- ClickOnce and Setup & Deployment Projects Web Publishing with multiple connection strings
Hi,
We have two environments available to all users, one for testing and user training, pointing to a database and a live environment pointing to another database. A third is on the developer machines and we all have our own DB running locally. I publish to two different locations for users (live and test) and two links on the users desktop point to either environment, which need different connection strings.
Here's my problem:
Before publishing, I change the connection string to say "Data Source=testserver", but when users start the test app it will fail and the log says:
**********
http://d9k2cn1j/Golfbreaks.TheClubhouse/Test/Golfbreaks.TheClubhouse_1_0_0_6/Golfbreaks.TheClubhouse.exe.config did not succeed.
**********
But if I had left the connection string as "Data Source=(local)", which is where my Dev DB is, it works fine.
Also, if I change the .config file from "(local)" to "testserver" after a publish in the source directory , the database still points to (local)!!!
Any ideas how I could somehow tell the publisher to use a different .config file depending on where I'm deploying to
Many thanks for your time if anybody could help us.

The problem is that the current directory in the custom action seems to be the system32 folder. Does anybody have an idea how to access the folder where the MSI package actually is situated from the custom action

- Windows Forms General Getting a form to appear only once
Hi All,
I have a windows 'Master frame' in which a number of forms can be instantiated (upon the selection of a menu item, or pressing a button in the master toolbar. All of these can be moved around within the boundaries specified in the master frame.
However, I don't want the user to be able to instantiate two instances of the same form in the frame! (E.g. One form is for "Student Details". If they press the student details button once, the form will appear. If they press it again, another form will appear.) Is there an easy way to do this (say in the properties of the form object) Also, if the form already exists, I would like it to set focus to the existing form.
Thanks heaps

- Windows Forms Data Controls and Databinding Assign Value to unbound DataGridViewComboBoxColumn
Hi, i have a problem vith comboBoxColumn. i want to assign a value
to unbound comboBox cell and when i change its index want it to fire an event. I use CellFormatting event to assign value like below
private void dataGridView1_CellFormatting(object sender,DataGridViewCellFormattingEventArgs e)
{ //(unVisibleSourceColumn is unvisible and belongs to bound dataset)
if(dataGridView1.Columns[e.ColumnIndex].Name.Equals("comboColumn")) {
e.Value = Convert.ToString(dataGridView1.CurrentRow.Cells["unVisibleSourceColumn"].Value)}
}
At that point, assign unVisibleSourceColumn's value to combo just for new row . Registered SelectedIndexChanged event for combo in EditingControlShowing . The code in combo_SelectedIndexChanged is below
private void combo_SelectedIndexChanged(object sender, EventArgs e)
{
UpdateDataSetsUnVisibleSourceColumnValue()
// here just updates value of currentRows unVisibleSourceCells value for bound dataset
}
After this, the program seems to enter infinite loop because of CellFormatting (P4 CPU %100 and crashes)
My question is, why it calls CellFormatting continuously except just one time and if anyone have suggestion for that case:
datagridView is bound to a dataset, an unbound DataGridViewComboBox is added, want to add first value
to combocell according to sourceColumn in dataset and when changing index of it, updating sourceColumn value. Thanks to everyone..

- Windows Forms Data Controls and Databinding ErrorProvider time-delays
Several time-delay properties are exposed for the ToolTip component - AutoPopDelay, InitialDelay, ReshowDelay. These properties are not members of the ErrorProvider class. It seems as though they might be available somehow because the ErrorProvider displays what look like ToolTips, but I can't find the technique. Is there a way
Thanks,
Gus

- 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

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 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 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 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)

- 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)
