I didn't know you could write an msi in C#. So, all you need is System.IO.File.Exists to see if a file exists already ?

storing kannada values in access.while retreving also it showing boxes.
please Help to come out.

I can vaguely understand this, but not well enough to know what you're asking....
What is Kannada Direct ?
Yathish hatter wrote: problem is values in txtbox showing boxe
Oh, OK. I think the problem is that the textbox is not using a font that includes the characters that are stored. So, you need to set the font of the textbox to one that can display those values.

Hi
I am displaying a collection of objects in a datagridview by setting the datagridview's datasource to the collection property.
It works well, but now i want to display one of the properties as a combobox and not as a text field. I have found examples where one manually adds a new column and then setting it as a combobox, but nothing where the columns are automatically set from the properties of the object. Hope i make sense.
|
|

|

you have to manually add the ComboBox column.
try this
DataGridViewComboBoxColumn DGVcombo = new DataGridViewComboBoxColumn();
DGVcombo.HeaderText = "Combo Column";
DGVcombo.Name = "AnyName";
dataGridView.Columns.Add(DGVcombo);

Hi Guru,
I'm a newbie in C#, as i know i can get the MSIHANDLE by call MsiOpenDatabase from Win32 SDK, can i call this function directly or there is a better way to get MSIHANDLE.
|
|
|
|
|
Your best bet is to p/invoke the Win32 call.

As has already been said, you could use PInvoke. However, I think you could also add a COM reference to Microsoft Windows Installer Object Library and work from there (msi.dll or something like that)

I have a little app that will resize its main form when data is loaded. Sometimes I need to move the form so it remains entirely visible on the screen.
If the mouse cursor happens to be over a particular control when that happens I would like to move the mouse cursor so its position relative to the top left of that control remains constant. I can only seem to get the mouse location relative to the top left of the screen and I can only seem to get the control position relative to the top left of its parent.
Back in my MFC days there were two methods ClientToScreen and ScreenToClient that would convert between positions relative to the top left of screen and top left of the controls client area. Is there an equivalent in dot net?

Your control and window classes have a PointToScreen and PointToClient method.

I have a c# winforms app (must be a win app - responds to windows events) that accesses a web server side DB through a web app using a .ashx http handler that queries the DB into a dataset then coverts the dataset into XML and sends it back to the client.
My hosting service does not allow a remote DB connection (is this typical?) so I must do it this way.
Getting the server data into the client dataset is easy enough (ds.readXML) but is there an easy way to send back inserts/updates/deletes in the local dataset without coding all the SQL?
I know I can set up the generic insert/update/delete sql commands on the local DS but is there a way to get the actual resulting SQL statements and sent them to the server? or send the DS back as an object (the XML conversion loses the meta info on changed/inserted records)?

Thanks Xmen - but this is what I'm trying to avoid. I'm dealing with 5 or 6 tables and I was hoping to take advantage of the built in updating features of the DS as if it were local DS <-> local DB. It's early in development so I don't want to hard code field names for 5 tables. What I want to do just might not be possible.

It's not exactly what I was looking for but it did lead me to Diffgrams (http://msdn.microsoft.com/en-us/library/ms172088(VS.80).aspx) which is exactly what I was looking for.
This converts the DS to XML including the DS meta data on updates/inserts/deletes
Thanks for the nudge in the right direction.

I would assume that you have a reference to the DSO stuff in your project. Make sure it is marked "copy local" otherwise it will not be deployed.

Hi,
I have a ReadOnlyObservableCollection<t></t> being returned in an AsyncCompletedEventArgs derived object. Is there any way in the get; accessor to automatically pass it back to the original thread without having to use the Dispatcher in the callback method?
At the moment I'm doing this:
void SyncCompletedCallback(object sender, SyncJobCompleteCallbackEventArgs args)
{
Dispatcher.BeginInvoke(DispatcherPriority.Normal, (ThreadStart)delegate
{
ReadOnlyObservableCollection<synceditem> history = args.SyncJobHistory;
HistoryView.ItemsSource = history;
});
}
</synceditem>
I'd rather let consumers have easy access to the collection like:
void SyncCompletedCallback(object sender, SyncJobCompleteCallbackEventArgs args)
{
HistoryView.ItemsSource = args.SyncJobHistory;
}
Thanks,

I am working on a touch screen application and I am trying to add a button(s) that function as pageup/pagedown on a MDI Parent form with the child forms as the items to scroll.
I've spent entirely way too much time scouring the internet for a solution to this. I've tried multiple items that I thought would be the answer to no avail.
I really thought that this would be the answer:
SendMessage(this.Handle, WM_VSCROLL, (IntPtr) SB_PAGEDOWN, IntPtr.Zero);
I know I'm close, but then again, I could be way off!
Ideas?
I guess no one has a solution for this...
For those who are wondering...
Given the scope of the project and the fact that I had to use a MDI parent and children (specs from customer)and buttons to scroll (touch screen app), I used a method to give the appearance of scrolling by setting the location of each form in a foreach loop. It moves the forms as if it were scrolling.

Hi All,
I'm just wrapping up some functionality in a class that uses some third party components under the hood. My wrapper object by default subscribes to some events on the third party components and forwards them on to consumers of my wrapper class.
In general I would expect consumers to subscribe to these events most of the time, however, I can't always assume that and I also want to optimise my wrapper. What is the general consensus on coding around this? At the moment I always subscribe to the third party events and then each time one of these events fires I check to see if the event handler is null before forwarding on the event.
Is there a better pattern for this?
