Visual Basic :: Transparency, BitBit() And Number Sorting

Sorting A Listbox By Number
Hi,

I've got a listbox that displays scores and the user's name next to it. I want to sort this listbox with the lowest number coming first... (regardless of what the person's name is - in other words... a highscore table)

I've found the list1.sorted command but that doesn't seem to work with numbers.

and I've tried a bubble sort using the following code but again... is not sorting the numbers in to order:

Code:
Private Sub SortListBox()
    Dim intCount As Integer
    Dim strSwap As String
    Dim boolDidSwap As Boolean
    Dim intI As Integer

    intCount = LstHighScores.ListCount - 1

    Do
        boolDidSwap = False

        intCount = intCount - 1

        For intI = 0 To intCount
            If LstHighScores.List(intI) > LstHighScores.List(intI + 1) Then
                strSwap = LstHighScores.List(intI)
                LstHighScores.List(intI) = LstHighScores.List(intI + 1)
                LstHighScores.List(intI + 1) = strSwap

                boolDidSwap = True
            End If
        Next intI
    Loop While boolDidSwap
End Sub

Any help here would be grately appreciated.. thanks

Help With BitBit
Hello,

I am new to the gaming scene. I have picked up a little here and though however. I was wonder how to determine the size of the map window? Uhh...How to make it Show more of the map? The example I am looking at only has a small block, but I want to increase it to view more map at a time. Any suggestions on where to start?

Sorting Fields (number) Problem
Hey all,

I have a slight problem. I have some records in a table with a field that stores numbers. Some of the records do not have an entry in that field and I have left them blank. However, when I run a query and sort the number column ascendingly, the records with the blank value are above the ones with actual values in them. I want the records with number values to be before the records with the blank values and in ascending order.

The problem for me is that it is part of a query and I would prefer it if I didn't have to write some code to do it, I am trying to keep my UI as simple as possible.

Holding Number And Strings, Then Sorting
Is there a way to load the contents of a text file of format:
"name","score" - .e.g. "jon","6"
and then display them in a listbox, sorted by the score (highest first) and preferably given a rank. e.g. 1. Amy - 20

Thanks (sorry for the short post - I am working to a strict timescale and am trying to complete as fast as possible)

Sorting Listview W/ Text && Number?
Ok, I can easily sort my listview by the columnindex if it is text. However, some of my columns contain numbers. I had a module from Planetsourcecode that did this, but there was one major flaw. Everything sorted fine, but after it was sorted the items would be mixed up. Here's an example of what I mean:

Say we start out sorted lvwascending. "Bob" is the second item in the listview. Now we sort by lvwdescending. Now "York" is the second item right? but when you execute something on York you get the information on "Bob". Any help with sorting without things getting mixed up is extremely appreciated.

Working With BitBit
Hi,

I've just began using BitBit now, so i'm not too good, i'm progressing slightly, but have a small problem...

Anyway, i've began making a square grid based maze game to get used to the functions of BitBit and cant seem to get something right, the game currently in no way resembles a maze, because I haven't started that bit yet...

To move the sprite properly, on a square-based grid i have set up an intXNow value to work with the intX, so that the character only moves so far at a time, by presetting intX to 10, then everytime you press to move, intXNow updates itself to equal intX, then runs the movement part on a timer...

Code:
Do Until intX >= intXNow + 50

-- movement code --

Loop

This works fine, but when you run it the first time he moves, he does four steps, the next time he does 5 steps, so he is no longer in the center of the x-axis grid...

I'm not sure what I have done wrong with this code.

Can somebody please look at my source code and tell me what i have done wrong to cause this uneven movement.

The source is in the zip below...

Your Help Is Greatly Appreciated.

BitBit With MSChart
Can you use BitBit to make a realtime MSChart Graph not flicker? I've looked through some of the threads here and they seem to mainly use pictureboxes for gaming. Is the principle the same, if so how would i implemet it?

Sorting Serial Number In Data Reports
I am using Data Reports via Data Environment.,
I wrote this query to print SERIAL NUMBER on the data reports...
Please note that I am not using any temporary table to extract any bogus serial number entry... this code representing serial number via SQL Query....

now the problem is this that the serial number column is a virtual column created by SQL query which is associated with the ID(which is unique) which must be sorted in ascending order with this ID .... but it is in descending order.....

Anyone can solve it....??????

DLLImport - GDI32.dll - BitBit -
hi,
the Issue is ,

I would like to crop part of image. (I know the rectangle to be cropped from the tiff image). I tried DrawImage. But some Pixel Information is lost.

So I am trying to use BitBit approach.

My Code is ::::::

---------------Declaration - ----------------------

<DllImport("gdi32.dll", EntryPoint:="BitBlt", SetLastError:=True, _
CharSet:=CharSet.Unicode, ExactSpelling:=True, _

ByVal nXSrc As Integer, _
ByVal nYSrc As Integer, _
ByVal dwRop As Int32)
End Function
Private Const SRCCOPY = &HCC0020 ' (DWORD) dest = source
-----------------------

My function for cropping is
----------------------------
Dim g1 As Graphics = PictureBox1.CreateGraphics()
Dim imgCrop As New Bitmap(200, 200)
Dim g2 As Graphics = Graphics.FromImage(imgCrop)
Dim dc1 As IntPtr = g1.GetHdc()
Dim dc2 As IntPtr = g2.GetHdc()
BitBlt(dc2, 0, 0, 200, 200, dc1, 100, 200, SRCCOPY)
g1.ReleaseHdc(dc1)
g2.ReleaseHdc(dc2)
imgCrop.Save("c:Captured.jpg", ImageFormat.Jpeg)
MsgBox("Finished Saving Image")

------------
Error Msg :::

Anyone has idea about where I am doing wrong. Or any better approach for this

Make Bitmap Transparent With BitBit
Hi all -
Lets say I have a bitmap with a region that has been marked with a certain color to detone a transparent area - how could I go about BitBit'ing on top of another picture in VB so that the solid color becomes transparent? THanks

Hmmm....bitbit Seems Easier Than Trying To Do Maps With An Editor?
Hello again,

I got my map working with bitbit, but the things are super small. I can barely see em hehe, anyone got a site that will show the break down of bitbit that what represents what? I had to just play with some and just do a row of numbers and see what I came out with. The last question is, to increase the actual size my bits display at do I need to increase the pixel size?

Thx for any help.

Questions: BitBit Moving, Walkmasks And Item Pickups.
Ok, so far have i quickly created a small program where a picture(the guy you control) moves instantly to the location of your click. Theres 3 things i must now:
1. How can i make my guy move slowly to the targeted location? not instantly.

2.How can i create walkmasks? Forexample if i create a tree, and i dont want my guy to walk right through the tree but around it.

3.How can i make my character pick up items? Forexample how can i make my guy get 10 score-points when he moves over an item, which in reality is a picture.

Edit*
I use BitBit.
This is not going to be a real game, iam just testing things out before i start creating a game.
Nothing is animated.

Sorting Large Number Of Large Text Files
Hi,
I have around 500 text files (csv format). Each file is ca. 5MB and sorted by a timestamp. my application needs to playback all these files line by line but sorted by time.my goal is not to put all files in memory, use a sorting algorithm, create one sorted output file and then read from the output file.
I am rather thinking of sorting the files as they stream. For this I would only need to know in each file the time stamps of the current lines and compare them to each other.
what is the best way to do this? any ideas?
thanks

ListBox Sorting Numerically / Array Sorting
I've made a game and as a finishing touch I want to add a network scoreboard. I can simply do this by writing to a textfile on the network using:

VB Code:
Open App.Path & "Scores able.txt" For Append As #3Write #3, frmMain.lblName, frmMain.lblSClose #3

and it writes "Fred","6" with 6 being the score.

This works great but I now want to have a leaderboard on start-up and a listbox displaying all scores. I can do open for input and then plonk the contents of the textbox in the listbox, but I can't make it sort numerically, so the highest score is at the top. Alphabetical sorting doesn't work unsuprisingly! Is there an easy way to do this? This is what I currently have:

VB Code:
Open App.Path & "Scores able.txt" For Input As #1Do While Not EOF(1)Dim strIn As StringDim strInS As StringInput #1, strIn, strInSlstLeaders.AddItem (strInS & " - " & strIn)LoopClose #1

Perhaps I could put them into an array and then is there a way of sorting this?

I also want a Top-Ten leadboard, but I assume this would be easy to make once the valuse are sorted. It would also be a nice touch to tell the player their rank after the game too.

Any ideas?
Thanks!

Transparency In WMF And GIF
I'm trying to save a WMF as a GIF using GDI+ but

bitmap.loadfromfile wmffile
bitmap savetofile giffile, gifcodec,0

loses the transparency.

Should the transparency be preserved automatically?

Do I have to find the transparent color in the wmf so I can set it in the gif? If so, how do I do that?

Howdy Doo

Ok How do i get it so when a user selects an image on 'Form1'
Example 1:http://dale.host.sk/1.gif

Then once they select that image, they click a button to goto the next form 'Form2' then they select another image
Example 2:http://dale.host.sk/2.gif

Then once thats selected it goes to 'Form3' which shows the result (Form1 & Form2 image have been merged together (transparency)) and then it allows the user to save that image.
Example 3:http://dale.host.sk/3.gif

...

Transparency
ive used someones code to make a form transparent
when it fires up.

I also have a gif with rounded edges because i made the
edges pink and made them transparent in a GIF editing
program i have.

I added it into a Image Control thinking yeh its edges are
transparent now my form will look like it has rounded edges
but..............i was wrong it took me awhile to figure out
but it seems the IMAGE CONTROLS corners on the transparent
parts of the GIF image are visible which makes it look crappy
does anybody know another way i could go about this?

Transparency
This is what I need to do:
Make a form with a transparent background (you can see the desktop and windows behind the form)
Keep all of the controls Opaque
Allow a transparent Gif in an Image control to become transparent as well

Does anybody know how to do any of these? The first 2 are easy... 3rd keeps bugging me

Transparency Help
Ok, so what i am doing is making a map program - i want to add circles to positions on a map. the program works by drawing these circles on the picturebox using .circle, but now i ran into a problem. how can i move these circles once they have been drawn? i have thought of maybe having a transparent picturebox placed on top of the actual picturebox that holds the map, then draw the circles on that. (if i wanted to reposition one circle, i could easily delete its pixels and still have the map benith). but i do not know how to make a transparent picturebox that does this. i also thought of bitblt, but when i try to save the image what is blitted is not part of the image. so it seems that a transprent picturebox may work better (then for saving just merge the two pictureboxes). any help is appreciated!

I found some code at PSC that showed how to make your forms transparent. However it only worked in Windows 2000 and Windows XP. The only form transparency code i found for other Win OS was taking a screenshot of the background then blending the background with the form.

I know this has been asked many times but how do you bitblt a transparant image without creating a mask for every picture and not using Transparantblt.

I have an image control contined within the picturebox. this has a picture of a small fish.the fish's background is blue, but I want it to be invisible, so you can see the bear behind it. I can do this on photoshop, but I want visual basic to do it. How?

I'm not sure what the best way pf achieveing the affect I want is but I was thinking of using a transparent form.

My aim is to display a game interface with semi transparent sections over a map.

I want the buttons and the general interface to be semi transparent so the map can be see through it and then the rest of the area fully transparent.

Any help would be apreacited. I was think I could try something along the lines of BitBlt mask when black and white make transparent but I couldn't do it.

Thanks Ben
