- Windows Forms General ToolStripMenuItem Shortcut on culture change
Hi
When I change the culture of my application I refresh the menu item's text. But how can I change the shortcut text which stays in the old language.
I tried to remove and set again "ShowShortcutKeys", the "ShortcutKeys" and "Visible" with no success. Invalidate() does also not help. The old language is kept.
Is it really necessary to create a new ToolStripMenuItem object
Thank you for assistance.

- Windows Forms General only allow user to select value 1 through 4 from listbox,textbox....?
I want to have the user select/input 6 values. They choose/enter 1,2,3, or 4.
I would like them stacked in a vertical fashion.
These values relate to a character string in a listbox
What is the best way to have these values lined up and limit the choices to 1,2,3, or 4
Thank You
ex: (listbox on the left, value on the right)
_____________

- Windows Forms General TreeView in User Control does not display initialized data
Hi -
I've been working on this most of the morning... I've created a Windows Form User Control that has a TreeView control. This user control is dropped onto a tab control in my main form. I initialze a TreeView node in the main form constructor as follows ...
MyUserControl myControl = new MyUserControl();
In the user control constructor, I create a node as follows...
MyUserControl() {
treeView1.Nodes.Clear();
treeView1.BeginUpdate();
treeView1.Nodes.Add(new TreeNode("Hello, node"));
treeView1.EndUpdate();
}
The node that I create - "Hello, node" - does not display in the treeView of my user control on my main form. I did two "sanity" checks... First, I can populate the user control treeView1 with manual data from the smart tag. This shows up on the main form (although I expected to see my "Hello, node"). Second, I created a "treeView2" in my main form. I used the same code to load "Hello, node" as above and this worked.
Setting a break at treeView1.EndUpdate() shows "Hello,node", as expected, but again, this does not show up on my main form user control. I've tried various techniques from other googles -
myControl.Enabled = false;
myControl.Enabled = true;
myControl.Refresh();
- all no joy.
Thanks,
Mike

- Windows Forms Data Controls and Databinding creating a dataview
I need to take a look at the content of some DataTable(s) I download from SQL Server in a purely debug situation. I decided to use DataView object for it. I improvised the following code:
DataViewManager mng = new DataViewManager ( sqlDatSet );
DataView dtview = mng.CreateDataView ( sqlDatSet.Tables[jj] );
dtview.BeginInit ( );
The jj integer is the index of a particular DataTable in a DataSet and is found in a for loop.
I expected a primitive form with a Table View displayng my records to show up. Is it not a reasonable expectation Nothing like this happened. The DataView remained an internal object. If I cannot get a good look at what is present in the tables I download I will be facing a cumbersome task of printing the stuff out via Console.WriteLine () or DEBUG.
I hope you understand my simple problem. Please help.
Thanks you. (Moderator: Thread moved to this forum for better responses)

- Windows Forms General OnClick
Hello,
I'm having a problem with a custom control derived from usercontrol. After I put up (and close) a modeless dialog box and then switch parent forms the control no longer generates or receives OnClick events. Other events like MouseDown MouseUp still work.
I'm wondering how the OnClick event is generated (I don't think it is a standard windows message derived event) and if anyone has any ideas how it could be blocked.
Thanks,
Jeff (Moderator: Thread moved to this forum for better responses)

- ClickOnce and Setup & Deployment Projects making a setupfile
I am making a program for a client of ours in Visual Basic Express.
The idee is that they put there daily incomes in the program and they send the database back to us.
I have tried to make a setupfile through publish.
However when I install the program on an other pc, I can't seem to find the database.
Does anyone know where this database should be
I have been searching for any mdf-files, but I can't seem to find the one I need.

- Windows Forms General Key-Based List Control? Hi Everyone,
I was just curious. Is there a Windows Forms List control out there that is "key-based". Basically, I want to display all of my Dictionary items in a List on a form, with the key of each item of the Dictionary being how I access each item in the List.
I've looked at the ListView and ListBox, but it doesn't look like either one would do the trick.
Thanks in advance

- Windows Forms General Webbrowser preventing enter firing
I have created an MDI which can display 2 types of child windows: a) windows form with textbox control (to display text files) and b) windows form with embedded axWebBrowser. If I only display multiple child windows of the file type, then I can click on any part of the window to bring that child window to the front. However, as soon as I also display a webBrowser type window, I can only change which child window is on the top by clicking on the window title bar, regardless of what "type" of window it is i.e. clicking on any other part of the form will not bring that window to the top although I can input data into that child window, even though it remains at the back. Once I have shown a webbrowser type window, the other child windows continue to exhibit this strange behaviour even if I close the webbrowser child.
Strangely, this behaviour is machine dependent - it works fine on one pc but displays the behaviour described above on another. Both are running IE6. I have checked all my internet options and cannot see any obvious difference.
Is anyone able to make any suggestions of how to correct this behaviour or why it is machine specific. I have searched the internet extensively but seen nothing similar reported anywhere.

Hi all,
I was wondering if its possible to redistribute certain dlls in the same directory as my program and for it to still work.
If this is possible, then how would I find out which ones are needed
Thanks Wilk06

If you application references the DLL's then when you deploy your application using Click Once then these files will be deployed as well.
If these are not referenced files then you can add them to you project and deploy the files as well.
It sounds as though its the first (your talking the ones which are needed for your application).
If your project builds and runs correctly - when you publish these referenced DLL's should be deployed with your application.

- Windows Forms General Form Opacity Changed -> Component not updatingFirst of all I apollogise for reposting this, but apparently I haven't posted it in the right place the first time. I hope that by posting here I could get an answer. So here goes:
I have created a form, and set the region of the form from a bitmap. On this form I have an PictureBox Component wich is updated by a timer. On the OnTimer Event I have some code that does the following things :
- Gets a region of the forms background and paints it on the control
- Gets 2 bitmaps from two different picture boxes and draws them on control
Everything worked fine until I decided to add the possibility to change the forms Opacity at runtime. The form is shown with 100% opacity at runtime and everything works as it should. When I change the opacity :
this ->Opacity = 0.7;
the form is made semi-transparent but the PictureBox stops updating. The odd thing is that when I hold the left mouse button pressed on the form, the control updates as it should.
I should mention that I have the following code, which is used to move the form, in the OnMouseDown event of the form :
int WM_NCLBUTTONDOWN = 0xA1;
int HT_CAPTION = 0x2;
Win32Calls::ReleaseCapture();
Win32Calls::SendMessage( this->Handle,WM_NCLBUTTONDOWN,HT_CAPTION,0);
I've tried forcing a form redraw at each update, but aside the flicker that it creates on each timer update, when the form is first shown, it has no effect whatsoever when the opacity is changed.
One last thing I should mention is that when I change at runtime the Opacity from anything to 100% things work once again.
Thank you for your answers,
Dragos

- Windows Forms Data Controls and Databinding combobox selectedvalue vs text question
Is there one method for getting a value in a comboxbox (DropDownStyle set to DropDown) regardless of whether the user entered or selected a value. My combobox is initially populated with a datatable and has a Value and Display member. Since a user can enter thier own value, it would not have a ValueMember, therefore SelectedValue fails. It seems I may have to test the SelectedValue and the Text properties for both validation and saving the data. I was hoping there would be an easier way.
Also, I just noticed that I may not be able to use the DataBinding properties from my bindingsource because if I bind using the SelectedValue, if the value isn't in the list then it doesn't show up. If I use the Text, everything works but I can't leave the control, let alone close the form. It seems to get hung.

- Windows Forms General Putting text on an image on a form
I am an old C/C++ programmer that is trying to learn C# and .net. I need to take text from a .txt file and display it on a form in graphics. I eventually need to save the image to a .jpg file.
I created a picturebox (is this the right object to use ) on the main form, opened the .txt file and read in one line at a time. Now I need to put each line of the text into the picturebox area in graphics mode to display it on the screen in the same order as the text in the file.
Any suggestions
Thank you

- Windows Forms Data Controls and Databinding Problem with RowChanging event
Hi,
if have a DataSet (SQLExpress) whith 2 Tables.
On one table I add a RowChanging event handler.
When I add a record in a boud datagridview then an exception occures in the handler. (After changing the postion in the DGV the event is fired).
Here my handler:
| |
void PCs_RowChanging(object sender, DataRowChangeEventArgs e) {
if (PCsBindingSource.IsBindingSuspended) {
return;
}
try {
MessageBox.Show(e.Action.ToString());
}
catch(Exception eX) {
MessageBox.Show(eX.Message);
}
}
|
I get and "Index out of range" exception and my DGV is a red rectangle with red lines across it.
After the exception I can see my MessageBox telling "Add".
For changes the things work fine - but the Add makes problems if I show the Messgebox - if I do nothing (comment out the messagebox)- no problems occure!
The error comes up even if I only call MessageBox.Show("Hello");
Here is the stacktrace of the error:
************** Exception Text **************
System.IndexOutOfRangeException: Index 2 does not have a value.

- Windows Forms Data Controls and Databinding cannot view data in datagridview
I've tried using the code below to view data from a select query in a datagridview control (along with several other methods) with no success. It is slightly adapted from a BOL example. The bindingnavigator appears to be reading the bindingsource ok (shows correct number of records) however, the datagridview remains blank.
Private Sub GetData(ByVal selectCommand As String, ByVal connectionString As String)
Dim VwTblDataAdapter As SqlDataAdapter
Try
' Create a new data adapter based on the specified query.
VwTblDataAdapter = New SqlDataAdapter(selectCommand, connectionString)
' Create a command builder to generate SQL update, insert, and
' delete commands based on selectCommand. These are used to
' update the database.
Dim commandBuilder As New SqlCommandBuilder(VwTblDataAdapter)
' Populate a new data table and bind it to the BindingSource.
Dim table As New DataTable()
table.Locale = System.Globalization.CultureInfo.InvariantCulture
VwTblDataAdapter.Fill(table)
Me.BindingSource2.DataSource = table
' Resize the DataGridView columns to fit the newly loaded content.
Me.DataGridView2.AutoResizeColumns( _
