I want to populate an imagebox in my VB .NET form. The issue that I am having is that I am trying to write code to select all from a Visio page and copy the selection, then Paste Special the copied selection as a Device Independent Bitmap into my imagebox in my form at runtime automatically.

I have Picture in the same folder that stored my vb project. the folder name is Pics. and on the form I have ImageBox and CommandButton. What i want is when I click the Button I need to get the image inside imagbox.
example: image1 = PicsMyimage.jpb
Well my problem is so far the favicon shows up. But some sites don't have one and what i want is for a picture box to become visible when that happens.But i can't get the code to work (i suck at coding no surprise there).[code]Problem is it doesnt work. What happens on sites that dont have a favicon is that the last favicon loaded is the favicon of that site without a favicon.
View 3 RepliesAlright, so I'm still working on my slot machine, and I have it all done, for the most part, just got a quick question. I don't know how to set an image in an imagebox. Here is my lame attempt. I've been pulling my hair out and searching google for about an hour now
[Code]...
After a long while I started a project in VB.Net. I am making a security cam application for my own room. What I have done so far is capturing image from webcam (15 fps) to a imagebox and copying a still image from that imagebox to another in an intervall I have decided. Afterwards my code saves the image with a date and time as jpg. The code for capturing image I have found in this forum (iCam). My problem is (by the way I am an amateur programmer ) that the first imagebox (for realtime image capture) is not being showed (I dont want to see it). But if it is not active then all still images (saved as jpg) are all black. I think it is a drawing issue. I think imagebox is not being drawn (because it is not visible (actually the form is not visible)) and that is why still images are black. But I really don't know how to fix it? The class for capturing still images is very useful but only works with an imagebox.
(I really tried to understand the code. Especially the function, which copies a still image from 15 fps webcam output to a imagebox (which is used to save image as jpg file). But there are objects like: IntPtr, Hdc (getHdc, releaseHdc) and BitBlt. I really don't know anything about those objects.)
Code of iCam:
Option Explicit On
Option Strict On
Public Class iCam
#Region "Api/constants"
[CODE]...
I get realtime images with: iCam.initcam(me.picturebox1.handle.int32) and copy with: picturebox2.image= iCam.copyimage(picturebox1,New RectangleF(0, 0, Me.picturebox1.Width, Me.picturebox1.Height))
I want to know how i can create an imagebox using code, and is it possible to change the position of it later on in the script?
View 8 RepliesI have a list of images (paths) and when I click one the image is shown in a picturebox which is located in a panel which I can resize at runtime. The location of the picturebox = 0;0 and sizemode = autosize, because I don't know what size the images are.How do I make it so that the (small) images are always shown in the center of the panel?

The program has an MDI parent and its child forms. When opening one of the child form, the program seems to be working fine (it populates data from mysql and presents it to corresponding textbox, list and other controls). When you click Edit and save the data, the data is successfully saved and updated. But when you close the particular child form (without closing the MDI) and reopen it again, it cannot populate the controls (textboxes, etc.) with data.
I can do this easily with table adapter, but I can't seem to use variables in the table adapters connection string, or specify the connection string to use before "filling". Is there a way to populate the form without using any sort of binding? Currently I've used this method - a search form that populates a list box, and on the double click action I have this:
Private Sub lstResults_CellMouseDoubleClick(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellMouseEventArgs) Handles lstResults.CellMouseDoubleClick
'Fills Main Form
Dim firstcellvalue As String = lstResults.Rows(e.RowIndex).Cells(0).Value.ToString()
frm_IMT.intPendingID = CInt(lstResults.Rows(e.RowIndex).Cells(0).Value.ToString())
frm_IMT.Show()
Then When the form loads:
Me.PendingTableAdapter.Fill(Me.Phone_memo_backendDataSet.Tables("Pending"), intPendingID)
I am trying to populate a form from a list of values. I am fetching data into a recordset. I have a textbox that displays the date, however, when I try to assign a date value I am getting the error message that I cannot set the textbox value to a textfield. Is there a way to assign the date value to the textbox?
lForm.txtFromDate = dgvRequests.CurrentRow.Cells("leaveStart").Value
is what I have so far. I have a form that needs to load a file externally and populate the combobox. I can get that part if I use a button, but I don't want to use a button. I want it to populate when the form loads for the first time. The below code does not accomplish this, it doesn't even try to load it. I put break points in this code but it never breaks
Private Sub mortCalMain_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

I am building a program where for part of it the user can enter a parameter which will then query a database and populate a DataTable with the results if the number of results is greater than 1 it will call a "lookup" form to popuate a DataGridView with the DataTable, from this the user can select a row and the result is passed back to the main form or if the result is not there the "lookup" can be closed.
This works fine the first time the parameter is used to query and opens the "lookup" form and populates the DGV, but if the user returns the the main program after using the lookup form and enters a new parameter and the lookup form opens again the DataGridView is not created and populated. But i am 99% sure the DateTable is being populated as if the row count is 1 it will automatically return the single value and this is happening even after the lookup form has been used.
So it is just when the Lookup form is being used a second time the DataGridView is not being popuated or the DataTable is not being passed.

I have a system that I need to connect to an access database. Once connected, I have a form that allows a new customer to be entered into text boxes. I need to then take the data in the text boxes and save them in the database table.On a similar note, I have another form, where the customer details can be updated. Basically, by searching for a Customer reference number in the database, the form is populated with the table data. Then I want a button that will update/overwrite any chages made.

I want to display (DataGridView's) selected row contents (each cell value on appropriate text box) on text boxes on the form. This should be fairly simple task for experienced i am sure.So far i haven't been able to find a single working solution to accomplish that as most of the articles are written for VB / VB 2005/ VB 2008 and not VB 2010.
Here is what i have already tried. (I tried putting an image but i can't due to my privileges over flow) TextBox1.Text =DoctorsDataGridView.CurrentRow.Cells(0).Value.ToString It strangely works for first 4 selected rows and populate text boxes but fails for the rest of the DataGridView.
