Ex:

'font

Me.Font = New System.Drawing.Font("GeoSlab703 Lt BT", 8.25!, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, CType(0, Byte))

'color
Me.ForeColor = System.Drawing.Color.Red

use the 'font dialog' control and 'color dialog' control from the toolbox to allow the user to choose...

Graphic,DrawString cannot write a string

Hi all,
I'm trying to write shoot date on the images from exif datas. I'm using Graphic.DrawString but it's not working. Weird thing is, when debugging it writes but when running not! My code is very simple;

Dim f As New Font(FontFamily.GenericSerif, 8.5F, FontStyle.Regular, GraphicsUnit.Point)
Dim graph As System.Drawing.Graphics = System.Drawing.Graphics.FromImage(_img)
graph.DrawString(exifListBox.SelectedItem.ToString(), f, Brushes.Black, CSng(_img.Width) - 100.0F, CSng(_img.Height) - 30.0F)

Why it is not working when running?? Anybody has an idea?? Thanks...

Did you call Dispose() on the Graphics object (graph in your code) when you were done drawing with it?

You might want to include the code around this code. There's something else wrong we can't see because there's not enough code to show us what else is going on.

There is nothing around this code. But I solved this issue with adding
pictureBox.Image = _img
just after the graph.DrawString(...) Smile | :)

I guess my description of the issue let people think wrong D'Oh! | :doh:

Thanks so much for your interest..

Yeah, if you show the picture or put it in a PictureBox, THEN make changes to the image, the changes won't be seen until you assign the picture to the PB again or redraw the screen image of the bitmap.

Changes to the bitmap image are NOT automatically updated in the controls that are showing them.

BinaryFormatter.Serialize works well but BinaryFormatter.Deserialize throws an Exception

The Assambly lays in the same Directory like the DLL that is Serializing.

What can I do?

converse of "indexfrompoint"

The listbox has a member "indexfrompoint" that returns the index of the item at specific coordinates. Is there a reverse function that gives the coordinates of an item with a given index?

Sir/Madam,
Can I programically find out whether the particular table exist in the database or not.
Thanks abd Regards

you can do this by querying the DataSet's table-Collection with the method Contains.
e.g:
Dim ds As New DataSet

...

If ds.Tables.Contains("YourTableName") Then

...

End If

Yes, however the exact query depends on the database.

For example, in SQL Server 2000 the query

SELECT * FROM INFORMATION_SCHEMA.TABLES

gives you your starter for 10.

Hie guys. I am new to the forum but I hope it will be worthwhile to be here.

I need a project proporsal for any small system I can undertake as my college project. Others have been doing projects like Accounting systems, something to do with Intranet etc.

well I would prefer mine to be coded in VB6 if having a database the it should be SQL server database with something to do with the ineternet or intranet. please guys just send me anything. Any project that can be run in VB6.

My email is mtheprince@yahoo.com

Thanks

My first piece of advice is not to do this in VB6. VB6 is almost completely obsolete now. It was replaced in 2002 by VB.NET (almost 5 years ago, during which time versions 1.1, 2.0 and 3.0 have been released)

Be creative, there sure is something you can think of to build. My advice would be to go for either C# or VB.NET, since these languages are modern and the framework is new and better supported.

Its just that I dont have VB.Net as of now and need to get started. And the project as well. I can be creative but most of the projects are taken and need something new
