Color.ToArgb Relation Between 5046311 And 14221235?

Sep 2, 2010

the form backcolor is 14221235 , but when i set the customcolor in colordialog to equal the form backcolor, it sets it to 5046311 !!! what is the problem?the reason i am turning it into a string is because i will feed it into a string which has "32498239, 234234234, 23423234, 32234432432, 423324234"then i take this string and put it in customcolors like this. btw this piece of code works fine:

Dim numberStrings = My.Settings.mytext1.Split(","c).Select(Function(x) x.Trim())
ColorDialog1.CustomColors = numberStrings.Select(Function(x) CInt(x)).ToArray()

Get Relation Between 2 Databases?

Jun 7, 2011

I have two dataset , each with with table . each datasets is connected to a separate dataadapter to get data from sql server database file (two different tables SQLtableOrders & SQLtableCustomerA))

datasetOrders.Tables("Orders") >>> the first column "orderID" is a primary unique key. Its structure is details below :
OrderID----OrderName----OrderCost--------Date
1----------A---------------54------------11/11/2010

[Code].....

note that I had already made this by getting the data by SQL Statement "Select SQLtableOrders.* , SQLtableCustomerA.orderID FROM SQLtableOrders, SQLtableCustomerA WHERE SQLtableOrders.orderID = SQLtableCustomerA.orderID" It is really working fine , but the problem that it takes time to get data from the SQL server each time I disply orders. I already have the datasetOrders.Tables("Orders") data on the client PC , I need only to make the client PC extract which orders are assinged to a ceratin customers. I can do it by For... Next , but I guess it will take time , specially if "orders" data contains many data .

.net - EF - Only Removes Relation When Hit By Breakpoint?

Jun 7, 2012

<HttpPost()>
Function Edit(<Bind(Prefix:="Article")> ByVal Article As FormCollection, Optional ByVal DepartementID As Integer = 0, Optional ByVal LeverancierID As Integer = 0) As ActionResult ', ByVal ReferenceSupplierID As Integer
' Dim Art As Article = ArticleService.GetArticleById(Article.ArticleID)
Dim _toUpdateArt As Article = ArticleService.GetArticleById(Article(0))
UpdateModel(_toUpdateArt, Article)

[Code]...

toUpdateArt.Departement = Nothing and _toUpdateArt.Supplier = Nothing is to remove the optional relationship.But it only works when i debug it and sometimes after several loops of the command, before the relation is actually removed and it's stored in the database.When there isn't a breakpoint on the "function", the Relationship will never be nulled.Does anyone has an explanation for this and how to fix this?

DB/Reporting :: Relation DB Design?

Apr 21, 2010

I am designing a system for our sales team to enter their sales expenses. I have designed an input form and need some advise on what exactly I should store in the expenses table VS lookup from the employee table.

First, the form has a text box where the user must enter their EmployeeID. Management asked for a text box VS a combo box because they do not want users looking at each others expenses. The form has a search feature where by after you enter your employee number, it will look for an existing expense ticket first before allowing you to create a new one. Anyway, here are some of the decisions I have to make.

When the user enters their employee number, I would like to display their employee name. The EmployeeID is saved in the Expense table but should I also store the name in the expsense table? If I do save it, it's duplication of data, if I do not, I have to look it up each time the record is loaded. But is there a point storing the name long term? Does this qualify as related data? If I was to perform some reporting, could this cause a problem if an employee changes their name etc.

The expense data is spread over 2 tables, the first for the header details including employeeID, expense date and Expense ID etc. The second table contains the expense lines information. Amount, customer, category etc. My next question is when the employee chooses an expense category, there is an associated general Ledger code with that category. Again, the expense category data is stored in a table. When the user chooses the expense category, should I store the categoryID or store the values associated with the ID (GLAcct, CategoryDescription etc.) Does this qualify as related data or should lookup values always be duplicated in the master table? It is possible that over time, the GL accounts associated with the Expense categories could change. So for accuracy purposes, should they be stored in the expense lines table?

Get The Angle Of A Line In Relation To The X Axis?

Apr 18, 2011

i am trying to get the angle of a line in relation to the x axis. The line is being drawn in a picturebox. So its the Upper right quadrant of the cartesian plane ... but its flipped over the x axis.im using this code

a=pt(1).x
b=pt(1).y
c=pt(2).x
d=pt(2).y

z=math.atan2((c-a),(d-b))*(180/math.pi)

The issue is that the line im drawing is almost parallel to the x axis but its returning a value of roughly 90 degrees .It seems like it is giving me the angle in relation to the y axis, but not being super good at the math myself im not exactly sure what to change here.

Get A ContextMenuStrip In Relation To The Parent Control It's Under?

Dec 30, 2009

I've made a ContextMenuStrip to use in my program to change the image in a picture box. However, it's used with multiple picture boxes which each need to have their own changed. What I want to do is make my command change only that picture box leaving the others as they were before. An example, if this were a plausible code.

Private Sub TestToolStripMenuItem_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles TestToolStripMenuItem.Click
Self(aka the control that currently has the menu open).Image = My.Resources.Picture

Get The Form Position In Relation To The Screen?

Apr 16, 2011

I have this code working fine , it takes pictures of the correct size and correct file name , however , all the pictures it takes are in the top left corner of the screen , rather than where i have the form to. FYI the picture box in the middle has no picture in it , and is transparent , i want to save a bitmap of the contents of the picturebox ( a user defined size of the screen). The picture box and button are docked so that the form scales properly when being resized.

I am using Linq-to-SQL so unforunately it doesn't used nested objects, but it still knows the relation.

C# - Relation Table In DataSet Always Returns 0 Rows

Jul 19, 2010

I have created a strongly typed dataset in the VS 2005 Dataset Designer. There are two tables that relates to each other in a one to many relationship: Claim and ClaimDetail. The designer automatically creates a function GetClaimDetailRows which returns all ClaimDetailRows for a ClaimRow. Why is this Array's length always 0? Because ClaimDetail contains more than 40 Million rows, i did'nt fill it before i call GetClaimDetailRows but had configured it's selectcommand that it takes a parameter idData to fill only the related records. But that seems not to work because the ClaimDetail-Datatable is empty.

The automatically generated function in the ClaimRow-Class which returns all related ClaimDetailRows:
Public Function GetClaimDetailRows() As ClaimDetailRow()
If (Me.Table.ChildRelations("Claim_ClaimDetail") Is Nothing) Then
Return New ClaimDetailRow(-1) {}
Else
Return CType(MyBase.GetChildRows(Me.Table.ChildRelations("Claim_ClaimDetail")),ClaimDetailRow())
End If
End Function

When debugging I see that it jumps into the else block but returns 0 rows. Do I have to fill the Claimdetail-Datatable first(ClearBeforeFill=True) for each Claim? But then I don't need to use this function anymore. I now fill the Datatable(ClearBeforeFill=True)before i call the Child-function and it works. But I don't understand why it could not throw an exception(optionally) when I try to acess a child-relation without having that datatable being filled(at least with 0 rows). Instead of that it returns 0 rows what can be correct or incorrect and is difficult to detect.

VS 2008 Update Parent & Child With Relation

Aug 7, 2011

I am going to ask a dumb question. I want to update my tables (two). There is a one to many relation between them. I know how to update when only one table is update, but how do i update when there is many on the other side. My problem is that , if one of the records on the many should become redundant, how would i delete it in the update process. If only the content changes , it is not a problem, i know the data just gets written back to the tables, but if one of the child records is not delete, how would it work I need some clue on the SQL statement using OLEDB

VS 2010 Printer Co-ordinates In Relation To Margins

May 22, 2012

If I use the following code to draw a rectange, do the values inserted into 'fromleft' & 'fromtop' set a co-ordinate from the top/left corner of the paper or from the top/left corner of the margins.

Dim R As Rectangle
Dim across As Integer = 5
Dim down As Integer = 13

[Code]....

The reason I am asking this question is because I am trying to print labels so the position of the labels on the sheet are fixed. When the printer is set to papersize = letter the first label is in the correct position but when I change it to A4 the first label has moved 4mm to the right. With the margins set to 0 I still cant get it justified correctly. The printer is obviosly capable of printing 4mm from the left because it does so when set to 'letter'. Can't use letter because I need the extra length of A4 for the bottom row of labels.

Parent Child Relation In Gridview (windows Application)?

I am developing a small windows application(vb.net).In that i want to have parent child relations in a gridview control. There are lots of examples available on this, but they are using two gridviews for that, but in my case i want the relation to be displayed in a single gridview control itself. When they click the + sign immediate row should populate child rows with it's own header(ie child rows has it's own header which is different from parent header). In my case parent row has 2 columns and child row has 4 columns.

This ensures constraints are not created.That solved the problem. However, I want to know if this is the correct solution. It is really difficult to troubleshoot as I cannot reproduce the error. The database is accessed through the network. it could be the network was down at the time so the child records where not inserted hence the error.

IDE :: Design A ContextMenuStrip In A Designer Without A Relation To A Specific Form Or UserControl Class?

Oct 16, 2011

in VS 2008, is there a way to design a ContextMenuStrip in a designer without a relation to a specific Form or UserControl class? For example,if you need the same ContextMenuStrip in Form1, Form2 and Form3, in which of them am I to design the ContextMenuStrip? Do I have to add a "pseudo-Form" to the project that contains my shared ContextMenuStrips and create only one instance of that Form, or is there another way? I consider this a programmatic hack, that's why my question is whether the IDE offers something better.
