View 1 RepliesI have developed an applcation using vb.net, its a windows based or Desktop Application. In one of the Form i am displaying the new complaints in a DataGrid With Employee Names.
Now, Each employee has a prority set for him, so depending upon the priority I want to assign a different color to Datagrid row.
I have a table, the color of the whole row depends on one of the two columns. Table: | ID | Name | Date | Ext Date |
Where Date color depend on the value, <15 is green, <30 is yellow and >30 is red. While Ext Date depends on value, >-14 is red, >-30 is yellow, <-29 is green and without Ext Date value will follow Date value.
I tried to put Switch in IIf but returns no color at all.
=IIf(Fields!countexten.Value="-",Switch(Fields!countdate.Value < 15, "Green", Fields!countdate.Value <30, "Yellow", Fields!countdate.Value > 29, "Red"),Switch(Fields!countexten.Value>-14, "Red", Fields!countexten.Value>-30, "Yellow", Fields!countexten.Value<-29, "Green"))
I want to pass an optional parameter to a function of type System.Drawing.Color. The problem I am having is that when I declare the function it says "Constant expression is required" but I have tried variations of the following, including integers, full qualified indentifiers, even old vbWhite constants to no avail.

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.
Im using a dataset to display data in a datagrid from a sql server DB. One of the colums I have in my datagrid is "Status" the table adapter sql statment selects certain items based on whether there open or closed e.g "where = Open ". I want to remove this row entirely and instead of displaying open or closed for status column, display the open/ closed results in colour on the datagrid. Im really not sure how to go about this whether i need to do it in the table adapter or some sort of property. I presume i need to write a sql statement and selct the identity of the row where x= open etc , is there a way of assigning a colour in sql statement so it displays on my vb form ?

View 2 RepliesAlright inside of a combo box I have a list of colors and I want to change the background color of the combo box to the selected color...basically this... but im not sure what the problem is here anyone have some advice or is this not possible?
CBLinerColor.BackColor() = CBLinerColor.Items.Item(0)
Basically i want dynamic code that will change the color depending on the items in the box.
I 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?
View 4 RepliesI have a array of pixels. And I would like to Quantize them.
For Example
FF00FF,00FFFF stuff like that, but most are custom colors and are not a standard 256 color palette. So I need code to convert a color to a 256 color. I dont have any idea on how to do this, but thats why I came here. I do not want to use System.Graphics.Image.Palette or anything like that as this project uses arrays for images. I would like to if at all possible be able to convert a R, G, B color to 8bit, 16bit, 256bit and possibly use the HSL or NeuQuant method or something close to that, or maybe even some other methods of doing it. I do need to be able to do this for a single pixel, but I will also need a method for a array of them.

View 2 RepliesI 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?

[Code]....
[URL] That way if the string that is not recognised that is passed to Color.FromName it returns a SolidColor of
Color.Black = Color.FromARGB(255,0,0,0)
That way, Forms and controls that only support SolidColors are supported.Installing VB6 on Windows 7?
I mean why? I mean to organize things I often turn modules into classes where all the methods are share.But then I thought, why not organize them into namespace?But then we can't declare constant in namespace.
