Attempting To Change/generate Pictures Pixel-by-pixel At Run-time...
Hello all,

I am fairly new to VB (especially using ActiveX with VB), and I am attempting to make a little tile-based RPG (like Dragon Warrior or The Legend of Zelda). Anyway, I am wondering how to change StdPicture objects at run-time.

Scenario:

Each tile has its own graphic (StdPicture object). I would like to be able to call a sub that takes this StdPicture and then increases the amount of red (RGB color) in the image. I can get this to work for pictures in PictureBoxes, but I cannot figure out how to do this with StdPicture objects. Any help would be appreciated.

Thanks -- ^iMp^

Get The Pixel Size Of A Picture.
Hi there,

I have an picture with the pixel size is (99 x 131), I load it in a picturebox(autosize=true) then using these lines of code to get its width and height:

msgbox picture1.width
msgbox picture1.height

and I get these values : 1485, 1965

How can I get the actual size(99,131) of this picture in my code ?

Thanks a lot.

Form By Pixel Size?
Ok this might be a stupid question.

I am creating a form and adding a flash movie to it. I would like the movie to fill the form.

The movie was designed to be played inside a web popup which was originally designed at 570x295 pixels.

However, in vb, form sizes are not by pixel, right? For instance, height and width of a form goes into 3000's or so to get anywhere near that size.

What is the conversion? How would I make a form be 570x296 pixel size?

Calculating Size Of A Stretched Pixel
I'm using stretchblt to zoom in on a bitmap.

I'm trying to calculate how many pixels now make up what was once 1 pixel. Unfortunately, what I'm calculating and what StretchBlt is giving me are different. I don't have a good understanding of how StretchBlt works so maybe someone will see what I'm missing.

My example:

I'm selecting a box of pixels 20 X 20. I'm stretching it to 525 x 529.

So for my calculation of how many pixels will make up what was 1 pixel in the 20X20 image I used the following:

' NewPixWidth = OldWidth / NewWidth
26.25 = 525 / 20

However, when I look at the actual width that StretchBlt created a pixel is 25X25. This is causing me errors in my App because I am trying to calculate exactly which pixel of the unzoomed bitmap I'm on.

I think it is probably something in the way I'm calculating my new pixel width.

Does anyone have any ideas?

How To Size The Form Location In Pixel Value?
It makes me so confuse that,
The location setting(Top, Left) value seems not in pixel.
My resolution is 1280*1024.
but when I set left=700, the form is out of the screen!
How can I set it( or convert the pixel to that unit?)?

Besides, anyone can tell me how can I get the window size of EXCEL ?

Thank you so much!

Actual Drawn Pixel Size
There has been recent discussion on the XTVB forum here about the use of the TextWidth() and TextHeight() functions of the Form or a PictureBox. (These are also available in a UserControl). I have used these functions many times and know that they return values that are related to the text string being painted in a current font.

But these also return values that are closely related to the metrics of the font itself and not the actual pixel image of the text string. For example the TextHeight() will return the same value for a ".." string or for a "``" string. In a similar manner the TextWidth() will return values that include the horizontal spacing to the left and right of the glyph images includiing the excess right side or left side spacing that may exist in some fonts for strings like ")" or "(".

What I want to ask if anyone has done any work or discovered a API method for getting the actual drawn pixel height and width extents for a string as opposed to the values related to the font metrics. Clearly it is possible to actually 'Print' the text into a PictureBox and then scan the result (within the range of the TextWidth() and TextHeight() values) and look for the first non-background color columns from the left and right and rows from the top and bottom. However such coding in VB can be rather show in execution if this result is needed in certain cases that change dynamically in response to user mouse action.

For Example: I was working on a specialty re-sizable User Control where I was desiring to display a symbol from the Marlett Font on the user control such that I could maximize the symbol size on the control surface as opposed to accepting all the "white space" around the symbol. The attached image shows on the left what I would get in a certain sized bounding box if I scale the font size according to the TextHeight() and/or the TextWidth values when instead I want to scale the symbol image itself to the bounding box size.

Any suggestions???

Courier New Has Different Pixel Heights For Same Point Size On Different Printers?
I'm new at using the printer object. After going thru very close attention to making sure I could print a text page to certain spec's, things went to pot while testing on a different printer.

I need to know this because I am giving option to reprint any of the pages.

Are there different point heights using the same point size on different printers? I'm only using "Courier New" between 7 and 10 points.

If so, how do I determine what the point heights are?

Appreciate you answer and thanks

Find Size Of Picture Int Html File Based On Pixel
I would like to make a program which it will take as input a whole Html file and will compute the total size of text and pictures. I consider that a simple html file consists of simple text (data) and some pictures. My goal is to parse the Html file and calculate the amount of size of text and pictures.
For example the program must, if the total size of Html file is 10KB, to generate an output where the Size of text(data) is 3KB and the Size of Pictures is 7KB.
One of mine main problems is how to measure the size of pictures. Probably this task demands a procedure where it converts the pixel to bytes.

So

1. Navigate to a web page posted on the internet someplace
2. Find out the number of bytes that make up the html file itself (the ascii of the html page).
3. Find out the number of bytes that make up what has been added/included with the html file (meaning pictures).
4. Take 2 and 3 and add them together to get a final result of total bytes.

Could aynone give me a hand of help?



Could anyone give me a hand of help?

PictureBox Size Change With Form Size [Solved]
I have a toolbar and a statusbar on my form, i want the size of the picturebox to follow the size of the form. So this is my code

Code:
Private Sub Form_Resize()


If Me.WindowState <> 1 Then 'not minimized
    On Error Resume Next
    
    
    Picture1.Top = Toolbar1.Top + Toolbar1.Height
    
    Picture1.Left = 0
    
    Picture1.Width = StatusBar1.Width
    
    Picture1.Height = StatusBar1.Top - (Toolbar1.Top + Toolbar1.Height)
    
        
End If

End Sub



This works perfect if the window state is 0 (normal) if it is maximized the size of the picturebox is the same as it was before i maximized.

Below is the testcode

Change Font Size In RTB, But Not All Of It!
I have the code below to change the size of the selected font in a RichTextBox.

If the user selects a different size font part way through using the RTB, how do I get the text from that point on to be the newly selected size?
I have a combobox with the sizes available for the font.


Code:
Private Sub cmbFontSize_Click()
On Error GoTo ErrTrap

If Len(rtbNotes.SelText) > 0 Then
rtbNotes.SelFontSize = cmbFontSize.List(cmbFontSize.ListIndex)
rtbNotes.SetFocus
Else
''rtbNotes.SelFontSize = cmbFontSize.List(cmbFontSize.ListIndex)
End If

[VBA] Change Size Of Label
Hello,
I have an Access report. At the "onFormat" event I want to change the "height" of an element.
There is a line around this element (a box), so I check for the change of size.
So I tried:
Me.myElement.Height = 5
And this does work. I get a line (i don't even see the data).
But when I actually try to make the height very large for example 50, the maximum the box will grow on is whather space the text take.

How can I fix that ? Is there something I am doing wrong ?

The reason why I am trying to do this:
I have different info in my report
For example:
Info 1, Info 2, Info 3... and so on
When I generate my report each one of them is surrouned by a box (ie, border = solid).

Info 3 is a bit like a memo.
My problem right now is that the box around info 1 is not equal to the box around info 2 or info 3... I want to have all the boxes size to be equal to the largest.
So that's why I have to know how to set the height programatically so that when the report is generated it sets the heigh of the boxes to the height of the "tallest" box.
But if you have a way around let me know please !

thanks !


>>>>> UPDATE :
I fixed part of my problem.
I disabled the "Can grow" and "Can Shrink"
My issue now is for EACH detail i want to find the tallest size ( i know how to do that), but I don't know how in the "OnFormat" event do it for EACH detail in the report... right now it does it for everything... all the details box are the same....
please help,
thanks

>>>>> MORE UPDATE :

I did figure out to force the size of the fields. (the cangrow and canshrink have to be set to false)
My problem is that I want all the fiels to be the same size as the field with the tallest size.
The fields (Memo, and Description) are the tallest one no matter what.
So I want to do a check to see which one of the two is the tallest and then set the size of everything else equal to the tallest.

So right now I have in the OnFormat event:


If Me.Memo.Height > Me.Description.Height Then
Me.Field1.Height = Me.Memo.Height
Me.Field2.Height = Me.Memo.Height
Me.Field3.Height = Me.Memo.Height
Me.Field4.Height = Me.Memo.Height
Me.Field5.Height = Me.Memo.Height
Me.Field6.Height = Me.Memo.Height

Else
Me.Field1.Height = Me.Description.Height
Me.Field2.Height = Me.Description.Height
Me.Field3.Height = Me.Description.Height
Me.Field4.Height = Me.Description.Height
Me.Field5.Height = Me.Description.Height
Me.Field6.Height = Me.Description.Height

End If


PROBLEMS:
Right now this does not work.
BUT if I give a number instead of "Me.Descriptionm.Height" or Me.Memo.Height
Everything works properly.
I think it's because I have to write the code in a way so that it's applied to each "detail" iteration. I am not sure how.


The other problem is that the Memo and Description field are both set to "Cangrow" yes.
So that I know big they get.
Let's say Memo is bigger than description. I will want to set Description at the same size as Memo.
But I can't, because "Cangrow" is set as yes. And it does not look like I can change this setting from VBA...

Please help, it's a bit hard to understand, but I have been stuck for a long time on this one.

I am doing all of this to have all the solid lines around the fields sized the same. Because if I enable the cangrow option, i will a nice box around each field, but each one of them is different size... so it's looks a bit weird for a "table" type report.

Thanks for your help
