Thanks for your reply.
In fact, I want to develop a application which can play flash movie when the user click a hyperlink.
I have flash player. But I don't know whether I can call Pocket IE to run the flash player to play the movie.
Please give me some advices.
Thanks a lot!

I think all you would have to do is use the Process class to launch IE, giving the full path to the .SWF file as a command line argument. You can find the docs on Process.Start, along with some samples, here[^].

I have tried Process.Start. But it cannot be used in .NET Compact Framework. Any other choices?
Thanks!

Hello,
I am working on a case that would be so painful and time consuming if, there is no such way of doing what i need to do automatically. As you may very well know, applying the same action on a large number of images in photoshop and imageready is pretty easy, as well as it could be extremely tricky at times. Could VB.NET my saviour? 
What i need to do is to open files from a number of directories which has the same basic subdirectory construct in which the image file is contained, embed a transparent copyright layer, and export the opened files to their original directories optimised, with a different filename. (The code could do it one at a time. Doesn't have to bulk edit the files.)
This process is something i normally do on a daily basis using my pre-recorded actions in Photoshop 7.0 but with one important difference: this time i don’t have the chance to bulk edit files because they all have the same filename and they are placed in different directories.
I think it would be much better if i give examples at this point:
What i have is a directory with several directories in it, categorized by consept names. In every category named directory there are several different directories with numbers in the end for various contents. The very last of this chain is a directory called XYZ. The image i have to edit is, in XYZ directory.
So the hierarchy would be like:
pictures>>cars>>car1>>XYZ>>image1.gif
pictures>>cars>>car2>>XYZ>>image1.gif
pictures>>cars>>car3>>XYZ>>image1.gif
So the image names are the same and they are located in the same directory hierarchy categorized by directory names.
What i need to execute is to open all the files i have to edit, make my edit then export them (save optimized as) in the same directory with a different filename such as image1D.gif.
Is there anyone to help me with a sample VB.NET code for this purpose? Or is there any kind of tutorial i could use for building image editing/processing applications in VB.NET?
Thank you.

Read my C# articles on image processing, but I think all you need to do is create a bitmap with your copyright message, and a magenta or limegreen background, draw it over your bitmap using a color key, then save them out. Quite a trivial exercise.

Have you tried copying the .TXT file to the SQL server first, then running this statement?

I am kindda lost, how do you copy .TXT to SQL server, somehow they gave this error
Server: Msg 4861, Level 16, State 1, Line 1
Could not bulk insert because file 'y:\pricefile\test1.txt' could not be opened. Operating system error code 3(The system cannot find the path specified.).

OK, suppose your SQL Server is installed on one machine. It recognizes the C: drive only on the machine it is residing on. It will not recognize the C: drive on a client machine. So trying to load a file with a path "C:\test1.txt" when the file is on the client will not work, because the SQL Server looks on it's own C: drive for the file and the file does not exist. If you need to run the action from a client, the SQL Server needs to recognize a mapped drive on the client. If you copy the file to the SQL Server machine, use C:\Test1.txt. If your file is on your local machine as C:\Test1.txt, AND your local C: drive is mapped to the SQL Server machine so it recognizes your local C: drive as "Y" then use Y:\Test1.txt.
Hope that makes sense?

I'm making a program in VB.NET to manage concerts, but the problem is that each concert would have it's own database fields since each concert has different kinds of expenses and whatnot. So I thought in order to do this, I could figure out how to create new tables using the language, but I can't seem to figure it out. I've looked through my teacher's manuals and can't seem to find the code for it. I'm using an OLE database made in Microsoft Access.
I found something called datasetname.tables.add but I don't really know how to use it. If someone could help me, I would appreciate it.

How much do you know about databases? Databases don't have fields and you should not create a table for each concert.
Instead of looking VB manuals, maybe you need to look at some books that explain relational databases, how information is stored in tables, and how the tables are related to each other. If the database is created correctly, you should not have to keep adding tables to it.

That's about a vague a question are you can get. What reports? Generated by what? Crystal Reports? Excel? Access?
Without further information, there's nothing we can do to help you.

This could be a million different products by any number of manufacturers. You're going to have to get with the manufacturer of your software to see what interface there is for generating the reports you want.

Hi,
I am trying to make a font bold at runtime but I can not work it out.
I am currently changing the color of the font using:
lblPageStatus.ForeColor = System.Drawing.Color.Red
How can I do the same to make it bold?
Thanks
Shawn

u have to need creating a new font, then use that. Dont forget The Bold property of any Font is ReadOnly
Dim newFont as new Font (previousFont.Name, FontStyle.Bold )<br />
lblPageStatus.Font=newFont
|
|
|
|
|
Thanks for the reply. I will give that a go. It does seem a little odd that you have to create a new font to change the bold property, when you can just set a color without having to create a new font. Oh well. Thanks again!
Shawn

It's not odd if you understand the difference between selecting a font and drawing one. When you change the type to Bold, you're actually changing the shape of the Font. If the Font includes a bold version, then you're actually selecting a new font just by changing the style. For instance, a font can include a normal version of the character outlines, italics version, bold version, italics and bold version, underline, ... Now, if you selected a bold version of a font and the font file don't have a bold version, it can be calculated, or approximated. In either case, a new set of outline coordinates are used to draw the font. This is why properties like Bold are ReadOnly. Now, changing the color doesn't change the coordinates of the outlines that are drawn, so you can change the color all you want without regenerating the coordinates again.
