Does anyone has a sample code or idea for cutting and adjusting a picture size when it is uploaded thru picturebox?
For example..
1. Picturebox size on winform = 150*150
2. A picture size = 1024 *800
3. I want to be able to cut 150*150 out of 1024 *800 and upload it. I wish the cutting and adjusting size is possible thru winform.
Normally when user upload a picture, how do u control the size of the picture uploaded by the user?
is there a way to change the size picture (scale the image according my size 300 x 150). Let say an user upload an image with (500 x 300), using picturebox, can i scale the image (500 x 300) to my picturebox size so that it can looks perfectly nice?
I've a form set to size 1240:750. On my PC where I've VB2010 installed, the screen size is set to 1680:1024 and the form can be viewed fine but on a PC with screen size set to 1280:1024 (higher than the form) the form in question is cropped almost a third of it. To adjust the form to everyone screen size I set the below code at load with no avail.
'Autosize form to screen
Me.Height = (SystemInformation.PrimaryMonitorSize.Height) * (0.9)
Me.Width = (SystemInformation.PrimaryMonitorSize.Width) '* (0.9)
Me.MaximumSize = New System.Drawing.Size(Me.Width, Me.Height)
Me.MinimumSize = New System.Drawing.Size(1240, 750)
I've been reading gobs of articles on FTP upload in ASP.NET recently and they all seem to make sense, but every time I've tried implementing them I either get an empty file uploaded, or no file at all. Here are some of the articles I've been reading:Managing FTP Transfers from an ASP.NET Web Page By John Peterson FileUpload Control Doesn't Give Full Path...How to: Upload Files with the FileUpload Web Server Control I know exactly what the problem is but I don't know how to fix it. I can pass the file name from the FileUpload control, but the path does not exist for security concerns. However, the StreamReader object requires the fully qualified path of the file to be uploaded, so how the heck do I get that? I'm at my wits end!Let's use the example by John Peterson that I linked above. Here's the code:
Protected Sub btnUploadFile_Click(ByVal sender As Object, ByVal e As System.EventArgs)
Dim myFtpWebRequest As FtpWebRequest
Dim myFtpWebResponse As FtpWebResponse

I have a picturebox on a form. The image in the picturebox is actually a report. I want it so if the user clicks on it it will zoom larger --- while the picturebox remains the same size. Of course, the entire image will no longer be seen. So I also want to be able to drap this image around with the cursor. The examples I've found for picturebox zooming cause the picturebox itself to get bigger and smaller. I need it to be like an Access report. Click on the report and it gets bigger. Click again and it goes back to the full image. Does anyone know of an example or tutorial in VB.Net for this type of zoom-with-fixed-size picturebox function?
View 2 RepliesI have a picturebox with a tiled background image (plane white bitmap), and an "image" resource centered in the middle of it, I would like to chance the size of this centered image within the picturebox.
I tried:
picScaledRepresentation.SizeMode = PictureBoxSizeMode.CenterImage
picScaledRepresentation.Size = New Size(Width, Height)
But this just changed the the size of the whole picturebox, rather than the image within it.

View 1 RepliesI have a database application in which a user can add up to 6 pictures to each record. This pictures are not directly saved in the database but in a sub folder of the applicvation folder. Now, the problem is that lots of the pictures of users were taken on a digital camera with highest resolution - in these days it means that the picture files have a file size of 3MB.I would like to reduce the file size / resolution of the picture, so that the database can load and view this files more smoothly (I am not in need of a thumbnail preview, just want the pictures being a bit smaller).
The way pictures get attached / linked / 'inserted' to a database record is via OpenFileDialog. When a user selects a picture file it gets copied into the applications picture folder and renamed to the record ID of the actual record + number of the pic added.How could I reduce the picture size during adding it (OpenFileDialog / copying to folder)?
