, according to your needs if (e.ColumnIndex == 1 && e.Value != null && e.Value.ToString() == "-1&q ...Show All

• Smart Device Development PhoneCall with CF?

  Hello, is it possible to establis a PhoneCall by using the Compact Framework I donst find anything about it and search the hole day. Only by using unmanaged code I think (I can’t code c++) or by using OpenNetCF which I don’t want to use. Can anyone Help Thank you so much twickl NETCF itself does not include support for that, but it is possible via TAPI. As you already know there's TAPI wrapper from OpenNetcf.org. If you don't want to use it then you'd need to create your own TAPI wrapper. It does not involve any actual C++ but very good C/C++ understanding and TAPI familiarity is required. Or, if you're developing for Windows Mobile 5.0 and don't need support for older platforms, you can use Micr ...Show All

• Windows Forms DataGridView.Sort explodes after modifying/adding row(s)...

  I am creating a little app that has a DataGridView to keep track of tasks. In the DataGridView I have several columns - an id (a textbox column set with the ValueType of Type.GetType("System.Int32")), a priority, an image column (representing the priority with an image), and a few other text, date, and checkbox columns. When I first load my application, I read in the data from a DataTable in a DataSet, and create a new row in the DataGridView for each row in the DataSet. This allows me to select the right image for the image column based on the value of the Priority column. When the application shuts down, it does something similar - for each DataGridViewRow in the DataGridView, it extracts the data that needs to be written to the disk, ...Show All

• SQL Server Distributed Transactions between servers on different VLANs

  Hi there, I have two SQL servers, SERVERA and SERVERB. They are on two different VLAN's within our corporate network. They are physically only about 5 feet apart. SERVERA is SQL2005 while SERVERB is SQL2000. I am running a distruted transaction as a result of an insert on SERVERA which then causes a Stored procedure stored on SERVERA to insert a record on a table on SERVERB. I know my syntax is correct, 'cause I can get the Process to work between two servers (one SQL2000 and the other SQL2005) on the same VLAN. But when I run it in the problem environment, I get the following error message: SQL Execution Error Executed SQL Statement: INSERT INTO Tablea(recordid, recordtext) values(3, 'Testagain') Error source: .Net SQLClient D ...Show All

• .NET Development Best method to insert the content of an XmlWriter into another XmlDocument?

  I have an XmlWriter stored as a MemoryStream. I would like to insert it into an existing XmlDocument. So far I have loaded the XmlWriter into its own XmlDocument and then imported the nodes into the existing XmlDocument. Is there a better way using XmlDocument of doing this Thanks, Tad p.s. I have used the CreateDocumentType (see below) in my code but it appears incredibly slow. Is there a faster method of creating the Document Type element When I tried it on my XmlWriter it raised an error. xmldoc.AppendChild(xmldoc.CreateDocumentType("svg","-//W3C//DTD SVG 1.1//EN","http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd",null)); Thanks Sergey.

• Windows Forms ArgumentException from BindingSource when closing a form

  I have an issue where closing a form containing a binding source results in an unhandled exception as follows: Unhandled Exception: Cannot bind to the property or column StartDate on the DataSource. Parameter name: dataMember System.ArgumentException Stack Trace: at System.Windows.Forms.BindToObject.CheckBinding() etc... Any idea what the cause of this is It's thrown once the OnClosing has completed and the form is being disposed, but only happens on a couple of forms whereas most are fine. All of the forms inherit from the same base class, so I'd assume the issue relates to the form, or the data object bound to the BindingSource, but there's nothing different in the ones that throw this exception as far as I ...Show All

• .NET Development Returninig a string from the Main method in a Console Application

  Can I return a string value from the Main() method of a Console Application The scenario I am looking for is: 1. Program1 returns a string (say "hello") 2. Program2 must take this as input and process the job as required (say print "hello" twice). Is it possible for me to return a string instead of an integer or nothing using Main() method No it's not. What you can do is write the standard output stream from Program1 (e.g. using Console.WriteLine) and read from the standard input stream into Program2 (e.g. using Console.ReadLine). Then you can pipe text from Program1 to Program2 on the command line. e.g.: C:\> Program1.exe | Program2.exe ...Show All
