I am using Visual Basic 2010 for a project.My project requires to place a TRANSPARENT button on top of an image (placed inside a picturebox). for that to work, i need to set the button's parent to the picturebox. Is there a way to do that in design time? I cannot find anything on the property tab. The reason i want to set it on design time is because my project will have a motherload of buttons and it will a pain to code the parent change....
View 3 RepliesIn some of the forms ,whenever i change some properties using the Properties Window of some controls or the form they get reflected in the Properties Window but will not get changed at Run Time.
I am facing this in quite many of the forms, hence i am applying the property changes in form load, this is causing performance breach .
In a VB.NET winform App I want to place icons on each tab header of a TabControl.I set the ImageList property of the TabControl and for each Tab I set the ImageKey property.My icons show as expected on each tab at design time within the IDE but when I run the App, my icons don't show (an empty space is shown instead).
View 1 RepliesI have a small dataset which has most of its schema defined at design time, but I add a few columns to one of its tables at runtime. My problem is how do I reset those changes? he dataset is not linked to any datasource. It just has its own table which I "manually" populate. The static columns have been added to the datatable at design time. However, I add a few columns as runtime based on a list of categories. Like this:
[Code]....
The dataset is used in a small dialog that pops up within my application. I add the dynamic columns when the dialog is opened by using the Load event. Everything works great the first time. But if you close the dialog and reopen it, there are problems. My startup routine tries adding the dynamic columns again, but an error is thrown saying the column already exists. I have tried a lot of things and did some reading but I can't figure out a way to reset the dataset when the dialog is closed. The only solution is to close the whole application and reopen it. I have tried the following in the Leave event of the dialog form:
[Code]....
I use try catch finally to handle errors in my program. And these work fine when i debug application, but when i install it, error handling does not work?!

View 2 RepliesI've created an SQL Query using the query builder. In the query builder, you can test the query by clicking the button "Execute Query", and entering the desired values in the parameter fields.
My query returns the correct results when I do this, but when I seemingly pass the same values at runtime, I get 0 records returned.The query is designed such that you can pass nulls if you don't wish to filter data by that particular parameter.
SQL Query:
SELECT ID, UPC, Quantity, Manufacturer, Style, Color, Size, Category, DateReceived, Cost, OriginalRetail, Retail, LocationID
FROM Inventory
WHERE (UPC = @UPC OR
[code]....
In the query builder "Execute Query" dialog, I enter a value I know that the db contains in the "Size" field, "1/1/1900" & "1/1/2199" in Dates A & B, respectively, and nulls for all other fields. This returns 1 record, which is just as I expected. It works correctly.But when I pass the same values into the method created by the designer, I get 0 records returned. I can't figure out where the problem lies. Even if I enter nulls for all fields other than the dates, it returns 0. This tells me that the dates are causing the problem, but I can't figure out why, because I'm passing strings equivalent to what I entered in the query builder.

View 11 RepliesI am creating a custom Label control (by simply Inheriting the standard Label control and re-painting the background and text) because I need a very specific background and border. In the constructor of the control, I set the AutoSize property to false so I can have a standard default size for the new label.
Public Sub New()
/*Set the default size of the control to 75x24*/
Me.Height = 24
[code]....
In my application that uses this control, if I create the new custom label at run time (in code), the AutoSize property stays False, and it works properly.If I try to add the new custom label to my form at design time, it comes in with the AutoSize property set to True, and I have to manually set it to False in the properties window. It's not a huge problem, but I don't understand why the behavior is different.
New to reports here. Using VB.NET, my application makes use of datatables it creates from a postgresql database.These datatables are defined at runtime rather than design-time, and I would like some way of generating reports from these datatables at runtime as well.
Should I be trying to create the report template at design-time, and then "binding" a datatable to it at runtime?
i have a treeview which has a bunch of parent and child nodes preset at design time, there is 1 parent node tho which is called developer, that i want to add child nodes to at runtime.When the form first loads im trying to have it check a text file and for each line in the text file add the text/string from that as a child node tot he 'developer' parent node.
vb
Dim reader As String = My.Computer.FileSystem.ReadAllText(Application.StartupPath() & "ConfigDevs.txt")
Dim strs() As String = Split(reader, Environment.NewLine)
For Each s As String In strs
[code]....
Thats what i have so far, how can i set it so 'Dim parentNode As TreeNode = ' points at the 'Developer' node?
I have a splash screen for my program that I want to have a background image that changes each time the program opens.One way I saw to do this is to load it from a ImageList, but that has an maximum image size of 256x256.The splash screen is 498 x 305, which means that I need to find something besides ImageList but hopefully with a similar ability to organize the images.I did try just putting them into resources, but wasn't able to get it to set the background without erroring, and I'd prefer not to have 30 images cluttering the place up.
View 1 RepliesI've got a VB.Net form application that dynamically loads user controls based on which navigation link the user clicks on. I'd like to make it easier to use at Design time by putting a link of some sort to open the User Control at design time. The link would go onto the form in the space where the User Control will be going. This just saves a little time from having to browse through the files to open the correct file.
View 2 Repliesusing VS2008, targetting framework 3.5I have a rather complex UserConrol which does some of its own rendering.I display this UserControl on a form.Opening that form in the Designer creates an instance of the UserControl in the Designer, which tells me a NullReferenceException is occurring in one of my rendering methods.I have attempted to correct this by making alterations to the UserControl's default constructor, but have not found success.
View 1 RepliesJust started with VS2010. (vb)
Coming from VS2005. (i skipped VS2008)
My question is this. Why do I have to hit save before every build in order to see design changes at runtime? Example: I change the text on a button at design time. I click on run and the text does not reflect the change. But if I saved the form before clicking run, than it does. Also like to add VS2010 runs much slower compared to VS2005 running on the same computer. I understand VS2010 can do more, but a lot of times you don't need it to.
Converted an VS 2003 VB Application to Visual Studio 2010. Conversion seemed to work great. Having trouble with the Backcolor of buttons. In design mode they are a light gray (I have them set to transperent and they are on a VBPowerPack.Blend Panel) - but in Runtime they turn the correct color (Steel Blue). How do I get design time to look the same as runtime? Also, they stay light grey in run time if I check Enable XP Styles. Makes me feel better to see the same colors at Design time
View 1 RepliesI have a question regarding the manipulation of a form at runtime. Let's say I created a simple form in the form designer before runtime containing a couple of buttons, text boxes and labels. While the program is running, I would like to change properties of these controls, while having the ability to move them around, along with the addition of newer controls, say a listbox.
After the form is 're-designed', I would like to save the new settings of my form, in either a database or settings file. Whats the best way to implement this?

I can put how many new fields and labels with som "hello" text that I wont but they are not displayed at runtime. But all database changes the report i connected to will be displayed.
How can that be? What is wrong with my report when all datachanges runs thru but not my design changes?

I'm looking for a more elegant way to work around a problem I have
Code:
Private Sub MnuCheckForUpdates_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MnuCheckForUpdates.Click
Dim startInfo As New ProcessStartInfo(mStartUpPath & "" & "Updater.exe")
Process.Start(startInfo)
End Sub
As you can see I�m calling my updater program, but I want some code to run only after the Updater has closed.My work around was to:
A - Initially load the updater.
B � Start a time
C � Check if the updater is still running.
D � If its not call the routine in the timer event.
But this is not elegant is there another way around this, I can call events in the updater but I don�t think I can join them in someway to ProcessStartInfo Class .
I have made a program that has an intro screen, moving onto an activity select screen which acts as the main interface to get around the program. After creating the program and installing it on my computer, when I close the program from the activity select screen, using the "X" at the top right corner, the program continues to run under "processes" in the task manager.If I close the program from the intro screen though, it will close everything, including the processes. Is there anyway I can get the same to happen with the game select screen? I can make it work by putting my own "End" button on the form, but id prefer to be able to do it with forms own close button.
View 5 RepliesI'm working on program that has two forms. The main form is called 'frmMain'. Second form is called 'FrmHistory'. In the History form, you can check a number of combo boxes to set settings for a grid.
This works.Now, when I close the FrmHistory form and then open it again, I have it so those combo boxes (Settings) are how I left them. This works. I do so via this.
