I'm dynamically creating a button control, and I'd like to add a background image from my resources thing to the button.
Now, I'm pretty sure it would be:
CODE:
But I don't know how to refer to an image that is in my project resources.
I've tried:
CODE:
But that gives error:Value of type 'System.Drawing.Bitmap' cannot be converted to 'String'.
i am adding the button on runtime. how can i assign its background image? (no hard code for path) vb.net 2003
View 6 RepliesI am dynamically creating an unlimited number of background workers and would like to handle errors from them.
In a try statement I am using the following:
Catch ex As Exception
'Me.BeginInvoke(New UpdateTextCallback(AddressOf Error_Text), New Object() {Message, Account})
Exit Sub
End Try
I have commented out the BeginInvoke command because I can not get it to work. I get an error the the handle has not been created. This subroutine is in a module and I can not figure out how to get the invoke to work.
On my main form I have a 9 button grid that I need to fill with a gradient colour so that it represents a "heat map" going from Green (lower left) to Red (upper right). The "heat map" needs to be generated dynamically as - if I use an pregenerated image I have noticed colour variances when working on different screens / projectors as in the app there are other dynamically generated graphics & the two sets of colours need to match.So to achieve this - on my main form I have a PictureBox that I fill with the gradient colour.On top of the PictureBox I place my grid of 9 buttons.I then hide each button & take a screenshot of what is behind it & that then becomes the background image for the button. The button is then made visible.All works fine when I am testing in on a simple form The issue is that this arrangement needs to be placed on a tab control & I'm having difficulty replicating what I could do successfully on the simple form.....
Code for the colour gradient :-
Dim A As Integer
Dim B As Integer
Dim C As Integer
Dim D As Integer

I am dynamically creating and adding a ComboBox to a specified column in DGV. I also set a DataSource, DisplayMember and ValueMember for the created ComboBox. Somewhere else in my program, I select a number ( let's say 5 ) and based on that number I want to change the SelectedIndex of the current ComboBoxColumn ( I actually loop through the Columns collection ).I tried something like this in a event handler I created:
vb.net
Private Sub combobox_validated(ByVal sender As Object, ByVal e As System.EventArgs)
Dim combobox As System.Windows.Forms.ComboBox = sender
Dim colIndex As Integer = combobox.Tag
[code]....
You will notice here, that I'm not actually trying to change the .SelectedIndex property, but the Value of the current cell.How do I reference the actual ComboBox?
I am dynamically creating and adding dropdown controls to DevExpress XtraGrid.That works fine and I can add a dropdown control to any column I wish.My main problem is that I need to have the first element in the dropdown control displayed. But after I dynamically add 3 dropdown controls to the grid, only the last one has the element displayed. The previous two do not.Although, I add the elements
this is what the code looks like:
vb.net
Dim column as DevExpress.XtraGrid.RepositoryItem.GridLookupEdit
For i as Integer = 0 to dsSometing.Tables(0).Rows.Count - 1
column = New DevExpress.XtraGrid.RepositoryItem.GridLookUp
[code]....
The code will go tru and add lets say 3 dropdown controls, set their .DataSource to datasets I need, but it will only show .NullText of the last added control.
Is it possible to set Background image to a label at mouse enter event using fade effect also. I can set the background image but i also want to use fade effect. Ribbon Style effect will also do.

[Code]...
Here I am creating a new button and wanted to use it when pressed. I don't know how to do it, you can have a look at IF condition above.
what I am trying to accomplish worked with the code in the last thread I posted a while back. I still am using this code, however, I changed the window size to work better and gave it a nicer background for the title screen of my project. Now what I am working on at the moment is making a settings form that has 2 labels. One for "Default" Layout and one for "Plain" layout. When default is at start, the default label is disabled,and when plain layout is clicked, the button is disabled and default button is enabled.Basically, this is a toggle switch for default or plain where if one is enabled, the option for it is disabled and the other is enabled.My problem is that when I switch from Plain back to default, the background Image will not switch back from the plain background color of "control"Here is my code:
Public Class Settings
Private Sub LinkLabel1_LinkClicked(ByVal sender As System.Object, ByVal e As System.Windows.Forms.LinkLabelLinkClickedEventArgs) Handles LinkLabel1.LinkClicked

Then I built the test control and tried to added it to the Toolbox. When I did this--i.e., browsed to the dll and double-clicked it, I got the errror message:
"There are no components in ... that can be placed in the toolbox."
Is it even possible to add a User Control to the Toolbox without compile-time components?

View 1 RepliesI have already posted this question on the "reporting services" forum and received no responses, so i thought i'd give it a try here.
SQL server 2005 SP3, VS 2005, vb.net, RV control.
When i add a background image to the page header, body and page footer, The rendering takes about one second per page. Without the background images, it renders about 25-50 pages per second. My report is a statement print report and has about 1500 pages.
Since it is the same image on each page, why does the server need to send that image over and over again to the report viewer control?
In vb.net i have the Report Viewer control and i bring up a report in normal viewing mode. when i click on the print layout mode, or have that mode set up to be the default mode, It takes forever when i have a background image and virtually no time for the same report without the images. The images are gifs about 5 or 6k each. I have chosen to embed the image into the report.
How do i optimize the usage of background images so they do not interfere with the rendering speed? Or at least minimalize the slowdown.
[EDIT:] I have discovered that if i render it to PDF and open the PDF and page through the report, it is much much faster. In other words if i choose to render to 'printlayout', it is say 25 times slower than when i render it to default, and about 20 times slower then if i render it to PDF. And the PDF contains exact rendering for all pages, exactly the same rendering as the print layout mode generates.
I have created a custom control that has a few labels and a button on it. In my main program i dyanmically add this control to a stackpanel. When i add the control i add a few events for it by doing th e following:

How would i go about adding an event for the button.click for the button in the custom control?

View 2 RepliesIn my project, I have a form with a background pic that I like, but unfortunately, I also have a ListView on that form which covers most of the picture. Now, is there a way to find the part of the background image concealed by the ListView, and then display it as a background image of the ListView at decreased opacity? You know, like a vague image.Just one more thing, setting the form's transparency key to the background color of the ListView is not an option.
View 39 RepliesI have used this form to add new records on my database(ms access) in my database I have a column name 'ID' which is my primary key 'ID' is set as auto number. Now I am having a trouble on creating my update and delete button it's always saying "cannot be delete/update"
Here's my code on add, update and delete
Public Sub SaveRecord()
Try
Dim dbConn As OleDbConnection
Dim dbInsert As New OleDbCommand
Dim str1, str2, str3, str4, str5, str6, str7, str8, str9 As String
[Code] .....
Note my add is working perfectly fine. I just can find the error on my delete and update. Also I have used this to view it to my datagrid I don't know if its the right thing but it's working fine too.
'declared dbpath globally'
Dim dbPath As String = "Provider=Microsoft.Jet.Oledb.4.0; Data Source=../VG.mdb;Persist Security Info=False"

Another thing is how to code each textbox and combobox to bind it to my records so that when I click on the datagridview each column will be distributed on each respective textbox.
