MDI Parent Client Size Calculates Incorrectly?
May 4, 2010
[URL]...The link above is a thread showing the application I'm working on. (2008 Pro)I have since created an MDI Parent form which holds my 16 camera forms. What I am having trouble with is dividing the MDIParent's Width and Height by 4, to display 4 equal height/width camera forms within it.
I've tried all the available properties (Rectangle, ClientArea, etc) and none seem to calculate correctly.Using Me.Width and Me.Height ALMOST worked, but again, it was about an inch too skinny and short.
What do I need to do in order to retrieve the exact size of the MDIParent's Client Area?

I need my window to be an exact size. Isn't it possible to specify the exact size of the client area (the drawable part) as opposed to the entire form including the menu bars etc?

I want a set of child forms to keep their relative sizes and locations to their parent form when parent form is resized. So if one child form is opened and covers the lower right quadrant.. it will remain a quadrant for whatever resize is done on parent form.

I like to compress the xmldata before the data is provided to the client as an excel file. I am trying to compress and deliver it as a .zip file. its not working Here's my code below. I tried compressing it, converting it to bytes etc etc. The issue with below code is, the XSL transformation is not happening properly and the output excel file is raw xml with some .net exception at the end. (that's what I see on the .xls file that's downloaded at the end) Before I started working on compression my below code was working fine that gives properly formatted excel file from the xml input. the excel file is so nice you can't even tell it was from XML.

We are creating a Who wants to be a millionaire style game in VB. Our server is pulling information such as questions and answers from a Access Database and sending them to the contestants (Clients). All transfer of information is directly from the server to each client.

Today this is displaying as 161432. However, according to a user, the arabic text should be in the middle with the year 1432 at the end. However, when you highlight the text, it highlights back to front.

Basically, what I am trying to do is scale part of an image. In VB6 the Scaling version of the BITBLT api worked fine, however in .NET's Drawimage version of it works okay, until a different destination size is specified.url...The red is from the next tile on the source image. and the bottom is missing one row of pixels.I have also screened this, and counted that the left side isn't properly doubled and the very first column of pixels is in 1x1 squares instead of 2x2 like the rest of the image.I don't get why it's obtaining outside the range I set, so here is my code incase it helps, note that you'll need to define a blocks array:[code]

See graphic.Is this right? (Top is what I am seeing, bottom is what I expected to see.) Do I just really not understand Arabic culture and ways, or is there something wrong here?

I am working on a website at the moment which is displaying a strange bug with generated word documents. The site has a feature on it which allows the user to download a word document containing information related to their visit. This file is generated via some vb.net code and takes an xml template of the final document and inserts the relevant content required.
The strange behaviour is that on some machines the .doc file generated displays fine and on others it displays as XML when opened in Word. Both behaviours have been seen in the same version of Office (2003) but on seperate machines. My question is really whether the error lies with the set up of word on the individual machines, or whether there is an error in the code.
The code to create the file and download it is as follows:
Response.Clear()
Response.ClearHeaders()
Response.AddHeader("content-disposition", "inline; filename=MyNewFile")
Response.ContentType = "application/msword"

I have a temp dataset (ds) that I load with data from a filtered dataset. I run this in a loop essentially populating the temp dataset with select records from the main dataset. I then merge the temp dataset back to the main dataset (dsSpecifics). The issue I am running into is that the records are loaded into the temp dataset in the way they were merged. record 1 is at row 0, record 2 is at row 1 and so on. When I merge the ds back to dsSpecifics, they load out of order but in a predictable way. Here is a snipit of the code:
myAircraft.Reset()
While myAircraft.MoveNext()
Me.TblAircraftSpecificTableAdapter.FillBy(Me.DsSpecifics.tblAircraftSpecific, CInt(myAircraft.Key.ToString))
[Code].....
It seems that after the final merge, the merge starts with the last record of ds and and then rolls over to record position 0.

I have 2 buttons, named: 'Select item 1' and 'Select item2' to these buttons I have added images. how? when the form loads I execute this
Private Sub LoadButtonImages()
btnCompare1.Image = My.Resources.close1
btnCompare1.ImageAlign = ContentAlignment.MiddleLeft
[Code]....
when I test the program on my friend's pc it gives an error and does not display the image. ( and yes I already tried putting the executable in exactly the same folder as it is on my pc WITH the image folder.. )
so is there any way to use the first method of loading the images and ensuring the size is correctly? Ive added 2 screenshots to show you what I mean by incorrect size..

I've nearly finished my latest project (VB 2008 Express Edition) I built the project and ran the .exe from inRelease and it appears and works exactly as it did in Visual Basic
When I carry this .exe to any other computer, it displays differently. The biggest difference is the font size in labels (grows on other machines) and the size of the tabcontrol is a bit larger on other machines. see the links below for comparison (coding machine vs other machine) [URL]
note that both machines were set at the same screen resolution, both were using the default Windows XP "Theme" and display fonts appear to be set the same on both machines. I've tried this on about 3 other XP machines with the same result (only looks correct on the machine I coded on)
I've specifically used Microsoft Sans Serif font, size 8 (VB seems to display this as 8.25pt in the properties window) I have also tried making all labels "UseCompatibleTextRendering" both true and false with the same result. Perhaps something on the original (programming) machine is different that is throwing this off? Am I missing a step when building this project? If other encounter this problem often, what steps do you take (when programming) to avoid this and allow the form(s) to display correct regardless of the user's settings?
Edit: One difference can be found in (Right Click on Desktop -> Properties -> Settings Tab -> Advanced Button) the DPI Setting on the coding machine is Normal Size (96 DPI) The DPI on the other computers is Large Size (120 DPI)
The application will be used by roughly 100 folks on various systems (some Windows ME, most XP). How can I prevent things from going crazy with different user settings?

I am working in VB.net 2008. I have a Window application that will be used to eliminate a lot of manual copy and paste activates from one work sheet to anther. Workbook 1 (wbMatrix)Never has the same layout twice. The destination Workbook2(wbTemplateSAS)has a defined layout that remains constant. To collect the copy ranges the user pouplates the text box on the form. Only the textbox that need popualted. There are 16 total. These textbox values are then concantianted to create the range. This process is intiated with button click.
When itinated the copy and paste works but not as expected. Cell.text range paste correctly In A9, OEC range paste correctly in P9. After that it skips the next colume as it should. Then in colume R9 the error starts the a paste of the range A10:B10 form wbMatrix is pouplated in R9:S9 Then It paste accoring to the application T9. Then in U9:X9 it paste date for wbMatrix A10:D10. It paste correctly again in Z9. it has the same error agiain till the next Range. It then paste correctly in 9AD. This should be the last paste that have values entered in the textbox to create the range. But it does not finish it paste the balnce of the cells form wbMartix on wbTempateSAS.
To sumerize above
wbMatrix Paste to wbTemplateSAS
First Row =10
Last Row = 158

I have an application that I'm deploying using Clickonce that includes the Report Viewer. On my development machine, the reports work perfectly. However, on client machines, the reports are having printing problems. On some machines, the first print sends a 2 page document to a printer that displays an error message. On those machines, printing the second time is successful. On other machines, the first attempt doesn't get sent to the printer at all. Subsequent attempts work just fine.This happens each time a form with the report viewer is displayed - the user must print twice to get a correct print-out of the report.
NOTE: if I create a network shortcut to the application for a user that has NOT installed the Clickonce app, they are able to print from the Reportviewer without any issues. However, once they install the Clickonce app, the Reportviewer is "broken" (for lack of a better word) and won't print on the first attempt in ANY application.I know that I probably need to do something in my Publish settings to force the correct, newer version of the Reportviewer to be installed, but I can't figure out what that is.
I have Microsoft Visual Studio 2005 Reportviewer selected in the Prerequisites list, and there are 4 Reportviewer files in the Application Files list:Microsoft.ReportViewer.Common.dll - Prerequisite (Auto)Microsoft.ReportViewer.ProcessingObjectModel.dll - Prerequisite (Auto)Microsoft.ReportViewer.WinForms.dll - Prerequisite (Auto)Microsoft.ReportViewer.WinForms.xml - Exclude (Auto)?

I'm exporting a datagridview to excel. The first column is a Date (not DateTime) which appears like '2/15/2011'. After exporting the datagridview to excel it appears in excel as '2/15/2011 0:00', furthermore the first 68 rows in excel appear as '6/14/1898 12:00:00 AM'. Where is the time coming from? The column type in the database is date. I've attempted to edit the cell style of the datagridview column to date. I've attempted to figure out how to pre-program the formatting in excel, but it's not working either.

i recently received a new work pc and have installed visual studio 2010 premium on it. this was installed on my old machine as well, the only differece between the two PCs being my old one was 32bit and the new one is 64bit.With that said, when i create a windows form project and drop a control on a form, double click that control, the default event code is created for me.It is missing the "ByVal" portion of the code. Using a textbox as an example, below is the code it generates. Is there a setting that I'm just missing and need to turn on? I've been using visual studio since version 2005 and i've never seen this before.
Private Sub TextBox1_TextChanged(sender As System.Object, e As System.EventArgs) Handles TextBox1.TextChanged
End Sub

This is a challenging one that got me stumped while I was coding today. Suppose I am running the Sub Test1() and Test2() and would like to print out the value of the Shadows method of the instance of the object I am passing in to TestCall() (see below - it is clearer) using the following restrictions:
Can't change the contents of Class A, B, and C
Can't change Sub Test1() and Sub Test2()
TestCall() can't have an if, select case etc. statement that tries to figure out the type

I have a main form, and some sub forms, and each sub form can have some sub forms. When I have multiple sub forms open, and I try to get data from the parent form, it returns the data from the wrong parent form.For example I have two instances of Mainform.subform running. If I do something like this in a child form of one instance of the subform. It returns data from the other subform.
dim l = Mainform.subform.listofdata
Edit:I am using visual Studio 2008. Winforms, form designed using designer. In my mainform I am doing this
Protected Friend frmMain as Mainform
frmmain = new mainform
In frmMain I am doing this
Protected Friend frmsub as new Subform'
frmsub = new subform

I had a strange problem editing a class in the property grid whereby the property grid would refresh incorrectly.I managed to reduce the problem down to a class with just two properties. I've included the code at the end to ease explanation.It basically boils down to a class with two properties. The first of which is expandable (a font)The class itself is expandable and also implements the CreateInstance method in the type converter.To see the problem, expand the font, edit, say 'Bold', and tab away. Two problems happen:
(1) The second property jumps up and ends up in the expanded font property.
(2) The '-' sign of the expanded font changes to a '+'.
The problem goes away by attaching ResfreshProperties(RefreshProperties.All) to the class. That's great, but I'd like to understand how it fixed the problem. I've had a look in reflector and can't find any examples of RefreshProperties being attached at the class level.

Now all went well about from using the structure correctly. The working of the structure was perfect. How ever i missed Two important issues. The structure needed a fixed size of 10 items (9 in programming terms starting from 0) And also out of the 5 items allowed to be chosen as one of the member types for the structure a limit of 5 items of that particular type.

I am creating a form that calculates QB Ratings but its not coming out right. The formula is found here
My code:
Dim a, b, c, d As Integer
a = (Comp.Text / Att.Text * 100 - 30) / 20
b = (Yards.Text / Att.Text - 3) * 0.25
c = Tds.Text / Att.Text * 20
d = 2.375 - (Int.Text / Att.Text * 25)
Rating.Text = "QB Rating:" & ((a + b + c + d) / 6) * 100
Number set 1:
22 complete
36 Attempt
2 touchdowns
0 Interceptions
229 yards
It should come out 98.0 but comes out 100
Number set 2:
16 complete
37 Attempt
0 touchdowns
3 Interceptions
205 yards
It should come out 27.4 but comes out 33.3
