I am working in .Net 2010 framework 2.0 I want to place the constant string for a color property in form designer like GradientBeginColor = MyColor in form designer.
View 1 RepliesI am working in vb.net 2010 framework 2.0I am using a custom panel and painting it. For this i am using the gradientbegincolor and gradientendcolor (as color) properties in custom panelWhat i want is gradientbegincolor and gradientendcolor in form designer should not store any color instead it should store the name for these color
View 12 RepliesI know lots of you have had problems with the form designer giving errors and refusing to show the actual form, mostly because of some transition in software i take it (i aren't a Full time programmer, its just a hobby.)My problem is similar, vb refuses to show me my form and now i have even more problems.the last thing i did before this happened was try to add an imagebox to the form.Heres a few errors i get:every label i have is no longer declared?event 'load' cannot be found- My other problem is, i managed to close the designer window during this problem and i cant remember how to get it back up

View 2 RepliesI am attempting to update an existing winforms application, that was created with a dataset control on all the winforms pages. I have ported it from VS 2008 to VS 2010 and I need to update the database section and connect it to the SQL backend using traditional code method.In the Solution explorer, when I click on the Dataset files, and click "Exclude From project" I am unable to build the project.Is it advisable to comment out the code lines that refer to the dataset in the .designer.vb files?
View 1 RepliesMy self and most everyone else on our team is having the same issue with VS2008. The designer will not render many forms in designer mode. Currently I am getting this error "The type 'Team.CAD.UI.My.Resources.Resources' has not property named 'view_16'" Well veiw_16 is in the resouces file.
View 2 RepliesI know that with some of the programs I use, when you click on an item to change it's color, the color dialog will actually show the current color and it's rgb value.
I'd like to do that in my application but can't find the answer on how you do it.
To change the backcolor on a textbox, the user double clicks the box and it shows the color dialog.
I think I have all the properties set right -- fully open to show custom colors etc.
BUT, it doesn't show the current color.
They all have 0 0 0 rgb.
The company has a Visual Studio 2010 Ultimate project that is written in Visual Basic. The project has several strings in the resources file (Resources.resx). One of those strings (VersionSuffix) contains "" when we are distributing a normal version of our product and "BETA" when we are distributing a beta version of our product. Most of the time we distribute a normal version of our product. Therefore, most of the time the resource string VersionSuffix contains "".
Recently, we attempted to distribute a beta version of our product. Therefore, we changed resource string VersionSuffix from "" to "BETA". However, it quickly became apparent that the resource string VersionSuffix was being used as the default value for several control properties in the form designer. For example, if I draw a rich textbox on a form then file FORMNAME.Designer.vb will contain the following.
Me.RichTextBox1.Location = New System.Drawing.Point(286, 306)
Me.RichTextBox1.Name = "RichTextBox1"
Me.RichTextBox1.Size = New System.Drawing.Size(134, 33)
Me.RichTextBox1.TabIndex = 32
Me.RichTextBox1.Text = Global.PROJECTNAME.My.Resources.Resources.VersionSuffix
We are unable to find anything anywhere that indicates that this resource string should be used as the default value for control properties. Therefore, we have no idea why this resource string is being used for this purpose. We would like to change the control property assignments in the designer from Me.RichTextBox1.Text = Global.PROJECTNAME.My.Resources.Resources.VersionSuffix
Me.RichTextBox1.Text = "" However, we don't know why these strange assignments are being made. Therefore, as soon as someone adds another control the problem will most likely return. Does anyone know why this is happening and how to prevent it from happening again?
I have strMyColor = "Red".I would like to make lblMyLabel.BackColor to be red.Without using a variable the code would be this:
lblMyLabel.BackColor=Color.Red
I tried using the variable like this: lblMyLabel.backcolor="Color." & strMyColor
But the error is that a string can't be converted to System.Draw.Color. I understand that, as the string "Color.Red" is not the same as the VB constant Color.Red.Is there a way I can construct a valid vbConstant from a string?
I have two tables in my database: Table1: Table1ID [Primary Key, Auto Number] Name Surname Table2: Table2ID [Primary Key] BirthDate HireDate I have created a one-to-one relationship between these two tables [Table1ID <==> Table2ID]. When I create a dataset using these tables, designer doesn't show one-to-one relationship lines? It shows one-to-many relationship lines. Is this normal? Is it always shows every relationship type like that or my one-to-one relationship wrong? I'm using VB.NET 2008 Express, SQL Server 2008 Express .

I want to pass an optional parameter to a function of type System.Drawing.Color.

When building a class library which contains many classes, all classes uses a lot of common constants and functions, what is the best to do:
1- Declare these constants and functions as public in a module.
2- In each class declare constants and functions used by individual class as private.
The first choice is good for easy and fast implementation, but re-using a class in a different project will require importing the module to the other project.The second choice require a lot of copy/paste for code snippet but a class can be re-used in different project easily.
I'd like to understand why one type can't be converted to another type inside a constant expression.

View 1 RepliesI have the following line of code
Dim a As String = ""
And the Refactor suggests replacing the "" with String.Empty
It is a kind of Refactoring but why? Since I am a newbie in the future declarations of mine should I better use the String.Empty ?
suppose I have variables named A1, A2, A3 ... B1, B2, B3 ... Z97, Z98, Z99. I have a certain operation I want to do using each one in turn. I CAN write a line of code for every single variable, but this will get pretty tedious. I'd prefer it if I can make a function that takes the letter and the number as arguments. So, if it gets the arguments "E" and "10" it will perform the operation on variable E10. What is the syntax for this? say a simple operation such as: result = E10 * 3 Is the syntax any different if I use constants instead of variables?
View 3 RepliesWhen developing ASP.NET websites (using VB.NET web forms) - a lot of my time is spend writing CSS files and they always seem to get messy (code duplication) and very long.
All I want to achieve is to be able to manipulate the CSS using VB.NET code in the following ways:
Use an integer variable to store my "golden" number 7 and use that for width, padding, margin etc where needed
Use string variables to store my "golden" hex color codes e.g. "#44C5F2" and use them for color, background-color, border-color etc. where needed Use an integer variable to set the height of an element and have four child elements each with height: mynum / 4
I just want to use basic VB.net number and string manipulation in order to create a CSS file on the fly.
I understand that the end product - the CSS file shouldn't change much - it should at most change on a daily basis otherwise caching couldn't be used.[code]...
I noticed that if I leave off the terminating double quote for a string constant in Visual Studio 2010, there is no error or even a warning, i.e.
Dim foo as String = "hi
However, the continuous integration tool we are using flags an error:
error BC30648: String constants must end with a double quote.
Is there some language rule in VB.Net that makes a terminating double quote optional "sometimes"? Is there some setting in Visual Studio that will make it flag this as an error, so I can avoid "breaking the build" in this way?

I have a multi-lined string message that needs to be added to the Resources.resx file of the project. Currently I'm achieving this some thing like this MessageBox(My.Resources.MyMsg1 & vbNewLine & My.Resources.MyMsg2 ). This works.However I'd like to have the entire message in one resource string rather than adding two resources strings to the Resources.resx file.I've tried using' but no luck..message displays as "My message.Rest of the message".I've also tried manually adding a new line in the Resources.resx file. ( by doing "My message.<Shift+Enter>Rest of the message" But message is adding an additional space before the message in the second line.
View 8 RepliesThis may take some explaining but the concept is pretty simple. A user will select a file which contains data that they wish to extract from, so keeping it simple they pick a file like so:
[Code]....
So, I need to show the user the file, allow them to select a line to match and/or extract from. So they select the first line ready for a match, they then select a word/s to mark as a constant for matching, so in this case it would be: MyGroup A simple version for text match would be like "MyGroup *" Now, I need to convert this to regex dynamically (I assume its the best method), its not a one off, the data that is selected is all open and up to user selection. There could be multiple selections and multiple extractions on the same line!

How can i use the color dialogue to return the color selected as a string? So if i was to select red i would like the return to be "Red" and so on so fourth.Another thing i would like to ask is if it is possible to return the color selected as a string in hex color code form (like what is used in HTML for example #FFFFFF, #000000 and so on so fourth).I have a feeling though that it can only be returned as R G B integers but maybe there is a way of converting these to hex color codes?
View 11 RepliesI want the background of my form to be the same color as the window frame color that the user selects, even if that changes. I selected System->WindowFrame as my background color, but it always remains a dark grey, regardless of what I have my window color set to. How else would I achieve what I want? I assumed I was doing it the correct way. Do I actually need code that gets the system window color and then apply it?
