I'm developing with VB.NET 2008.One of my host was crashed, so I take the files and keep development on another host. But now something strange is happening:All frames, lines and shapes are disappeared on design-time, but are seen normally in runtime.

i have a splitter control on tab 2, a grid and a scheduler control on tab 3..looks fine...i save it....close the form...reopen the form, and the controls are all resized and moved around on me....and not for the better.
wierd thing is that when i run the app, the controls are placed properly, but design time is totally f&*ked up.I know this one isn't me. is it the tab control? should i just do toggle buttons at the top and show/hide my own panels? this is just too freaky to deal with. is there an easy work around for this?
I have a VB 2008 program that has a number of forms. When I run the compiled program on a different computer, the form appears different. The relative position of various controls on the form are different. Its as if the controls have been repositioned. Resizing the form does not correct the problem. The only difference between the two machines is the size and resolution of the screens.
View 4 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.

How do I test for design time? The following code works during RunTime but fails in Design Time?
I assume it is because there isn't a Me.Parent.Name at design time.
Dim strGetColors As String()
strGetColors = fncGetColors(Me.ParentForm.Name)

I want to have a bunch of different screens, yet I don't want to have to use 20 different forms (I'm pretty sure that's bad practice anyways), and I don't want to lay down all the controls at once in the designer because then things get messy. I had an idea of running a sub on startup that would dynamically generate all the controls I need with all the right coordinates and settings, and then dump al the ones needed for a specific screen into a Panel. Then I return an ArrayList of panels, and pull out the correct panel to attach to the form when I need that screen. The only problem is that my form will not have any implicit knowledge of its controls, so I'm assuming I wouldn't be able to use the WithEvents / Handles. keywords to declare handlers in the form class (which is what I'd rather do).
View 3 RepliesI want to bind Grdiview with DB.I have a table Products with three columns.Suppose I add three columns at design time in gridview, If I run my following code First Three columns are blank & next three columns are bind with data.
Suppose I do not add any column in GridView & runs the foll. code,then the output is coming correct.
But i want that I add columns at design time

OK i have a combobox on the form. I have entered 4 values. I have left the TEXT field blank.Is there any way i can set the default SELECTEDINDEX of the combobox in the form design window. I know how to do it using code. If i set the TEXT field to one of the item values will it automatically select the corresponding INDEX
View 1 RepliesI created the dataset and connection to my SQL database at design time to make it easy to drag and drop bound controls and stuff to my form. My problem is this, when I did this it creates the connection string in design time also, but the connection varies depending on where the software is installed after the development.My question, is there anyway to set up the bound controls on my forms and everything with the typed dataset created in design time on the connection created in design time... then when the application is run, can it change the connection string at run time to get it connecting to and creating the dataset from the the correct sql database?
View 1 RepliesI have a problem. I have created a control, Now whenever I am going to Drug that control on my form then a error popup will appear that says "Failed to create component 'XXXXXXXXX'." System.IO.FileLoadException: A strongly named assembly required. HRESULT: 0x80131044 Is there any facility available in .NET for design time debugging Means If I drug a control on form then I will allow me to debug the control.
View 1 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 .

I'm making a quite large database management program(well actually 3 databases) and I am going to be creating a tab page for each database and under that a tab page for each table. each database has +- 200 tables and each of those has between 10 and 50 columns. I am also gonna put controls on each tab page of a table that represent a a row of data.I need very specific tooltips, functions for each table so generating it would be to complicated for me.
I need a automated way of creating controls on design time depending on the column datatype like a rich edit, text box or numeric up or down. and a label that has the same text as the column name It should also rename the name of the control to something appropriate .This can be done using visual studio's database wizard, but last time when I was about 30% done with one database it had already auto generated more than 1000000 lines of code. When I ran my program it took 10 minutes to show the first form and I have a powerful pc.
I vaguely remember something about a hotkey or menu that would group controls together at design time so you could drag 2 or more controls around and they would remain relative to eachother. You could work on something else and come back and the controls would still be grouped.
Does anybody know what this feature is called and how I can access it?
Basically, in the designer I want to be able to connect a collection of objects to another property. When the collection is set, the property should display a drop-down allowing you to select one of the values from the collection. It is a collection of a custom class.Right now I have the collection implementing the IList interface from the System.ComponentModel.Generic namespace. I've looked into type converters, but I haven't been able to figure out yet how to get them to work for my needs.
View 3 RepliesI've developed a derived form class that contains various collections of data. Corresponding to this data, I have a series of custom controls which can be linked to said data. I do this via custom UITypeEditors that convert the Custom Controls' Form into my derived Form Class Type and filling in a ListBox with the relevant data for the control in question. When the controls are serialized by the designer, it only stores the index value.
The above all works fine. However, I have found 1 bug that I am trying to work out - which is that, during Design Time, Custom Controls that are placed in sub containers (like a Tab Control) will fire their Load Event BEFORE they are placed inside of the Form. Is there a way to prevent this from happening? OR is there an event which occurs when the Controls are truly placed inside of a form (and not merely a sub container)?
EDIT: Upon Further Inspection, this problem only occurs with the Tab Control and not with other sub containers like Group Boxes, Split Panes, etc.
When trying to edit an exisiting or trying to create a new dialog with a MSFlexGrid I get the following error
The ActiveX control "Microsoft FlexGrid Control, version 6.0" could not be instantiated because it requires a design-time license.
Any one know how to get a "design-time license" for the MSFlexGrid control.
I want to create a simple program and I'm trying to do this with run-time design.with this form, when you click on the button1 with the caption(Text) "Show Another Form", another form will be created with this code:
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click[code]....
How can I exit the form I've created when you click on the Cancel Button. The code I've provided doesn't work.
I created a custom control (inherited from a panel). Then I created some other custom control (textboxes)
I add the panel control to the form, then I add some custom textboxes inside the panel.
Now, if I remove the panel, the custom textboxes don't move. I think, because the custom panel control isn't the parent control of the custom textboxes.
How can I modify my custom textbox class, if I add the textbox to a form, to a panel, to a container, it should have that container as parent.
I know how to set flowdirection at runtime, but how can I set it while designing a form?

View 2 RepliesI'm creating a usercontrol with a splitcontainer. I can reposition the split when running, but when designing on a form I can't adjust the position graphically, I can only do it by typing a new SplitterDistance. Is there a way to get a grip on that position at design time?
View 10 Repliessetting the default value for an integer attribute of a custom control seems to have stopped working. The following code adds the Maximum attribute to the design-time properties table, but the default value pops up as 0, not 99:

View 8 RepliesWe're developing a WPF & MVVM application that requires multi-language support. On each control with static text, we're using a converter to do a lookup for the appropriate word for the user's language.
However, this means that each control does not display any text. This causes some irritation for the UI developers at design-time. Is there any way to display design-time text?
For example:
<TextBlock>
<TextBlock.Text>
<Binding Converter="{StaticResource Translator}"
Path="Controller"
ConverterParameter="Search for" />
</TextBlock.Text>
</TextBlock>
How can I make this converter execute at design time to display the translated converter parameter?
I have a form that is used at design-time to configure various properties. I've tried two ways to do a form-level catch all exception:
(1) I add a handler to Application.ThreadException in the constructor.
(2) I wrap the Show method, of the form, in a Try/Catch block
Both of these work at run-time when I test by adding a property grid to a form and set my component as the SelectedObject. However, at design-time the form simply closes with no message whatsoever; neither my message nor any message explaining that there is an unhandled exception. This is not about debugging at design-time. It's about how to present the user with a friendly message when my type editor encounters an unhandled exception.
Now as the title says, I'm looking for guidance on some design-time support for the many custom controls I'm working on at the moment.At the moment I'm 3 months in on a Business and Inventory management system for my mothers business. It contains many, many custom controls I had to build from scratch because the ones provided just didn't cut it for what I needed. Now one in particular is a tab page control. Just as the provided TabControl Visual Studios supply's us. It has a lot of design time control. Such as clicking the tabs and adding controls to the panels being brought to front by the corresponding tab being clicked. I had a friend of mine try to show me what I had to do, but the way I had already built my control would have made it difficult - His words, so he never officially showed me anything. If it is true what he said then I can skip that, no problem. But adding the controls to the panels during design time I must have, but cannot seem to find anything through Google searches, text books or even kids majoring in software engineering.
View 4 RepliesI'm using Visual Studio 2008 Pro (.Net 3.5 SP1). I'm trying to make some MDI child forms in a Windows project (VB) and cannot find any "MDI Child" or "MDI Parent" property for any form.
How can I designate a form as an MDI Child at design time?
I've read the help files and they reference either an "MDI Parent" or "MDI Child" property but I cannot find those properties in the property list of any form.
