Now i want to do some grafic effects on the form.How can i put an image(such as Logo ) in a picture box on form. I tried to load the image of type JPEG and when i load it in the picture box it does not fit into the picture box it is too large to fit in the picture box.Also i want to display this Logo as background image on the whole form.
View 17 RepliesI hoping to find a current and simple way to do this. I'm using VWD Express 2008 and SQL Express 2008.I'm able to get the client's path to the image file using an asp:FileUpload control on the web form.
How do I upload the client's image file and display it in the web form's image control?How do I save it to the sqlserver? The image table is already set up with a "Image" data type column. Can the image be saved to the database as simply as other data types?

View 3 RepliesSo 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?
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:

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?

View 1 RepliesI have a problem in timers, I want to display 2 forms each one after 3 and 5, how to do that? I mean when the first form appears, after 3 seconds another one will appear, then after 5 seconds the second will appear.

tmrnote.Start()
Private Sub tmrnote_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles tmrnote.Tick[code]....
I still have problem when the message box stops, it displays all the forms together. All I want is when the message box stops, then it display the first form then stop to display the second then stop to display the last. The first form must stay for 3 seconds on the screen, then after 3 seconds the second appears then after 5 seconds the last appears.

I can't remember exactly if this is possible or not but what I am attempting I would think should theoretically be possible. I know it is possible in WPF but the company I am working for doesn't want to make the transition just yet. Basically what I want is to use a background image on a form for the background and I have a docked control on the right and left. I have set the background on both of these docked controls to transparent however it is showing the back color rather than the background image. I tried, rather than setting the background image property, to override the onpaintbackground and onpaint events and use e.graphics.draw(picture, me.clientrectangle) but it still seems to just pick up the backcolor as the true transparent background so I'm wondering if it's possible to get it to show the background image through the control rather than the backcolor of the form?

In this program you should read text from a file one character at a time instead of one line at a time. If <tt>sr</tt> is an IO.StreamReader, then <tt>sr.Read()</tt> will return an integer that is the value of the next character in the file. Use <tt>Read</tt> instead of <tt>ReadLine</tt> in this program.You can check whether a file exists by using the code <tt>IO.File.Exists(filename )</tt> . The function will return a Boolean value (True if the file exists but False if not).
You can check whether a string ends with a specified pattern by using the <tt>EndsWidth(pattern )</tt> function. For example, if <tt>s</tt> is a String, then <tt>s.EndsWidth(".txt")</tt> will return a Boolean value (True if <tt>s</tt> ends with the pattern but False otherwise).In a string, <tt>IndexOf(pattern )</tt> gives the first position where the pattern exists, but <tt>LastIndexOf</tt> gives the very last position where the pattern exists.The code <tt>s = Chr(i)</tt> converts the Integer <tt>i</tt> into a character and assigns the character to the string <tt>s</tt> .
