I already have a connection for my project; how do I use the sql commandtext and define the connection without going through the conn = MS jet; path etc. If I have to do the conn = ms jet, path, etc. will I be opening another connection to the same database?
Thanks for your time. Scott

And those would be??? Each cell can only hold a single value or object, so you'll have to provide a bit more detail as to what your talking about.

VS 2005 / Framework 2.0 allows you to store settings as User Settings and Application Settings replacing the older style App.Config in Framework 1.0. You can now publish your application and any updates can be forced to the end-user. Unfortunately when you publish the user settings that the client is able to change with my form and save, get wiped out to default. Also, if I setup Isolated Storage for the settings to be stored into, when I re-publish once the app has been in production for a while, it resets everything to default.
Am I missing something?  Microsoft gives you the capabilities to store a users own settings for their app, but boom when you republish, the settings get reset to default.
Any insight is appreciated..

I had this same problem with an issue. I decided it was easier just to store my values (I only had a few) in the registry by user name.
Hope this helps.

In VB2005, how can I dinamically create a Timer inside a class without using the control. I suppose that I have to use the System.Timers.Timer class but I don't know how to handle the Elapsed event.
Thanks in advance,

Do you mean something like this?
Private Sub TimerForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim Timer1 As New System.Timers.Timer()
AddHandler Timer1.Elapsed, AddressOf TimerEvent
End Sub
Private Shared Sub TimerEvent(source As Object, e As Timers.ElapsedEventArgs)
MsgBox("Hello World!")
End Sub
Trinity: Neo... nobody has ever done this before.
Neo: That's why it's going to work.

Just declare it withevents. Example: Withevents tmr as new timer

Yep thanks, I missed the WithEvents modifier.

I've been trying to find the best way to load data from SQL into a DataGridView. Obviously I could just load it into a DataSet with a SqlDataAdapter and set the dataSource of the DGV to the DataSet, but i'm having issues because there are 120,000 records that need to be loaded, and this takes quite a while to load DataSet from the adapter. I guess this isn't an issue with the DGV, but loading the data into the dataset.

Maybe you should only grab the number of records that you are going to display in the grid at a time?
|
|

Well i was going to have them be able to scroll through the list instead of forcing them to search for a specific set of records, but that seems to be the only way.
Thanks

I guess my only other suggestions for making it faster are to make sure that you are selecting ONLY the columns that you absolutely need in the grid, and to do everything you can (in terms of formatting) in the SQL statement so that you do not have to loop through the records to format after you have retrieved them.
Good Luck.

Agree.
Thanks Again.

I was wondering if anyone knows of an image editor that works with vb.net on windows XP. It would be like Kodak Image Editor but would work with XP.
I have tried to put a picture into a panel but the problem I have is that I cannot zoom the image (picture). I am looking for something that will enable me to change size of the image once it is inthe vb code. Just like the Kodak or is there a way to do this.
Help

I do not like using third party tools but if there is nothing else will have to go for it.
Is it simple to put into the vb.net coding and does it come as an icon on the vb.net component toolbox

Paint.NET comes with source code. You can see how they manipulate images.

This is trivial. Just draw the picture yourself, and use a scale transform on the Graphics object, change the scale according to whatever UI you want to control zoom.

I am capturing a file from a folder and displaying it.
How would I go about changing the scale as you suggestion as by now you will realise I have not got a clue. New to this.

Thanks Dave for the following, it works a treat and yes easy
*******
Easy. Drop the PictureBox control into a Panel control on your form and set the Panel's AutoScroll property to True. In your code, load the image you want into an Image object, then set the PictureBox's Image property to that Image object and set the Size of the PictureBox to the size of the Image or to any size to you want.
*****
My next problem was when I put the image (tiff) into the picture box it is huge, have to use the scrolls bars. It there any way I can make the image a wee bit smaller when loading to save me making the object take up the whole screen. With crystal reports you have a command like
CrystalReportViewer1.Zoom(1)
Also I use XP and just found out it does not work with Kodak Image Edit Control. Works great with Win 2000. Is there anything out there, free, that does the same as Kodak but with XP
Does this make sense?
