I'm from Holland (The Netherlands) and new to this forum, I'm not 100% sure if I'm posting this thread in the correct subforum... I don't I have a little experience in Visual Basic .NET 2008 Currently I'm developing a program for my job in which you can follow a checklist for doing a certain procedure. With every step you have to click a checkbox and so on. It's saved in an XLS-file and blahblah, all irrelevant for my question.
I've got to the point that I'm almost pulling my hair here, because everything went fine so far with coding my program, but this simple thing I can't solve What I'm trying to do is, change the BackgroundImage of a Button when you click on it. If it is Image1 at the time of clicking it should change to Image2, and vice versa.
I been trying to create a section for my program to change the backgroundimage property of the main form. let me show the code: (some parts may be bad written but I was trying to try to find the problem) this code is a click event from a button
I'm having a strange problem with the OnClick event. In an ArcGIS application using VB.Net, I have a button set up with the following
AddItem("CommandAnalyseResults") The following module segment contains the OnClick event: Public NotInheritable Class CommandAnalyseResults Inherits BaseTool <more code...> Public Overrides Sub OnClick()
[Code]...
The OnClick event gets triggered no problem the first time I click on the button. However if I then close the window the button code creates and then click on the button again, the OnClick code is not triggered.
If I click on a different button then click back on the 'problem' button a 2nd time, it does seem to trigger the code!
I got a PictureBox Control with a BackgroundImage. Related to the active Image I will show the next image by manipulating the name-string. But how to get the name of the actual shown image? All my images stored under ressources.Following wont work:PB.BackgroundImage.ToString it will give: "System.Drawing.Bitmap"
Is it possible to set an IMAGE or BackgroundImage for a button from an online resource such as a [url].... file in any way at all . I would like to do something like this in a WINDOWS FORMs based application.>>
I need to alter the onclick to target different aspx pages based on what's read from the database. Something like:
If DBRead("Keywords").ToString.Contains("glove") Then Me.btnViewSpec.Attributes.Add("onclick", ("window.open('/SpecSheet/DisplayPDF.aspx?pa=/SpecSheet/GloveSpec.aspx?pid=" & intProductId & "','wnEmailInfo', 'menubar=no,width=820,height=500,toolbar=no,scrollbars=yes,status=yes')"))[code]....
Problem is I can't get the code behind to recognize the image. I tried to register it in the designer code with Protected WithEvents btnViewSpec As HtmlImage but no luck. I guess I just don't fully understand the issue or what gets registered in the designer code.
I have a question regarding VB.Net and Object-oriented programming.
I have a solution consisting of two projects.
One project is dedicated to the logic of the application, and one is only to show the Winforms form, and to reflect changes made in the logics project. In other words, when an array filled with various attributes residing in the logics project gets changed, then these changes should be reflected on the form (not that strange in theory).
Here comes the - for me - really tricky part:
I have created user controls, and these are residing in the forms project and placed on the aplication's form. When I click on any one of them, their respective onclick sub gets called okey, but how can I send a message to the logics project from their onclick subs? Basically, I'm not sure on what should be private or not, or possibly how to call the other project correctly. In any case, I can't get it to work.
To sum up: What I need is a line of code calling a class in another project, and someone telling me what should be private, static etc.
I am working with a .Net 1.1 web application. There is a Save button that, when clicked, will pop up the Javascript confirm box. Once the user clicks OK a long running process is kicked off. We would like to show a busy indicator when the user clicks the OK button of the confirm dialog.
I have a javascript function and need to add it to some dynamically created radio buttons onclick from code behind.I've tried newRadioSelect. Attributes. Add("onlick", "javascript:toggle(this);")The code above adds it to the span tag that the radio button creates, any ideas how to get it on the input tag of the radio buttons?
Main Form is my startup form and then 2 buttons on the form button 1 open form2 and main form hidden. button 2 closes and in the form 2 I have a textbox where I write some text and a button to save the text in a txt. File Once I've saved my text in txt. file so I click on a button that closes form2 and open main form My problem is that the button on the main form I should like to have button text is from the txt. file. And I do not know how I reload the button or form.
if I close the program and start it again, then my button text has change to what i write in txt file..
I have a button on a web page that I just need a little help with some extra code. I think I need a TRY, CATCH statement?, this is what I have so far: I have a simple web page that has a button which at the moment when pressed enables the user to add data to a DB table via a stored procedure.Once this button is pressed a pop up message box is displayed to let the user know the data has been passed. The user then needs to press the 'OK' button within this message box which then directs them to the home page of the site. This works fine.
The code for this is here:
Protected Sub btnAddRawData_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnAddRawData.Click 'database conn, this is linked to the web config file .AppSettings Using dbconnection As New SqlConnection(ConfigurationManager.AppSettings("dbconnection"))
[code]....
As I don't want the user to enter duplicate records in the database (This could be done by the user navigating back to the page where the btnAddRawData_Click is located and pressing it again.), I have created a UNIQUE INDEX named 'DupRecords' to stop the user from commiting this data more than once that day.When I run the web page now I get the following message in my browser:
Cannot insert duplicate key row in object 'dbo.GasRawData' with unique index 'DupRecords'.The statement has been terminated.The solution I think, is to add a TRY, CATCH statement into the btnAddRawData_Click code.
I'm creating an online exam page with 30 radiobuttons that are created dynamically at runtime. How will I get the click event of each radiobutton and tag it in my method that I will check if the next question is need to be jump or escape. Example: If I'm in question 10 and answer = "Yes", redirect me to Question 15, else go to the next question

I have a dropdownlist and a textbox with a button on a form. When a button is clicked it does not go to my onclick even in the code but it goes to my dropdownlist's selectedIndexchanged event. How can I fix this?
i want to know how to use vbscript to declare the function that handles the button onclick event or set a function that handles all button onlick event! both will do i.e) ihave a function
"sub xxx() end sub"
and i generate the buttons using vbscript. i can declare the button id, text without problem.
--dim obj as new button() obj.id="aaa" obj.text="ooo"
the above lines work just fine but when i write obj.onclick = "xxx", it doesn't work. by making settings on the function to handle all button onlick event is also acceptible for me!
I'm using VB.net '08 express and I have a form in a program with a picturebox. I have a series of images in My.Resources. What I am trying to do is get the images in the box to change in sequence whenever the button is clicked.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim sequence As Integer Select Case sequence Case 1
[code]....
When the button is clicked, the 1st image appears and the button then does nothing.
I'm working on a simple base form in which all the other forms in the project will inherit. This base form only adds 5 properties (at the moment) dealing with painting a gradient background. The problem I'm facing right now is when I change a property on Form1 (the test form) and click run it doesn't show that change. I also checked the .designer.vb file and when I make a change it's not added to the code behind file, I'm at a loss right now to why.
I was wondering if it is possible to change the size and button layout of a form by using a button. the only way i could make it appear to change size, was by having it so when you hit the button labeled "Change Layout", it would do
