Is it possible to search for images ONLY in WebBrowser? For example, my keyword in textbox1 is 'clouds' and when the button is clicked WebBrowser must show only images of that keyword.
View 3 RepliesSo I'm making a program that involves going online and entering a captcha, but the captcha doesn't show up. It just shows the outline of the image and then the name. How do I make it so the browser displays all images. I'd also like to know if there's a way to display the captcha in the main box.
View 2 Repliesam working with Web Browser control and with emails ".eml" ,simply am just navigating the WeBBrowser to the email object in my computer and is displaying my email body
but if the email has attachment picture(NOT AN EMBEDDED PICTURE) then the Browser automatically display that image to the center of the browser for example the last line of the html code is <CENTER><IMG SRC="CID:{A4BE96B0-6195-4D93- 45E-97D4B1CA3539}/nature2.jpg"></CENTER> but actually the email dose not has this picture as embedded but is only an attachment ,and the browser is displaying it.
is there any way which i can easily disable that functionality or i should modified the code and replace that string with nothing. ?
1. I have a program and I want it, when it's lunched it comes at the center (I done that already) now what I want is to lock it at the center and could not be move all around the screen.
2. The other thing is that in my program I have a Webbrowser and the images are not showing at all. To make the picture visible I have to right click the image and click SHOW IMAGE. Till yesterday the image was showing.
I want to show items in my gridview as a 5 across and a 5 down display - I already have the query pulling only 25 records per a page but cant seem to make the gridview do what I want

record 6 : record 7 : record 8 : record 9 : record 10
etc ...........................................
I want to create a form that shows different pictureboxes, showing different images, when the "Next" or "Previous" button is clicked.Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click 'button 1 is the "Next" button PictureBox2.Show()End Sub
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click 'button 2 is the "Previous" button PictureBox1.Show() End Sub
I have a thumbnail control where I am adding Images using openfiledialog and after adding it automatically scrolls down.
So I would like to stop scrolling the scrollbar and just append the Images.
I have tried using this code:
Thumbcontrol1.VerticalScroll.Value=0
It worked fine but the scrollbar is at the bottom and it shows me the first row of Images.
And this is my second attempt by doing this way:
I have just set the autoscroll property to false and it hides the scrollbars and I'm stuck with this so how do I scroll the remaining Images?
And Is there any other method to hide scrollbars and just scroll the Images using mouse? Or any other simpler way to get rid of this?
I have deployed my app no problem on my laptop that has .net3. I want to distribute my app to office xp nodes. This there a way of deploying an application to use .net2 instead of 3?
View 5 RepliesThis 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?
Display ajax loading image before loading anycontrol .... means if i wanna show textbox on button click after showing loading images using ajax toolkit or ajax extension in vb.net ?
View 1 RepliesI am having trouble. My string dictionary saves a controls.tag value then saves another value to that key(controls.tag)for example I store to my string dictionary like this:
vb.net
StringDictionary.Add(txtSAP_Phasing.Tag, "YES")
How can I match the values even if they are not the same case.my problem is im trying to match each controls.tag with the proper key in the dictionary.But the dictionary saves the string of the txtSAP_Phasing.Tag value as all lowercased, and the Tag value is actually all uppercase... and this is causing my IF THEN statement to not trigger when I try compare the two strings.

I need to retrieve my data from a ListView control set up in Details mode with 5 columns.
I tried using this code: MessageBox.Show(ManageList.SelectedItems(0).Text)
And it works, but only for the first selected item (item 0). If I try this:
MessageBox.Show(ManageList.SelectedItems(2).Text)
I get this error: InvalidArgument=Value of '2' is not valid for 'index'. Parameter name: index
I have no clue how I can fix this, any help?
Edit: Sorry, should have said, I'm using Windows.Forms :)
I have a ListView with 3 columns, how do I add specified text to the specified column I want? I've looked at the ..Add function, but it doesn't take the column index.
View 2 Replieshave 6 columns in my listview that should show the data from the database.. but when i coded it like this :
Public Sub showmyrecords()
Dim dt As New DataTable
Dim ds As New DataSet
[code].....
it shows the first row data(database) in the first column of my listview... how should i solve this problem?
what I am trying to do is, when a ListView loads, for the code to check the entry in column one, and then return a message box if the column contains a specific date.
I am using:
SUB I DONT KNOW THE METHOD TO INSERT THIS INTO. I NEED IT CHECKED WHEN THE LISTVIEW CHANGES
If lvuPreviousJobs.SelectedItems(0).SubItems(2).Text = "31/12/9999" Then
{
MsgBox("TEST")

I'm trying to put a listview on a VS 2010, vb.net winform form. I
1. drug the listview from the toolbox to the form.
2. right cick and did an edit columns
3. added two columns with the names of (chLocationID, chLocation) and the text of LocationID and Location.
4. when i click ok, nothing shows up in the listview designer.
In the code behind i did a for loop to add some data.
For Each O In oS
Dim itm As New ListViewItem
itm.SubItems.Add(O.tblLocationID.ToString)
itm.SubItems.Add(O.Location)
itm.Tag = O
lvLocation.Items.Add(itm)
Next
when i step through the code.. it says that it adds the row.. a lvLocation.items.count give me a value of 1.. which is correct but nothing displays on the screen.
For a university term project, I'm working on a graphical roguelike (I'm aware of the contradiction in terms :P) that uses an isometric display. What I'm trying to figure out is, since drawing all the tiles is stupidly expensive and unnecessary, I'm wanting to figure out a relatively fast algorithm to determine which tiles should be drawn to fit within an NxMpx window, given that the tile graphics are XxYpx.
I'm not doing smooth scrolling for this, so that's not an issue. I'm also not worried about being perfect - a little unnecessary draw is fine, I just don't want to draw a huge amount of unnecessary tiles that won't show up in-game.
I've been trying for a week now to get a clipped tile from a sheet and draw it in either it's destination picturebox or draw it to a picturebox that will be the same size and the clipped tile and then draw it from there to it's destination. Nothing seems to work for me. I even tried using Bitblt but that didn't go very far, although I had better luck with that then the built in graphics functions. So, for now, I removed all code and decided to start from scratch again.
The only thing I got so far is this:
Dim myImage As Bitmap = New Bitmap("C:UsersSomeClownDesktopBitblitTestinasis.bmp", True
picSource.Image = myImage
As you know, all this does is load a bitmap file into memory and the second line draws the bitmap to a picturebox.
While trying to find an answer to my question, I came across a project called OTSe, which allows people to make they're own online 2d online games. The system is based on an open X, Y, Z square tile map. For the sake of easy understanding, lets say they're are 3 types of tiles. Tiles you CANNOT walk on, tiles you CAN walk on, and tiles that SLOW YOU'RE CHARACTER DOWN.The project team has created a API class for users to work with in order to develop tools. What I'm trying to do, using they're classes, is GET the all the tiles on the current floor I am walking on, and then display them in a tile grid on my form, changing they're color depending on what type of tile they are. If the tile is NOT WALKABLE, make the tile gray, if the tile IS WALKABLE, make the tile brown, and if the tile SLOWS YOU DOWN, make the tile red. I also need it to store the information of each tile, since tiles are objects, and have properties.

If I enter a data in a textbox, I want my listview to select the same data entered in the textbox. Example: I have a StudentNumber column in my listview and it has data on it (ex. 123456)
I will enter 123456 in the textbox. The ListView must select 123456?
I have below code in my Form Load event handler but the ListView doesn't show any column headers. I want the column headers to be displayed.

I have created a project that uses a listview associated to an imagelist (LargeImagelist, I have set the size as 100 x 75 and 32 bit depth), that displays information from a database along with an image from the image list. My listview is set to tilemode so that I can control the size of the tiles to get two columns of six. The image list is populated when the form is loaded from all the images in a specific folder, this part is working appropriately as I can get a picturebox working consistently that references an image from the imagelist.

How do i add images to the first column of a listview in vb.net 2008..?
View 2 RepliesI've created a ListView called ListView1. In the first colum, I want to add either a stop sign or a grean light.
I create the columns
HTML
ListView1.Columns.Add("Item Column", -2, HorizontalAlignment.Left)
ListView1.Columns.Add("Column 2", -2, HorizontalAlignment.Left)
[code]....
This seems to generate alternating stop signs and green lights in the first column. Instead, I want to be able to decide which one goes on each row on the fly, as well as change them later.
I have a couple of images in a imagelist1. I'd like to display images in listview1 control. Once the image is selected it should display in a picturebox1. I should be able to navigate through (next/previous) pictures and I should also be able to delete pictures.
ImageList1.Images.Add(Image.FromFile(OpenFileDialog1.FileName)) not adding files!
I want to add images to listview and the code below should work in theory but it is not working. What should happen is when I select an Image from the openfiledialog it should then show in the listview box with the image plus it's filename underneath it. What happens is when I put 'Openfiledialog.showdialog' in the open button code underneath all the rest of the code and run my program.... it opens twice and only shows the file path but no image with it in the listview box. When I take that line out and press open..... it crashes and highlights any line with '(strFilename)' and says the error "not in legal form".
Here is the code for adding pictures to listview which is placed in the 'form_load' function
Dim Load_ID As Integer = img1.Images.Count
Dim i As Integer
For i = 0 To Load_ID - 1
'Add columns
ListView1.Columns.Add("I_Name", 100, HorizontalAlignment.Center)
[Code] .....
I am working on the listview that I have got two columns, the one that it goes for the images and the other one goes for the text data. I can extact the text data, but not for the images.
