Re: DataSet not Updating Database

2-Jun-04 10:44

It should be obvious: you need to assign a command (like a SqlCommand, OleDbCommand, or whatever is appropriate) to the DataAdapter.UpdateCommand property, using whichever DataAdapter is appropriate. How do you expect the DataAdapter to update the database if it doesn't know how to update the database?

If you use a simple SELECT statement, then you can also use a command builder like the SqlCommandBuilder to build the INSERT, UPDATE, and DELETE statements for a DataAdapter. See the .NET Framework SDK documentation for more details.

Thanks I will look at that.

Huh?

Want to mouse click a toolbar button?

How can I programmatically push a toolbar button?

foreach (ToolBarButton refBtn in toolBar1.Buttons)
{

if refBtn meets some condition then click it. Just like a mouse click.
refBtn = left moust click;

}

thanks

If the ToolBar.ButtonClick event handler is accessible (i.e., in the same class or with an access modifier that allows it to be access from outside your class), then just call it like so:

public class MyForm : Form
{
  private ToolBar tb;
  public MyForm()
  {
    tb = new ToolBar();
    Controls.Add(tb);
    tb.ButtonClick += new ToolBarButtonClickEventHandler(tb_ButtonClick);
    // Add buttons
  }
  private void tb_ButtonClick(object sender, ToolBarButtonClickEventArgs e)
  {
    // Do something depending on the button.
  }
  public void ClickButton(ToolBarButton b)
  {
    tb_ButtonClick(tb, new ToolBarButtonClickEventArgs(b));
  }
}

Otherwise, you'll have to P/Invoke the SendMessage API and send the TB_PRESSBUTTON message like so:

[DllImport("user32.dll")]
private static extern IntPtr SendMessage(
  IntPtr hWnd,
  uint msg,
  IntPtr buttonID,
  IntPtr press);
public void ClickButton(ToolBar tb, int position)
{
  if (tb != null)
  {
    SendMessage(tb.Handle, 0x0403, new IntPtr(position), new IntPtr(1));
    SendMessage(tb.Handle, 0x0403, new IntPtr(position), new IntPtr(0));
  }
}

See the Platform SDK documentation for the TB_PRESSBUTTON message for more information.

I was wondering if anybody knows how to disable the version auto increment feature in Visual C# .NET???

Get rid of the asterisk in the AssemblyVersionAttribute typically found in the AssemblyInfo.cs file and use your own 4-digit versioning scheme. This is best for larger solutions anyway. We have our own scheme we used that I designed for the ~60-project solution I maintain. Especially with late-binding, automatic version is a real pain.

I tried that and set the version to 1.0.1.1 and when I built it it still incremented. Any ideas?

Would it be possible for you to share this system?

Heath Stewart2-Jun-04 11:49

Something else is wrong, then. So long as you have something like this:

[assembly: AssemblyVersion("1.0.1.1")]

You'll never have an incremental version number (and it's technically not incremental - see the attribute documentation in the .NET SDK). Also make sure that if you use the AssemblyFileVersionAttribute that you fix that as well, although I don't think that accepts an asterisk.

Make sure that you have project references as well instead of assembly references (when you add a reference, click the Project tab instead of selecting an assembly) and make sure that you have one and only one AssemblyVersionAttribute defined at the assembly level (prefixed with assembly:). You shouldn't have any problems. If you do, you have something wrong.

And, no, I can't share that system. It's our flagship product.

If you want the versioning system I use, it's almost the same as what the C# compiler uses. The major and minor versions (the first two) you set. The third is the number of days since January 1, 2000, and the last is incremented to signify minor changes. We don't change that number much except for minor bug fixes since Fusion requires that a new assembly version exists or it won't download it (we use touchless-deployment over the 'net). The build is typically the number of days from 1/1/2000 till the target release date so that we don't change it ever day.

Config Files ?

triso2-Jun-04 9:24

2-Jun-04 9:24

Hey Guys,

If I have created an App.config file in my project, and in that file specified a key and a value. Then coded the following :

string test1 = System.Configuration.ConfigurationSettings.AppSettings["Key1"];

tabPage1.Text = test1;

This sets the Text Property at the top of the Tab Page on start up to what i specified in the config file. Now i want to change the BackColor property of the Tab Page, but i constantly get the following error: Cannot implicitly convert type 'string' to 'System.Drawing.Color' ? Any assistance appreciated.

Heath Stewart2-Jun-04 9:53

2-Jun-04 9:53

You must use the ColorConverter to covert the string to a color, like so:

Color c = this.BackColor; // Default
string color = ConfigurationSettings.AppSettings["BackColor"];
if (color != null)
{
  TypeConverter converter = TypeDescriptor.GetConverter(typeof(Color));
  try
  {
    c = (Color)converter.ConvertFromString(color);
  }
  catch { /* Leave default */ }
}

You can also use the AppSettingsReader, but this is limited to reading types with a Parse method:

AppSettingsReader reader = new AppSettingsReader();
bool b = (bool)reader.GetValue("ShowInTaskbar", typeof(bool));

The first way I outlined is far more extensible and provides support for more types.

Thanks. What if I were to want to set the Alignment property of the TabControl itself ? I've gotten continuous errors with this as well.

Heath Stewart2-Jun-04 10:07

2-Jun-04 10:07

Again, a TypeConverter. Use TypeDescriptor.GetConverter(typeof(TabAlignment)) to get an EnumConverter. You might want to read-up on the TypeConverter in the .NET Framework SDK.

Cool, i'll read up on the type converter, since im guessing if i want to set any properties that are not strings, this is what i will be doing. Thanks for your help.

Heath Stewart2-Jun-04 10:21

Word of warning - not every type has an associated TypeConverter. Only those types that are attributed with or inherit the ConverterAttribute with a valid TypeConverter (or simulate this through the component model) work. Enums, primatives, and many structs support TypeCoverters. If you need something more encompassing, then forget about using the <appSettings> section and use a serialization approach, like using XML Serialization (see the System.Xml.Serialization namespace in the .NET Framework sDK). There are many articles here on CodeProject that discuss such an alternative. You could even create your own .config section and use XML Serialization to deserialize more complex types that may or may not have a TypeConverter associated with them. Just search this site for examples.

Can you group sections in a config file, such as

<configuration>
<appsettings>

<add key="LabelColor" value="Red">
<add key="LabelText" value="Test text">

I think you know what I mean. Can i group keys via a tag such as "label" for all keys refering to attributes of a label ?

Displaying selected items in listview on another form

2-Jun-04 11:59

You might want to encode your < and > with < and > next time.

You can group sections, but they must be accessed as part of a group. You really need to read about .config file. See the IConfigurationSectionHandler for good information and a start. Once you decide to group a section you cannot move it around.

For example, the system.web section is a group and there are many section handlers configured under it (configured in the machine.config file). They are all accessed as "system.web\sectionName". If you change the group they are in, you break the code.

I want to display selected items in a listview on another form. for example, I have a form with a listview, three textboxes (lastName, firstName, idNumber), and three buttons (Add, Save, View Form). When I click the view form I want the selected row of items to be displayed on another form that has three textboxes. I have tried many different techniques but none work. Does anyone know how to do this? Any help would be appreciated especially a coded example!!!!
