i have a function which grabs images from urls, using this function:
Public Function webDownloadImage(ByVal Url As String, Optional ByVal saveFile As Boolean = False, Optional ByVal location As String = "C:") As Image
Dim webClient As New System.Net.WebClient
Dim bytes() As Byte = webClient.DownloadData(Url)
[code]....
All the examples ive found so far point at using imagemagik or another add in.
Anyways, i have coded a video downloaded and i want to include a converter as a separate exe file. But obviously people may have different file directories so a simple piece of code i have used won't work. This is what i have: Also where would i place the exe file?
View 3 RepliesI have an image that stretches to the size of my form so if the user resizes the form, the image resizes aswell. All works great apart from the constant flickering during the resize of the image.
View 4 RepliesThe object is to load an image into a picturebox, then save a new copy of the image in a different location, but with the height and width of the image box not the original file's height and width but I can't figure it out. I've got the loading and saving working no problem but getting it to adopt the new size is stumping me, it just keeps saving with the original file's size properties
View 2 RepliesI have a program that was created in VB6. I converted it to vb 2008. In the program there is a picture box that is pretty small. I had a command that would resize the picture box after importing an image. It no longer works.

I'm making a tileset creator and everything is working fine so far except previewing a tile. The way it works now is it gets the image from a picturebox and calls the following code when scrolling the mousewheel. It functions fine but there is a border appearing between the tiles and I can't figure out why. The source image is 32x32 in size. Most likely it is the graphics class not measuring in pixels or something.
Public Sub ResizePreview(ByVal dSize As Drawing.Size)
Dim bm As New Bitmap(TileImage.Image)
Dim pTile As New Bitmap(dSize.Width, dSize.Height,

Does anyone know if it is possible to resize an imagelist/listview image without repopulating the image list? I am using scroll bar to change the image size from 25 point to 256 point. When I leave the scroll bar the imagelist repopulates from the files list. This can be very slow when working with high resolution pictures. I don't want to limit the image size to 2 sizes by using large and small imagelist.
View 1 Replieshow I could make an application in visual basic 2008/vb2005 that detects when a new file is downloaded. One of my old time friends created the same app with visual basic 2008. It notifys you when your attempting to download a file. For e.g: I try to download "aim6.exe"
it will show a message: "C:UsersMATTST~1AppDataLocalTempsXx0Fd31.exe.part is attempting to be downloaded"
I think it uses a file system watcher.
I have an xml file that I download from a secure site every 5 minutes, I have the application set to download at 3 minutes after the hour so it runs at 3, 8, 13, and so on. The file is supposed to be there within a minute after the 5 minute increment has occured however this is not always the case, so I changed the download time from 2 minutes after the hour to 3 minutes. However I am still running into issues with it not being there even then. What I want to do is validate the downloaded xml file to ensure that the data is there and if it is not wait 10 seconds and rerun the download again.
if the file is valid it will call the SQL import Sub (),if not it needs to delete the existing file and rerun the download sub again.The problem I am having is that all the examples that I have seen when I google are for validating the xml file prior to upload or upon the xml files creation.
I have made a downloader in Visual Basic 2008, using the Webclient that is built in. This is the code i have to download the file[code]...

I have searched for almost a hour now, but i can't find the proper code for my purposes.
I am working on a website at the moment which is displaying a strange bug with generated word documents. The site has a feature on it which allows the user to download a word document containing information related to their visit. This file is generated via some vb.net code and takes an xml template of the final document and inserts the relevant content required.
The strange behaviour is that on some machines the .doc file generated displays fine and on others it displays as XML when opened in Word. Both behaviours have been seen in the same version of Office (2003) but on seperate machines. My question is really whether the error lies with the set up of word on the individual machines, or whether there is an error in the code.
The code to create the file and download it is as follows:
Response.Clear()
Response.ClearHeaders()
Response.AddHeader("content-disposition", "inline; filename=MyNewFile")
Response.ContentType = "application/msword"

I have recently programmed a site that enables a user to upload and download files to and from an FTP site.

I am trying to put something in my program so that when a button is pressed a file will be downloaded from a website. When that is done downloading add that folder to a location on the hard drive.
View 1 RepliesI'm just starting out with VB and have downloaded and installed VB Express 2008. I'm researching and trying to wrap my head around programming in VB before I start working on any projects. I have a little bit of experience with ASP Classic so some of the syntax looks familiar, but I can't get a handle on database integration. Let's say I am creating an address book. Each installation is a stand-alone (no network connectivity). How are databases used in this situation? Are they built using VB Express and packaged into the installer or can you create them separately (using either Access or MySQL) and then package them into the installer? What is needed to read and write to these databases? Are there extra bits of software that need to be packaged into the installer to allow access to the databases?
What if this application does connect to a centralized database (let's say a MySQL or Access database on a web server). Is the connectivity handled the same way? Sorry for so many questions, but I just can find the answers I'm looking for when searching. I'm not necessarily looking for the actual code to do this, just an explanation of how it's possible (or even a link to some examples/tutorials).
I am currently working on a project, which requires to download files from the internet and copy them to certain directory's... I've done the downloading part but I can't seem to get the directory working. The directory is "special" E.G. Appdata Program Files etc., and well when I tried just using %appdata% it seemed to create a new directory NAMED %appdata% rather than actually goto appdata...
View 6 RepliesI have a process serves as an application updater.It checks it's local cache of files and compares this against list of files online.On it's first run there are no files in the local cache and it therefore downloads ~100 of these files.[code]This appears to work very well, since Explorer confirms that all files are extracted and available.However when I later run this process again, it cannot verify the existence of 6 of these files and therefore tries to download them despite the fact that they are clearly both present and up to date.The offending code is a simple File.Exists call which appears to deny the local existence of these files, and therefore tries to get them again.The system continues to work well, but over time the continual downloading of these 6 files is going to get kind of silly.

View 16 RepliesI would like for a user to upload an image to a file in my web application. However, before being saved I want to resize the image to a specified size. I have found code on the Internet to do what I want but I am having trouble adapting to meet my needs. Here is the part I am having trouble with:
' Resize Image Before Uploading to DataBase
Dim imageToBeResized As System.Drawing.Image = System.Drawing.Image.FromStream(FileUpload1.PostedFile.InputStream)
[Code]....
Rather than upload to a database I want to save the image to a folder in my web application. The problem I have encountered is that VB won't let me save a byte() to a folder. Not sure what I can safely change to adapt for my purposes. Why does it need to be changed to a byte() in the first place?
I have an app that displays images (using picturebox component). what I am trying to do now is to try to allow the user to resize the image how he wants it (scale). for this i think I need to create an instanece (bmp) clone of the selected image in the picturebox and draw it ontop of the original picture; then specifi new set of size points.I was trying to use the code below:
Graphics.FromImage(PictureBox1.Image).BeginContainer('i do not know what to do here')
I need to specifi the new size of the graphics container but I do not seem to have any clue on how to do it.
How do I resize an image by the same scale? remember to mark the replies as answers if Welcome to the All-In-One Code Framework! If you have any feedback,

View 1 RepliesI am new with visual basic 2008 express edition. I wanted to ask on how to resize an image in a picturebox with a set height and width.[code]...
All it does is open a file with open dialog filters. I have a set height and width for the picturebox. If i open a picture with a height and width greater than that of the picturebox, the picture box will only display a portion of the picture.
I am trying to figure out how to go about my two problems i am currently having when trying to display a resized picture into a picturebox on my form.
What does it need to be in order to grab the image thats already been cropped in the pbCrop picturebox? I have the cropped image in the pbCrop picturebox and i then am trying to resize it.[code]...
I have a form where i load an image to a picturebox. I open a dialog to prompt the user to grab a file and once that is done i pull the image into a picturebox. Now i want to resize all incoming images but.... because of how it affects my ability to draw lines in the picturebox i am restricted to leaving the picturebox size mode set to normal. So i set out to write a resizing function.
The issue i am having is that eventhough i pass the function an image. I get the Height and with from the image object and it appears that i should be tripping some of my IF/Then statements ... neither Scl or Scl2 ever gets set which in turn keeps nw_height and nw_width from setting themselves properly.
All 4 of those variables stay 0 at all times and im not sure why.
