Getting a user control to act as a container is pretty easy :
After creating a user control in VS 2005, the class code should look something like this:
<br />
Public Class MyUserControl1<br />
<br />
End Class<br />
Just add the following attribute to the class :
<br />
< System.ComponentModel.Designer("System.Windows.Forms.Design.ParentControlDesigner, System.Design", GetType(IDesigner)) > _<br />
Public Class MyUserControl1<br />
<br />
End Class<br />
That should do the trick 
If you (or anybody else) find a solution to my problem (read my first post in this thread), please let me know... PLEEEEEESE

Take a look at my TaskPane control, here:
http://www.codeproject.com/useritems/MSOfficeTaskPane.asp[^]
It does what you're asking. You can see how to set up the designer control properties to get everything to behave the way you want.

Thanks for your post, but it doesn't help me.
I only need a user control (not a custom control) where I can control which panel is the container for the .NET form designer.
Also seems like the entire Taskpane control acts like the container and not just a limited area within (panel)... controls can be resized and moved to overlap the toolbarfor example.

I'm trying to understand form.resx files. Particularly what is put in them and why. I have found plenty of information on resx files in general, but I am looking specifically to understand the relationship between the Visual Studio form designer and the form.resx files.
Most of the little I have seen on the topic says that the file is to facilitate localization and something about storing images for the form. The link to localization is definitely real, since when I select a different location I get another resx file for that location. Based on that, I assume that the default resx file is tied to the default location.
The specific issue that has me interested in this topic is as follows:
I have created a customizable form framework that allows users to filter a huge list of properties down to the ones that they care about. The initial list of properties is generated by reflecting on the business object that the form edits. Another form allows them to shift properties from a list to show and a list to hide. A custom attribute called ControlDescription can decorate the business objects' properties to specify the type of control to show, and additional information such as a domain to populate values in a drop-down list. A FormConfig object keeps all of the form customization settings, which consist of a series of show and hide property lists for the various business objects.
So what does all this have to do with resx files? Well, the forms are serializing the FormConfig object into the resx file. More accurately it is serializing each item in each list into the resx file. These lists are pretty long because the business objects have so many properties, which is why all this madness was developed in the first place. Anyway, I can't figure out why it serializes this particular object into the resx. It seems to be causing problems, because the resx files are getting corrupted on a fairly regular basis.
A typical (slightly absurd) error is:
Object of type 'Us.Fed.Fs.Nris.Nrvs.BusinessObjects.ControlDescription' cannot be converted to type 'Us.Fed.Fs.Nris.Nrvs.BusinessObjects.ControlDescription'.
My hope is, that if I understood what the resx is doing and why, that I can either prevent it from serializing these objects by restructuring the application, or avoid whatever is causing the corruption of the resx files.
Thanks,
Preston

I created a small windows which has a textbox and a button.
I want to make the cursor is in the textbox when the windows loaded, so users can easily input there. No problem I got to made it. But now I want after user input some text, they could push the button by just press enter on keyboard ( without press tab before enter ).
Which property should I change?
Thx in advance

I think there a property AcceptButton on the form which you set to the button you have created. At least that is how it is done in VB.net.
|
|
|
|
|
Yes, there is such property of the Form class
|
|
|
|
|
You would handle the keypress event on the textbox, and if it's a return, you would call the method to close the form.

Using the AcceptButton property on the Form is much easier than this (as long as there is one single global AcceptButton for the Form).

Apart from that AcceptsReturn property of the textbox should (and it is by default) be false. Otherwise pressing Enter will insert new line in the textbox

Hi,
Below is the code snippet showing how we can insert, update and delete records using ADO.NET with DataGrid control.
-------------------------------------------------------------------------
BEGIN CODE
Private Const SELECT_STRING As String = _
"SELECT * FROM Contacts ORDER BY LastName, FirstName"
Private Const CONNECT_STRING As String = _
"Data Source=Bender\NETSDK;Initial " & _
"Catalog=Contacts;User Id=sa"
' The DataSet that holds the data.
Private m_DataSet As DataSet
' Load the data.
Private Sub Form1_Load(ByVal sender As Object, ByVal e As _
System.EventArgs) Handles MyBase.Load
Dim data_adapter As SqlDataAdapter
' Create the SqlDataAdapter.
data_adapter = New SqlDataAdapter(SELECT_STRING, _
CONNECT_STRING)
' Map Table to Contacts.
data_adapter.TableMappings.Add("Table", "Contacts")
' Fill the DataSet.
m_DataSet = New DataSet()
data_adapter.Fill(m_DataSet)
' Bind the DataGrid control to the Contacts DataTable.
dgContacts.SetDataBinding(m_DataSet, "Contacts")
End Sub
Private Sub Form1_Closing(ByVal sender As Object, ByVal e _
As System.ComponentModel.CancelEventArgs) Handles _
MyBase.Closing
If m_DataSet.HasChanges() Then
Dim data_adapter As SqlDataAdapter
Dim command_builder As SqlCommandBuilder
' Create the DataAdapter.
data_adapter = New SqlDataAdapter(SELECT_STRING, _ CONNECT_STRING)
' Map Table to Contacts.
data_adapter.TableMappings.Add("Table", "Contacts")
' Make the CommandBuilder generate the
' insert, update, and delete commands.
command_builder = New SqlCommandBuilder(data_adapter)
' Uncomment this code to see the INSERT,
' UPDATE, and DELETE commands.
'Debug.WriteLine("*** INSERT ***")
'Debug.WriteLine(command_builder.GetInsertCommand.CommandText)
'Debug.WriteLine("*** UPDATE ***")
'Debug.WriteLine(command_builder.GetUpdateCommand.CommandText)
'Debug.WriteLine("*** DELETE ***")
'Debug.WriteLine(command_builder.GetDeleteCommand.CommandText)
' Save the changes.
data_adapter.Update(m_DataSet)
End If
End Sub
END CODE
-------------------------------------------------------------------------
You may make some more enhancement in the code. For example, you may check the DataSet's HasChanges method to see if there are any changes been made before you go to create a new SqlDataAdapter and SqlCommandBuilder. It may also be more efficient to save changes grouped by type: all inserts, all updates, all deletes. The basic program, however, is trivial and is perfectly adequate if the user won't make a huge number of changes.
Hope this helps  .

Hi, new to C# but getting there, need help on the following:
I have a MainForm with three panels on it, top, left and bottom. When I click a button on the MainForm the left panel gets a new form displayed in it with buttons on it. What I need to know is how to I change the top panel's controls in the MainForm when this buttons are clicked on the SecondForm that is displayed in the LeftPanel on the MainForm.
Thanks

My application has one MDIparent (say MDIparent.cs) and a tool form (say mainform.cs).
A text box in the mainform.cs takes some strings as input and displays the resulting data on the form. There are thousands of strings that can be entered in the input field that give different data for that particular string.
After entering my first string in the mainform, i open a "new" form in the MDIParent (File-->New) to give me another window of form so that i can calculate data for a different string.
However, when i do that, the application seems to be over-writing the data of the new window onto the first form and vice versa.
My goal is to keep keep the data different for different strings, separate.
Is it a problem with MDIParent or form?
Can anyone give me an idea how can i make sure that the form only subscribes to the proper event on itself alone?
Thanks

This is a bit help for the people who needs to translate the tooltip text of the CRviewer buttons and the dropdown text of this, here it is:
<br />
public void Translate(CrystalDecisions.Windows.Forms.CrystalReportViewer cr)<br />
{<br />
foreach (Control control in cr.Controls)<br />
{<br />
if (control.GetType() == typeof(System.Windows.Forms.ToolStrip))<br />
{<br />
foreach (ToolStripItem item in ((ToolStrip)control).Items)<br />
{<br />
switch (item.ToolTipText)<br />
{<br />
case "Export Report":<br />
item.ToolTipText = "Exportar Informe";<br />
break;<br />
case "Print Report":<br />
item.ToolTipText = "Imprimir Informe";<br />
break;<br />
case "Refresh":<br />
item.ToolTipText = "Actualizar";<br />
break;<br />
case "Toggle Group Tree":<br />
item.ToolTipText = "Agrupar";<br />
break;<br />
case "Go to First Page":<br />
item.ToolTipText = "Ir a primera pagina";<br />
break;<br />
case "Go to Previous Page":<br />
item.ToolTipText = "Ver pagina anterior";<br />
break;<br />
case "Go to Next Page":<br />
item.ToolTipText = "Ver pagina siguiente";<br />
break;<br />
case "Go to Last Page":<br />
item.ToolTipText = "Ver ultima pagina";<br />
break;<br />
case "Go to Page":<br />
item.ToolTipText = "Ver pagina";<br />
break;<br />
case "Close Current View":<br />
item.ToolTipText = "Cerrar Informe";<br />
break;<br />
case "Find Text":<br />
item.ToolTipText = "Buscar texto";<br />
break;<br />
case "Zoom":<br />
((ToolStripDropDownButton)item).DropDownItems[0].Text = "Al Ancho";<br />
((ToolStripDropDownButton)item).DropDownItems[1].Text = "Pagina Completa";<br />
((ToolStripDropDownButton)item).DropDownItems[10].Text = "Personalizar...";<br />
item.ToolTipText = "Aumentar";<br />
break;<br />
default:<br />
break;<br />
}<br />
}<br />
}<br />
}<br />
}<br />
<br />
I hope you find it useful, due to the other way is coding the buttons,

Hi iam facing an error when iam using
file.copy(filepath,destinationpath,true)
It gives me an error:
File.Copy(filePath, ArchivePath, True) Run-time exception thrown : System.IO.IOException - The target directory already exists.
Any ideas
|
|
|
|
|
first check if the file already exists or not
File.Exists(path2)
if yes then prompt message if user reply yes
then remove it first and then copy
Best Regards,
Chetan Patel

Are both filepath and destinationpath parameters a fully qualified file name or is destinationpath just the target folder? File.Copy can only copy files, so both parameters need to be fully qualified file names.
Look at the File.Copy Method (String, String)[^] docs, specifically at the IOException information listed under the Exceptions section.
You will get this exception if an I/O error occurs (unlikely) or the destination already exists, which is what is happening here. You can either do a File.Exists test before the copy and only copy if the file doesn't exist, or use the File.Copy(String, String, Boolean) form and pass in true as the boolean value to indicate that you want to overwrite the file.
