I have been looking all over the internet for the answer to this question: How do you save an Image (actually a Bitmap) to an ImageList at runtime? I have an extremely simple image editor that I created to make the images I require for another program. I have incorporated the image editor into the other program. However I cannot figure out how to save user-created images in the ImageList I am displaying via ListView. If I am aimed in the right direction, I can usually find my way through the maze.Additionally, I may need to know how to select that image (I may be able to figure this out later).
I am allowing users of the admin panel of my website to upload photos, its a simple process where I check the validity of the image and then save it to a folder, then I also have to record a couple of database records for that image to be able to retrieve it later, my saving function is as follows...The function that uploads and saves the picture in the folder with a name i construct in another function: [code] and the function that creates the database record for that same picture: [code] Now I know that what I am doing is full of best-practices violations, so please point me out to what I should do, keep in mind that the users might delete the pictures later, so I wanna make sure that I can delete the database and file of the picture, and the whole issue of the path.
Saving an Image to An SQL Database from a Visual Basic ASPNET.rtf?written in Visual Studio 2008, which is supposed to Insert Images into an SQL Database in Visual Basic ASP.NET I know it contains some errors but I can't point out exactly where I got it wrong?
I am attempting to save a graph that I have displayed on the screen as an image file (e.g., a jpeg file) but the image I want to save has additional information such as axis labels that are not displayed on the screen. In addition, I also want to suppress some information that appears on the screen.
I create a separate bitmap canvas called mycanvas and I recreate my display on this canvas with the additional information. When I save it with an image format such as iftype=system.drawing.imaging.imageformat.tif with the command mycanvas.save(filename,iftype), I get the image file that I created on mycanvas. But If I use the SaveFileDialog followed by mycanvas.save(filename,iftype) I merely save the image displayed on the screen. It is as if my graphics object has reverted back to the graphics object I was using for the screen display.
I have used couple of images on various button and label controls. I imported them by "Add Resources" window from project properties window.Everything is quite well at design time. But at runtime, no image is shown on those controls. I tried it from properties window. Then also tried from runtime by using "Button1.image=My.Resources.ImageName". But all are in vein.I did not change that application directory.

When I set the button background image in properties, it looks great. When the button is clicked, the image needs to change. I tried to use an image list like this: btnSample.BackgroundImage = ImlStimuli.Images.Item(0)and I tried loading them from a file. I can get them to read, but the image always turns out blurry or distorted. I've tried all variations of alignment, BackgroundImageLayout like stretch/zoom/centered, and I changed flat style, but nothing has worked. Is there a setting or something that I'm missing in properties?

In a VB.NET winform App I want to place icons on each tab header of a TabControl.I set the ImageList property of the TabControl and for each Tab I set the ImageKey property.My icons show as expected on each tab at design time within the IDE but when I run the App, my icons don't show (an empty space is shown instead).
I have a Form1 where i can add usercontrols during runtime. I draw their appereance in the OnPaint event using the GDI+ engine. The greate part is that i want to be able to resize these images during runtime wich goes pretty well now cause i draw points in percentage of the control. Unfortunetly it is very difficult to draw nice images/drawings ect with the GDI+ engine. Is there any other way in doing this?
Am new here and also a beginner in VB. I have created a form with a TabControl and when I click the tab page it creates another TabControl Dynamically.

I am not a total newbie to Visual Basic. However, the last time I used it was back in the days of DOS and Windows 3.11. Now I am using VS10 on a Windows Vista machine and it so different, I feel like a total newbie.
I am working on a project that I wish to load RTF files into a RichTextBox and an accompanying image into a PictureBox at runtime. I want this to happen when the user clicks a Menu Choice.[code]....
I have a 3 textbox;fname, mname and lname.As soon as I click button "add entry", the fname,mname and lname will be save to database to its first name, middle name and last name column respectively.
I want to add another set of 3 textbox during runtime , when i click button "add textbox", so that there are all 6 textbox in all. And I can add 2 first name, 2 middle name and 2 last name at the same time to my database.
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?
