.NET Have Built-in Techniques For More Complicated Forms Of Iteration

Jun 11, 2011

Does .NET have built-in techniques for more complicated forms of iteration like the following:

1. Iterate over rearrangements of a list.

2. Iterate over subsets of a list.

3. Iterate over all indexes of a multidimensional list.

4. Iterate over all "combinations" of a list, i.e. all subsets of a list of a given length, where subsets that differs only in their ordering occur only once total.

I recently had cause to do (1) and my method was ugly, slow, tedious, and generalized poorly, which is why I ask. I can think of better ways, but it was garbage code anyway [brute force checking that there are precisely 576 seven-digit numbers made up of 1, 2, 3, 4, 5, 6, and 7 that are also divisible by 11]. The others are just for my own curiosity.

.net - Tidying A Complicated If-else Statement?

Apr 20, 2011

I'm trying to find a tidy way to set a string using an if else statement according to a numeric value. The only complication is that there is a possibility that this value may contain text. So it needs to handle that situation too.

So this is the basic code:

If cint(QtyShop) > 0 Then
msg = "Stock found in this shop"

Complicated To Convert Program From VB 6 To .Net?

Nov 15, 2010

I have a program I made in VB 6 which has probably hundreds of thousands of lines of code.

Is it complicated to convert it to VB.Net or is it not worth it?

My main problem is that VB 6 doesn't work in Win 7 so I need to use the XP emulator each time I make an update.

VS 2010 Drawing Complicated Pattern

Aug 13, 2010

I am refining my VS2010 control renderers and I'm working on the TabControl at the moment. If you take a screenshot of the VS2010 IDE and zoom in on the background of the TabControl (where there are no tabs), then you might see that it consists of a pattern of dots with a slightly different color than the surrounding background. I am trying to draw these dots (yes, I'm going for perfection), but I cannot find a brush that allows me to do this.I am pretty sure I'd have to use a HatchBrush with the right HatchStyle, but I cannot find a matching style.Here is a screenshot showing:

1. The VS2010 background I'm trying to draw (higher contrast and brightness otherwise it's hardly visible),

2. The HatchStyle that is closest to this (DottedDiamond)

3. Why this HatchStyle is not correct (it's missing dots where the green dots are, which I photoshopped in).

Now of course I'm going to have to draw the pattern twice (there are two patterns, offset by 1 pixel, with a slightly different color), but the more pressing problem is the green dots seen in the third image. They aren't there with the DottedDiamond style, and no other style (I think I've tried them all, but hey I might have missed some..) produces a better output.

Techniques To Control Stack Overflows?

Aug 20, 2011

Basically, my program will try to generate the list of all possible lowercase 5-letter words. Including all combinations that clearly are not real words like jshcc or mmdzq.

I do that by stacking up a massive amount of calls for a function, which does the word work.

But that's simply too much, and I get a stack overflow error.

Development Techniques - Make A Program That Can Be Used With Plugins?

Aug 19, 2010

While I've mainly been developing small applications for personal use, I stumbled upon making a touchscreen application for a close friend. While he is not very good at programming, he is pretty well at drawing/etc... So, I thought about expanding my horizons some.I already have code that loads images from a folder, and made that folder changeable via the program, so in effect, probably a horribly coded way of skinning some parts of the program (the buttons). But then I though about it some more and really wanted to learn a better way to make my programs 'expandable'.I have begun searching about how to make a program that can be used with plugins, how to make plugins, and so on... I am researching about dynamically changing controls and other things, so that when resolutions change, I don't have to code each individual buttons new size/location, and, most importantly, a way to implement patching/app upgrades...

C# - Preferred Techniques For Passing Objects Which Clients May Invalidate

Jan 31, 2012

I have adopted a technique where I pass existing objects to forms so that they can display the object's content and allow the user to alter it if necessary. The form is not bound to the object, so when it comes time to act, the form sweeps up the content of its controls and puts them into the object. The object is then validated and any issues reported to the user. If the object is valid, it may be handed back to the caller so the caller can refresh a view/list/etc.

So far, so good. However, if the form's content, or lack of, creates an invalid object and the user does not correct it, maybe cancelling the form, there's a chance the form will hand an invalid object back to the caller. This is not good.

Essentially I'm looking for an elegant and efficient way of either leaving the object as it was or rolling back if the user cancels the form/action.

I have considered a range of techniques, each with many pros and cons. I'm keen to consider some other views.

List View Techniques - Populate The Corresponding Data Elements On Another Form?

Jul 18, 2011

I have the following "contact" data (exampled below) stored in an xml file.I've created a frmContacts windows form and placed a list box control inside it.I'm new to the list box but plan to have the users manage the list by letting them add, delete, and pick from it. For searching there should also be a sort function/button (by last name then first name).If the user deletes from the list the corresponding data in the file will be deleted.If the user picks from or adds to the list, I'd like to find the best way to populate the corresponding data elements on another form (i.e., in their respective text boxes). This will include the ability to edit/save from this other form too.

DataGridViewColumn Iteration Speed?

Jun 13, 2012

I have noticed that when iterating DataGridViewColumns, the speed is greatly reduced if the columns are visible.

For Each col As DataGridViewColumn In cData.DataGridView.Columns
col.Visible = visible
Next

If visible is set to false (and all columns are all currently visible), iterating 264 columns takes around 0.35s, however, if visible is set to true (and all columns are currently invisible), the same process takes around 30s.Does anyone know what would be causing the extra time?Could it something internal to the DataGridView Control?

Iteration Of Class Variables?

Sep 23, 2011

Background: I am working on an ASP.net project that basically fills out a form from user input. The generated form (for reasons which I have no control over) must be a JPEG or TIFF. So the user fills out the web form, which takes all of the input values and meges them into a blank image (jpeg) of the form. Using System.Drawing, it merges all of the text onto the form at designated Points. The points are defined as variables which are modified at runtime to compensate for the resolution of the image (in case it get modified/re-generated at a different dpi). All of this is working fine.

Problem: Currently I have a Sub that determines the dpi of the master image, then adjusts the Points accordingly. However, there are ~50 variables that have to be adjusted. So currently I have the Sub go thru each point variable and manually adjust the X & Y values. I have been working on a Sub that will iterate thru all of the Point variables and do adjustment. Here's a functional sample of what I have working:Imports System.Drawing

Partial Class test Inherits System.Web.UI.Page

[Code]...

This works...sort of. It allows me to grab each variable and modify it, but only in the instance. The original variable in the class is unchanged. Which means that when the program gets to the point where it's drawing text to the image, the points are unmodified. my basic question is: Is it possible to modify the original variable using this sort of process? If not, is the best way to use these modified values to declare the new class instance at a global level, then have the Sub that draws the text use the instance versions of the variables?

I realize that I could define all of the points in an array which would be easy to loop thru and update, but I've named each point variable something meaningful to correspond to the related text to be drawn.

VS 2010 Any Tips Or Techniques For Debugging In Mouse Move Events / When Mouse Button Is Down / Has To Stay That Way?

Jun 6, 2011

I'm currently debugging a form that sets a flag when the mouse button is pressed, then clears the flag when the mouse button is released. As long as the mouse button is pressed, the user can move the mouse around and a few things happen depending on where they move. One of the things that happens is that a timer starts, or stops, and a few things change color depending on the mouse position. The timer starts when it should, then stops when it should, but once stopped, it is not re-starting when it should. I can verify that MouseMove events are getting through, because coloring changes as I move the mouse, as it should. This would be a simple thing to debug...except that it requires the darn mouse button to be down, and it uses the mouse move event. Anybody who has put a breakpoint in a mouse move event handler knows the issue: There are THOUSANDS of them. Worse yet, since the mouse button is necessary for switching to the IDE, as well as setting a breakpoint (technically, a keyboard shortcut could do this if I could shift focus), I can't wait for the problem to happen, then switch to the IDE and set a breakpoint to see what is happening then.Does anybody have any tips or techniques for debugging in mouse move events when the mouse button is down and has to stay that way? As it is, I'm going to have to write some funky code into the method just so that I have a place to get a breakpoint when I need it without breaking on every one of the mouse move events.

.net - Unexpected IQueryable Value After ForEach Iteration?

Apr 15, 2012

I'm flummoxed I'm using VB.Net, Linq, and a DataContext. My DataContext contains a table 'transactions'.

I first declare an IQueryable(Of transaction) and assign it to nothing. I build a predicate in a foreach loop and use a transactions.Where(predicate) to assign the IQueryable a value. If I do an IQueryable.ToList(), I get a number of items in the collection.

However, on the next iteration of the loop, the IQueryable.ToList() gives me 0 items.This is driving me crazy. I tried to use the LINQ to SQL Debug Visualizer with VS2010, (I recompiled the 2008 version with the new reference) but no dice - I can't see the SQl generated or what's inside the IQueryable.
