C# - A Style That Activates Depending On Another Style?
Dec 24, 2010I am trying to make a style that only gets applied if the parent element of the element that the style refers to, has another specific style. Kind of like in CSS where you can do ".class1 .class2" to specify that the "class2" theme only applies if it is within an element with the class "class1". I do not wish to use any form of external DLLs or libraries for this task. I want to know if it's possible to implement on my own.
I've tried using MultiTriggers with no luck. I have a style that applies to all TextBlocks. I want the textblock to do the following: If the font-size of the textblock is 11 and the parent element's style is "PinnedSuggestion", set the foreground color to "#FF505050". If the font-size of the textblock is 11 and the parent element's style is "Suggestion", set the foreground color to "#FFCCCCCC". The conditions that I have tried to write to make this work, are as follows (the font-size condition is true, but the other one is not). The conditions are inside a style that applies to all textblocks in general.

Change The Button Style And Button Text Style On Mouse Rollover?
Mar 7, 2009I am creating an application and am very new to VB. I have 4 buttons on my form which is like my applications main menu. I would like that each of the buttons behaves in the following way when there is a mouse rollover: The Button back color is changed from the default to Red The Button text is changed to Blue, Bold, and increases in font size I would also like all the buttons to go back to their initial state when the mouse leaves.
Another thing, instead of me writing code for each of the buttons event handlers (Mouse Hovers, and Mouse Leaves) is there a way I can write this code once, maybe as a function and then always call it for any button that I create from here on so that any new buttons take on this behaviour.

View 8 RepliesUncle Bob Style OOP In .NET?
Nov 17, 2009I've been professionally writing VB.NET software for seven years. However, I don't have a strong computer science background - four courses while studying education at university in the 90s that gave me some CS basics and exposure to Pascal, C and Lisp. Anyway, there are a whole bunch of practices that I'm missing - testing, patterns, "real" object-oriented design, etc and I'm trying to pick them up. If you look at most of my applications, you find blocks of fairly old-school procedural code being triggered by form events. Where I write my own classes, I'm mostly using them as data-structures with overloaded New() methods and maybe a custom output method. I consider myself quite proficient at this kind of work and none of my employers has had any problems with it. But it's not really right and I'd like to learn more of the craft of my trade.
Since the early 90s, I've looked at several different intro to objects kind of documents -- books, tutorials, etc. They seem to all use dogs and cars as analogies and examples with tons of responsibilities per object. And they've never stuck with me even as I wanted to learn from them.Lately, I've been reading "Uncle" Bob Martin's notions of OOD and I like what I see. But it's hard for me to follow the C/Java syntax and I get hung up on that difficulty rather than just ingesting it smoothly. So I'm looking for good sources with VB examples because that is (by far!) the syntax with which I am most comfortable. There's not much around. The stuff that I find doesn't seem to advocate or exemplify e.g. the Single Responsibility Principle.
I've been looking for books, but they mostly seem like they're either OOP and not in VB or VB and not (really) OOP. I've checked out the following topics here: 1, 2 and 3 -- among others. I've scrutinized the Amazon reviews of most of the books listed in those threads and keep coming up with reasons to suspect that they aren't really what I'm looking for.
So, any ideas? If you're going to suggest a book, I'd like to hear how well it fits the needs that I've outlined. If you think I'm on the wrong track, I guess I'd be interested to hear why. If you have other suggestions on how to pursue this avenue of improvement, that too would be great.

View 1 RepliesVB GridView Control Does Not Allow Code To Access Column When Column Has Visible Property Set To False
Apr 1, 2010VB GridView control will not allow code in the vb code file to access a data column that has its visible property set to false. When it is set to true, the data column can be accessed with no problem. Any suggestions as to how to correct this? I have looked through the documentation, text books, and I have not found anything that gave me any clue as to what the problem could be. I thought that the property was just applied to the column, not that it would remove the column from being accessible.

View 1 RepliesDatagridview - Sort Datagrid View Column With Numbers And Texts On Column Header Click?
Feb 13, 2012It seems that on clicking datagridview column header, the column will be automatically sorted based on the column type. I have a column showing some numbers. If column type is string, it sorts "1","20","3" into "1","20","3". If column type is double, it sorts into "1","3","20" which is the result that I want. However, there might be some erros in the numbers and error messages(text) will show in the cell instead of numbers. So I cannot set the column type as double. I want to ignore these error messages and sort all the numbers. How can I do this?
Also, I need to add some background colors to different rows in datagridview. So in the column header click event, I call the bkgColor Sub to achieve this. My question is that how can I override the sorting method in this event?
