I am using Visual Basic 2005. The program I am creating can either bring up a form (with a bunch of buttons, listboxes and a picturebox) and the user can enter file names onto the form OR the user can drag file names from Windows Explorer and drop the names on the program icon to start the program. During the execution of the program, messages are displayed in one of the listboxes.
All this works fine except for part of the drag/drop scenario. When the drag/drop is done, the form is not fully loaded when the code function starts to put out messages. This means the user may not see any of the messages until all is complete. I have tried putting my executable code in the Form1_Shown() and even added a timer to slow things down a little, but nothing seems to work consistently.
I'm trying to login to a website wait for the page to finish loading then navigate to a page in this website.
Here is what I came up so far
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
WebBrowser1.Document.GetElementById("nickname").SetAttribute("value", "user")H

How to use the documentcompleted?
I need to get the url of the webpage the webbrowser is navigating to, but since the code executes faster than the webbrowser navigates to the webpage, it gets the url of the last page. I cant use DocumentComplete Event because i have a tabbed browser,
and i cant write events because im creating tabs(with webbrowsers) at run-time. So how would i check to see if the webbrowser has loaded a document?
Is there a way of stopping the main page waiting for a usercontrol to load before it can finish loading?
I have a usercontrolthat has to do a lot of DB calls which can take a few seconds making the page slow to load. Ideally I'd like the main page to load straight away and then the usercontrol content appear when it is ready.
I have been tasked to do a project, and have been given a list of links from the client - what the Project needs to do is:1 - open google with a specific search phrase - no problem2 - look on that page for any links containing any member of the list of links, if found, invalidate the entry in the list, and auto-click the link, then go back3 - repeat for any other "finds" on that page4 - when done, auto-click on "Next" (no problem) and go back to step 2For now, I am not even attempting to auto-click the found link and go back, I am just listing all found links in a TextBox. The problem I am having is waiting for the next pages to load before looking for a match in the list of links. I tried using webBrowser.DocumentCompletedto set a Boolean - I tried testing WebBrowserReadyState in the DocumentCompleted event ar the code below gives the best results but it is inconsistent, meaning it completely misses some pages that I know have links on them that match.

View 5 RepliesI am needing to cancel a picturebox from loading. However, I need to cancel is from loading using the imagelocation command.
Example.

Is it possible to load an *.ico file onto a PictureBox ? I know I can use : PictureBox1.Image = System.Drawing.Image.FromFile("C:MyImage.jpg") but I'd like to use an icon . I have tried some other methods that read "Icon" , but I failed . Up to now the only thing I have thought is converting the file format form *.ico to *.jpg , but I think that's ridiculous ...

View 1 Repliesi know this is probally a really simple question but i have looked through my book and all my notes and googeled and couldn't find a answer that suites my needs.baisicly i have a combobox that gets loaded on form_load, what i want to do is load the appropriate picture into a picturebox when someone selects a item from the combobox. what i cant figure out is how to get the picture into the combobox using code. all the images are saved in my debug folder for the program. picturebox.image = picture.png this is what i asumed it would be but have tried with parenthises, quotes and both and it dosent work.
View 7 RepliesI'm new in the vb.net world. The question I have is how to display an image which is in a access data base in a picturebox in visual basic(2010).
View 7 RepliesI want to make a program similar to this one: [URL]. I already have the ListBox ready. But how do I load the images?
The image name works like this:
-File1.package
-File1A.jpg
-File1B.jpg
So the .package is removed and A.jpg or B.jpg is added.
I am trying to get a picture box (that has a loading image .gif) to be visible while the program reads a text file and change visible to false when all the information in the file.txt is displayed in the textbox.
Here is my
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
PictureBox1.Visible = True
If System.IO.File.Exists("C: est.txt") = True Then
Dim objreader As New System.IO.StreamReader("C: est.txt")

I have on a simple VB form:Label1Picturebox1FilesysytemwatcherThe watcher watches the camera but only the first picture load after that it gets an exeption and the program stops. I like to continu see what I shoot, but don't want to push buttons on the laptop after each shot. That reason the the watcher is placed. The time between shoot is enough for thw display being completed. The code:
Private MyImage As Bitmap
Private Sub FileSystemWatcher1_Created(ByVal sender As System.Object, ByVal e As System.IO.FileSystemEventArgs) Handles FileSystemWatcher1.Created

I currently have 4 images that I need to load into a picture box at different times, it works fine for me but if I send it to a friend it wont work because the file path is different. I use this at the moment:
If filmType = "Jumper" Then
img = "E:TheatreBookinginimages"
picFilms.Load(img)
lblFilmInfo.Text = ("A genetic anomaly allows a young man to teleport himself anywhere.")
lblFilmInfoTwo.Text = ("This gift leads him into a war that has existed for centuries.")
End If
I have a picture box on my form along with a combo box with a number of different options. So anyway when a combo box item is selected I want it to look in the dataset for the selected item's row and pick out the image to load and then using an IF statement it sets the image (or should).
Dim RaceImg As String = DS.Tables("tblRaces").Rows(ID).Item("RaceImg")
If RaceImg = "AusGP" Then
GP_Picture.Image = Image.FromFile("./Track Images/AusGP.png")
ElseIf RaceImg = "MalGP" Then
GP_Picture.Image = Image.FromFile("./Track Images/MalGP.png")
End If
I have tried a number of different ways to get this working, I have tried them in the resources for the program and also tried the following code
GP_Picture.Image = "./Track Images/AusGP.png"
It seems like the picture box isn't redrawing or something? Just to add it will load the first image which is the AusGP because thats the first option in the combo box, after that none of the others will load.
I'm sure there are similar threads, but I've search and tried most things and still can't find something that works.
I am testing a small project, in the attempt to find the solution for a much bigger application. So, here's the deal. I'm using VB 2005 and MSSQL 2005 (both are Express editions). I've stored the names to some images in the database.
When I use PictureBox1.image = My.Resources.<filename>
and build the application, it works and properly displays the image. Now, what I'm really trying to do is extract an image names from the database and assign it to a variable, this is what I have.
Dim EqTest As New Test1DataSet.EqTestDataTable
Dim EqTestAdapter As New Test1DataSetTableAdapters.EqTestTableAdapter
EqTestAdapter.Fill(EqTest)
[Code]....
I've used the messagebox for testing so that I can see what the value of "Trythis" is, and the string is "My.Resources.<filename>", which is the correct string, but I can't use that string in the picturebox to display the image, because I get an error "Value of Type String can not be converted to System.Drawing.Image".
I want to load images into a picturebox, save them into a database and display them again in the picturebox. This is the code I'm actually having problem with:
Private Connection As String = _
"Provider=Microsoft.Jet.OLEDB.4.0;" & _
"Data Source=C:UsersclientDocumentsVisual Studio 2008ProjectsSavingsLoansCalc.mdb"
rivate Sub UploadButton_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles UploadButton.Click
[Code] .....
I'm getting this error message:
"Type 'Connection' is not declared"
On this line:
oConn = New OleDb.OleDbConnection( _
New Connection().getConnectionString)
Just want to know the best method to load a picture in a picture box dynamically. As part of my development, I was supposed to load 4 pictures from network to 4 picturebox controls.
For which, I found, 2 methods.
1. Picturebox1.Image=new bitmap("C:\test.jpg")
(or)
2. Piturebox1.ImageLocation="C:\test.jpg"
Which one is more suitable interms of performance.
I have a 4 pictureboxes for a database I made but having a problem with loading images in to the picturebox. On my form I have a picturebox, 1 button, 1 textbox, and 1 openfiledialog.
My button click event code
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
OpenFileDialog1.ShowDialog()
TextBox1.Text = OpenFileDialog1.FileName
Pic1PictureBox.Image = Image.FromFile(TextBox1.Text)
End Sub
I can add pics but if I don't select any image (just close the dialogbox) I get an error and not sure what to do ..or what to add. Is there any code to tell it to just close..
I am trying to 1) write code in VB2010 that will get a JPG image from a Access Database field and write the image to a PictureBox 2) write code which will write a JPG file to an Access Database field. I have already sucessfully coded this in VB6, without fully understanding what I was doing.
Browsing the various forum's I have come across a few discussions on this subject, but due to my complete amerture status I don't seem to be able to follow the logic.

View 17 RepliesDoes anyone know how to finish this code by using only do until, do while, and if then statements? Also, does anyone know how to have the combobox display only 1-4 and not repeat as well?
The objective is to be able to select numbers 1-4, hit result, and have the label display female voters in that precinct out of total voters.

I am trying to make a marquee progress bar run while my long function is running. When the function is done running, I want the progress bar to disappear.
[code]...
If I don't do t.Join(), the progress bar disappears right away and then the thread runs. If I do Join(), the progress bar doesn't appear until the message box pops up after the thread is done!How would I get the effect of the progress bar running while the thread is running and then stopping when it's done?
