VS 2010 Display An Image In Windows Form?
Jun 14, 2011
I'm using VB 2010, accessing a MS Access database. I have constructed a simple Windows Form returning data from the db, one field of which has a reference to an image I'm trying to display together with the data from each individual record.
I have a field with a product number, that matches the jpg file name (ie, the product number 5505 matches an image that I want to display, namely 5505.jpg). I've even created a new field in the db called 'Image', that contains the full name 5505.jpg.
So, I've connected to the db with an OleDbAdapter, and all the data fields are displayed via bound textboxes. I've been able to display a single 'set' image with a PictureBox, but I'm not sure how the make the connection between the returned data (txtSearchImage which is, say, '5505.jpg'), and getting the Windows Form to display this.
Am I on the right track using a PictureBox? I've tried binding this via the PictureBox properties to the relevant data field, but (obviously) it doesn't make the connection to the image file on my hard drive.
Here's my code so far:
Public Class Form1
Private Sub btnSearchKits_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSearchKits.Click
' The following line passes the value the user enter for state

I had created a windows forms application in vb.net. It contained several windows. Now the users of that application are telling me to display all in one main form. They want to see all the details in one form. I had implemented MDI but they want something like tabs. On different tabs different forms should be displayed. How shall I implement this.

So my program is supposed to lookup the image name from a database and display it in the form. Here's the
name = rs.Fields("image").Value.ToString
If Not IsDBNull(rs.Fields("image").Value) Then
If rs.Fields("image").Value = "" Then
Else
PictureBox2.Image = Image.FromFile("\MY.IP.ADDRESS.HEREwwwrootimagesproducts" & name & "")
End If
[Code]...
Now here is the problem: If the database returns the image name but the image cannot be found in the path specified, the app crashes. Is there a way to write an If statement to check if the image file exists in the directory specified?

I'm trying to recreate this feature for a twitter control program using VB Studio 2008. I want the users to be able to sign up their account in my application so they don't have to go to the site and do it.
Because captchas are dynamic images, I cannot pull the image from a src file. I'm pretty new to vb.net so, how would I initiate a session, with the webbrowser control or webclient, and be able to display the captcha image for that session on my form.

I am designing an app and I want to attach some pictures to my VB forms. I have used a picture box and the image is only visible before I debug. Once debugging starts, the image disappears.
How do I display the image when I run the debugger?

Shading some areas of a clock's image based on the time.I have successfully shaded some regions based on the start time and end time. But I wish to add a facility so that when the mouse is moved upon a shaded region(there will be atleast 2 shaded regions), I would like to display a message corresponding to that region.

I've been trying to make an image viewer that keeps top most while I do other things (like typing, etc), so I don't have to hop windows, or sacrifice screen real estate.I made a main form, and a configuration form (opened by pressing o), with options to set the main form's opacity (working), the picture displayed (as the form's backgound picture, not working), and if the main form stays top most or not (working).
Instead, the form just keeps displaying the image I set in the IDE.I first used a picture box to display the picture, which did not work, and decided I didnt need to have a picture box if I set the picture as the form's background picture.I tried looking at what could be going wrong, but couldnt find out much more than the path is being delivered to the main form.I'm working on Vista Home Premium 32bit SP2, VS2003, and here's the code.PS The code links to a D:ath-fin.jpg that I used as the default background picture, and the code is for 2 seperate forms.

I am an experienced programmer but mainly in 4GLs and assembly. Relatively new to VB programming, especially GUI applications. On a form I need to create an area that will be used to display *extremely* large TIFF images. typical image size would be 2000 pixels by 100,000 pixels. Typically I will NOT want to display the entire image at once, so the area will need to have scroll bars and/or other methods to scroll/pan around the image.
I have read about and tinkered with the bitmap and picturebox objects, including some threads about several different ways to implement scrollbars. However, I see that the picturebox size is limited to 32K pixels in both dimensions. I suppose that I might be able to copy various portions of the bitmap to the picturebox depending on scroll position, but that seems potentially quite slow and cumbersome. Can an expert developer who is experienced with these types of issues regarding the following:
1. Can bitmap objects be used effectively with TIFF images of the size I am working with?
2. an approach that should produce reasonable scrolling performance for these extremely large images without excessive coding effort?
3. For an image that exceeds the picturebox size when displayed at 1:1 scale, is the picturebox capable of displaying a reduced size version of such an image without lots of code, and if so, how?
4. Many (most?) graphics display objects count on all of their display data being stored in memory rather than on disk. Would that be true of a TIFF image loaded into a bitmap object and displayed via a picturebox? If so, the amount of RAM required in order to buffer the entire image in memory could be a potential problem for images of this size. Is there an advisable way to have the picturebox or other display object only load portions of the image into memory on an as needed basis, and purge them once they are no longer required? Are there any built in objects/methods/properties or is there any sample code to show how to do this?

Any code for creating the pallet for a Gray scale image, to display it on a picture box? I have written the code for creating for palette for a RGB image which is as follows:
Marshal.Copy(Image_bufffer, 0, _pImg, 1024 * 1024)
myBMP = New Bitmap(1024, 1024, 1024, System.Drawing.Imaging.PixelFormat.Format8bppIndexed, _pImg)
pal = myBMP.Palette
For i As Integer = 0 To pal.Entries.Length - 1
pal.Entries(i) = Color.FromArgb(255, i, i, i)
Next
myBMP.Palette = pal
Picturebox1.Image = myBMP 'Show the image
But the image displayed looks dull(less brightness) than the same image viewed from ImageJ. So instead of creating pallet from color.Argb, is there any way to create palette for a gray scale image?

Is there a way to tell the DISPLAY size of an image in a picture box? If the PictureBox.SizeMode=Zoom, the picture sometimes is not displayed as big as the picture box is, and is sometimes displayed smaller, or larger, than the actual image is. I just want to know what size it is actually displaying as.

I would like to know how to get a image/screenshot of a Windows Form in .NET while it is running as it would have been seen in the designer/when it is first opened, i.e. without any text in controls etc. Basically I would like an image of the form as it's clean copy.

Just like an array in a group box or a frame as i used in vb6.
If there are 5 customers details then when i load the form it will add (PictureBox, Label and a listbox) for each customer dynamically and display them with their information. Moreover, if i add 6th Customer information in the database then next time i load the form it should display his/her information as well. I did this in VB6 sometimes back but need a start to do in .net
Private Sub LoadCustomerInformation()
Dim Qry As String
Dim RS As New Recordset

I need to display 3 columns and a varying amount of rows (typically around 50) in a windows form, kinda like excel. The data will likely be longer than the window, so a scroll bar will have to come into play somewhere.

I've been working of a Visual Basic Windows Form in Visual Studio 2010 as my first little VB project. It's a form which runs a stored procedure on SQL. I have this all working, however, the stored procedure has a PRINT statement execute if a duplicate is found and stops. What I'd like to do is have this PRINT statement display on the Windows form MessageLabel (label) or have a "successful" message displayed if there is no SQL print statement.

I'd like to use a TreeView control to display database data in a windows form with VB2008. All the information what I found is related to a website design, but I'm working on a database program (sql2005), where I'd like the user to see the structure what he/she make up with a TreeView like control. Just something like that when you explore your hard disk. How can I do that?

Inside a form, I would like to display a pdf file which is already available in my resources (template file "untitled"). In this pdf file, I have some fields which get their values from some texboxes in another form. My aim is, when the user triggers the button to call this form, it should insert the values inside the pdf file and display the output pdf inside the form.I have written the code to an extend but could not finish it myself after my many trials... Now here are the two things I cannot manage:I can use a directory to read the template pdf "untitled1.pdf". But my aim is to use the file inside my resources. can save the output file in a directory but this is not I want to do. I want to display the output pdf.

I have a windows form where I want the time to constantly be updated. Right now it will take the current time from when the program was started.
For example, if I started the program at 4:30:29 PM that is what it will show the whole time the program runs.I need it to constantly be updated as the seconds tick by. So, If I started the program at 4:30:29 PM and ran it for exactly 5 minutes, the time displayed then should be 4:35:29 PM.The data being taken in and saved needs a time associated with it and the end user also need to know the current time as the program is ran in full-screen.

I have a procedure that loops through the directories/subdirectories on a file server and sets the permissions. Procedure is called on a button click of a form.
I need to display on the form which directory is being processed. Similar to if we use the Debug.writeline which writes to the output in Visual Studio. I tried using a ListBox but it only displays the last one and only displays the last one once processing is done. I want to be able to display each directory name as it is being processed.
Psuedo code as follows:
For each dir in L drive
setPermissions(dir)
'display in ListBox dir name
lstProgress.Items.Add(dir.Name)
Next
