Is there a way that I can create images (bitmap, tiffs, whatever) from txt,docx,pdf,or rtf files?
One idea that I found was creating a Metafile from the file. However I am get GDI+ errors with the palette. how to get around that? Do you think this is the right track?
Dim
gr As Graphics = Me.picFile.CreateGraphics() 'i am really not using a picture box, but I thought if it helps, why not?

Ok I know this question has been asked to death but I still have not seen a good answer. I have created an application in VS2010 using VB.NET. In my application I have an error log that is an XML file located in the Public gstLocalErrorLogLocation As String = Application.StartupPath & "ErrorLog"that gets written to in the event of an error so I can trouble shoot application easier. My application also downloads files from our FTP site and puts the files in Public gstLocalDownloadLocation As String = Application.StartupPath & "download"So I have files that get read and written to as well and created and deleted all in the Application.StartupPath which is either "c:Program Files(Application Directory)(Some Directory)(Some File)" or "c:Program Files (x86)(Application Directory)(Some Directory)(Some File)" depending on 32bit or 64bit Windows 7.
After creating the setup I install it on my test machine that have both Windows 7 32bit and 64bit.Everything in the application works great till I have to write to, delete or creat a file in those directories above. I know it is an access issue and the UAC. This will get installed on numerous systems so the options I have seen to change file or folder permission on the computers manually is not an option.What has to happen is after I install the application it just works like when you install it on XP. Some post have suggested that you us a user with administrator privilages or group which is all fine and dandy but the user I have used to test the application has all of that.
So what I am asking is how do you create an application with VS2010 in VB.NET that after creating a setup package and installing on Windows 7 will just work with out "Access to the path c:Program Files(Application Directory)(Some Directory)(Some File) is denied." If I have to install this on 100 Windows 7 computers it has to be a concreate no manually doing anything just install and work like when we installed on XP.
I have two bmp files:
footer.bmp: 200 x 200
product.bmp: 1000 x 1000
I want to create a new bmp file with 200 x 500: Append the footer.bmp into the bottom of the new image - position (0, 300) Resize the product.bmp to 200 x 300 and position into (0, 0)How do I do this using VB.NET?
Dim oBitmap As New Bitmap(200, 500)Dim oGraphics As Graphics oGraphics = Graphics.FromImage(oBitmap)
I have a media gallery type project I'm working on, but I want to enhance it by creating animated thumbnails to "preview" the media. I have already created code to extract 10 incremented images from a pretty much any video format. Now that I have my images, I thought the most efficient way to animate them would be through a GIF. Once you have imported media to a library it will automatically generate the images, and hopefully create the gif thumbnail I'm looking for. How to generate animated GIFs in vb2010?
View 1 RepliesI have been learning VB2008 and have been working a little with the toolstrip. While this question isn't really urgent, I've been thinking down the road about images and image libraries that I would like to build and use in my programs. I am thinking I should set up my own library so that all programs I write will have the same look (at least as often as I want them to).
1) What does everyone use to create images? What programs, features, etc. are important? Eg. I have MSPaint and and old version of CorelDraw but have never really used them to high quality stuff.
2) Are people just using the images provided in VB2008 Pro?
3) What should I consider when working with images for use in Windows Forms programming? Currently I am not doing any web work.
i'm working on a project right now and I need to create a graphic library.The game I'm experimenting with is an RPG; this project is expected to contain many big graphic files to use and I would prefer not to load everything into memory at once, like I've done before with other smaller projects.So, does anyone have experience with libraries such as this one? Here's what I've came up with:
Have graphic library files and paths in an XML file Each entry in the XML file would be designated "PERMANENT" or "TEMPORARY", with perm. being that once loaded it stays in memory and won't be cleared (like menu-graphics)The library that the XML file loads into would have a CLEAR command, that clears out all non-PERMANENT graphics I have experience throwing everything into memory at startup, and with running the program running with the assumption that all necessary graphics are currently in memory.
This is my first attempt at creating a Winforms application, and I have been developing in the .Net Framework (Silverlight, ASP.Net, WPF) for about 6 months. So, my appologies if this is a newbie question.
Basically what I am doing right now is taking the drawings of a stylus-based input, and storing them into an image field in a SQL Server database. Then, in another form, I go and get that image out of the database, and load it into a picture box. It works, but it is rather "sloppy" how it got there.When the user clicks save, it stores that image into a temporary folder, then converts it to a byte array and throws it into the database that way. Then, it deletes the file from the temporary folder. When retrieving it, it pulls it out of the database in a byte array, then converts it to an image in a temporary folder, thus displaying it on the form.
Is there a way that I can just bypass the storing of the file onto the user's harddrive both times, and go from byte array to picturebox?
I would like to know how to enable my programs to rip image files off the web to display them in a picture box. all i know is how to use the web browser object to load the site with the image file on it

i would like to know how to now transfer that image from the web browser to a picture box or just save it locally

View 2 Repliesim using this MP3 tagging library called TagLib# or TagLibSharp.
Unfortunately the documentation is a bit patchy to say the least and their (Official) website, which contains all the documentation seems to have closed down, leaving me to download this MP3 tagging library from the link below.
http://developer.novell.com/wiki/index.php/TagLib_Sharp
Everything so far works, including tagging the 'Artist, Title, Album' etc. but I want to include an image in my MP3 files, like album art.I have found some sample code to read the image back from the tag using their library, I just can't work out what it would look like the other way around.
If filetotag.Tag.Pictures.Length >= 1 Then
Dim bin = DirectCast(filetotag.Tag.Pictures(0).Data.Data, Byte())
AlbumArt.Image = Image.FromStream(New MemoryStream(bin)).GetThumbnailImage(115, 115, Nothing, System.IntPtr.Zero)
End If
This code above will read an existing tag and load the image into a picture box called 'Album Art'.how to 'flip' it so that it would look something like ...
filetotag.Tag.Pictures = AlbumArt.Image
Obviously using the memory stream functions etc.

View 3 RepliesIs it possible to set the image windows displays when viewing a file created in a VB.NET application? In my case I have files saved that store info on football plays for a play creator program. Can I use the image of that play as what the user will see when he searches through windows explorer?
Let me further explain with an analogy: photo files in windows have their images displayed as the user cycles through them; he chooses which one he wants to doubleclick based on the thumbnail image of the actual photo. I'd like to have a "photo" of the play itself shown instead of what is now just a blank generic grey icon for the play files that I save.

View 1 RepliesI am attempting to add code to an existing script that will add the log messages to the log txt file in order to determine which loops are running in the script.

I am a beginner in vb 10 (vb.net). I am trying to create a text file "something.txt" and write a long string to the file. My string contains formatting chars newline and carriage return, which I want to keep.
I tried:
FileToSave.Write("test" & Chr(10) & Chr(13) & "test2", RichTextBoxStreamType.RichText)
using the System.IO.StreamWriter method but the line feeds and carriage returns are lost and all the text is just streamed together with no formatting.
Where 'FileToSave' is the path and name of the file. Note: I know I can use the vbnewline instead of chr(x) but this is not the issue.
i am making a simple form which can create the text file from the database table , for this , i am using this code at the load event of my form so that it can create the files at the load time.
IO.File.Create("C:Customers.txt")
IO.File.Create("C:Towns.txt")
IO.File.Create("C:Products.txt")
this code is working fine , but when i try to write my data in these file then the error come which is "the process cannot access the file 'c:owns.txt' because it is used by another process" i dont know where this file is used by my computer?
I am trying to write a program that writes information from texts boxes to a text file on the users hard drive.

Here is what I have so far:

I recently started having problems when creating new schema (xsd) files inside Visual Studio 2008. When I create a new schema file, the only file that is created is the xsd file itself. Neither the designer.vb or xsc files are created, which of course makes it unusable. The problem seems to be caused by the fact that the CustomTool property in the property grid is missing. If I change the CustomTool property to MSDataSetGenerator, then it immediately runs and creates the missing files noted above. How do I reassociate the CustomTool with Schema files?
