I am trying to check if the string starts with certain words before I even add it to my item list, but it doesn't seem to return true even when it should return true.. File I am reading through with my application:
I am working on my application as I am checking ip using with .StartsWith and .EndsWith method. If the ip is equals then it will equals with US. However I have got an error with end of statement expected error using with this line: [code] I have tried to use "And" instead of "&", but I still get the same error.
I have two DataGridViews in one window. The first one displays 2 columns, itemNo and taskWhen I click on a row in this grid, I want to populate the second grid with corresponding material. It is organized so that the itemNo in grid1 is 1, 2, 3, and so on, and so when a row is clicked, I want grid2 to show data that is 1.0, 1.1, 1.2, 2.0, 2.1 and so on. This data is all available in a table that exists within a dataset. However, tableAdapters do not use the .StartsWith function. I am able to get the information from grid1 when it is clicked on using Me.DataGridView1.CurrentRow.Cells(0).Value.ToString but how can I use this to get the data from the table into grid2
In my code I can easily use "where Obj.Feld = String", but using "where Obj.Feld.StartsWith("a")" doesn't work. See the following two functions:
[Code]...
The first function (byFileName) works fine. The second function (LikeFileName) doesn't. Using Startswith I get "Object reference not set to an instance of an object." What am I doing wrong?Database is an array of Objects, a structure consisting of strings
Currently, I have this method to compare two numbers
Private Function ETForGreaterThan(ByVal query As IQueryable(Of T), ByVal propertyValue As Object, ByVal propertyInfo As PropertyInfo) As IQueryable(Of T) Dim e As ParameterExpression = Expression.Parameter(GetType(T), "e")
As you can see, I give it an IQueryable collection and it add a where clause to it, base on a property and a value. Y can construct Lessthan, LessOrEqualThan etc equivalents as System.Linq.Expressions.Expression has this operators predefined.How can I transform this code to do the same with strings? System.Linq.Expressions.Expression don't give me a predefined operator like "contains" or "startwith"?
In this case GDI no longer stands for Graphic Device Interface! I have an MDI form, and the child form loads up with a single panel positioned at a specific spot so that i can have a visual studio styled menu on the left side. The square white area is the panel with the fields in it for the user to enter. The left side is a TreeView with GDI lines drawn around it that dont appear until the menu has been changed. Here's what the menu looks like when its rendered properly:
When the form first loads, you can quickly see the GDI drawings come up (sometimes) then disappear. It flashes pretty quick when you can actually see it, but until you change the menu item to another causing it to redraw, its just... gone.. Looks like this:Here's the setup:I have two labels docked at the top for the large white text with a black background
There's the treeview on the left in a picturebox where the GDI components are drawn, and a panel touching it on the right side, which is sized and anchored on all sides basically keeping it stretched to the size of the window while keeping the top and left side pinned in position so it doesnt move, keep it touching the menu on the left.
Inside the panel is 10 more panels, one panel for each menu item. Each panel is programmatically set to resize to 1024x768 and becomes visible once the menu item for that panel is clicked. The panels are all programmatically top positioned at 0 and left positioned at -1 to hide the left border stroke from having the BorderStyle set to FixedSingle. Moving it to -1 hides only that border within the panel its in.
I have dual monitors, so i began stepping through the code on one monitor with the program running on the other so i could see what its doing with each step. While going through, at one point i see the contents of the TreeView completely vanish, but all the drawn GDI stuff is there. Once i get through everything and finally hit F8 on the very last line when control of the program is given back to me because its now waiting for me to do something, all of a sudden the treeview contents re-appear and the GDI drawings vanish.
I just upgraded a project from VB 2008 to VB 2010. Before, the project did not use LINQ. I have started implementing it. So, I have updated the target framework from 2.0 to 3.5, and added a reference to System.Core, and imported the namespace System.LINQ to the entire project and also imported System.Data.LINQ into the form I'm working with (because it was not available in the list for Imported Namespaces in the references tab).
It's not throwing any errors now, but my IntelliSense is not working for LINQ stuff.
For example... I write this:
[CODE]....................
Then, if I type S. on the next line, the IntelliSense doesn't grab what it should for S (Only get Equals, GetHashCode, GetType, ReferenceEquals, and ToString, instead of the options I should get like Count, First, FirstOrDefault, etc...). If I Type S.First. then its the same thing, no IntelliSense that lists the available fields for S, just the standard options (Equals, GetHashCode, GetType, ReferenceEquals, and ToString). I should be seeing my column names in my table when I type S.FirstOrDefault.
So any ideas what is going on? When I type the code, for example, MessageBox.Show(S.FirstOrDefault.FirstName), it works perfectly. But it doesn't change the casing of the text (so it would read s.firstordefault.firstname) and no intellisense while doing it. But no errors. BTW - Everything works perfectly when creating a NEW VS 2010 application, it's just my projects upgraded from Visual Basic 2008 that have this issue.
I recently got microsoft expression studio and VS 2010..To test out expression, i created a sweet looking UI, and transferred an old program from VS 2008, but the CSV writing function I have written in the '08 doesn't work with my WPF form in '10.
CODE
Private Sub ReadTimer_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ReadTimer.Tick CurrentPosition.Read() CurrentPositionValue.Text = CurrentPosition.Values(0).ToString()

specifically, the error is, "Computer is not a member of My" ....
I'm setting the Image & BackgroundImageLayout properties of a PictureBox programatically, but it's not working. I set the layout to Stretch to fill the picturebox, but the image just displays in it's original size. Here's the code I am using:
MsgBox(ListBox3.Items(i).ToString.ToLower) MsgBox(clientdata.Split(":")(1).Split("|")(1).ToString.ToLower) If ListBox3.Items(i).ToString.ToLower = clientdata.Split(":")(1).Split("|")(1).ToString.ToLower Then else
[code].....
Now the weird part is that it goes to the Else case, while the 2 variables in the If are the same.
I found someone's code that they posted on YouTube for a file exists. Now, with their setup it worked fine, but I am trying to search the ENTIRE computer. Not just the application folder, and I can't seem to get it to work.
[Code]...
Using that code I can search for the specified folder and if the file exists it changes the text. Now this works, but I would like to search everything in My Computer at once.
[code]Well, the first GetPixel works fine, it sets textbox2 to yellow if the pixel is ofund and textbox1 says green. But, the second GetPixel doesn't work. The coordinate are correct and the color is also, but I never receive the msgbox.
my program connect to Access DataBase 2003 ! in my computer every thing be ok !but in other pc my program can not open on show this message :
my OS is 7!my VS version is 2010 and it is my connection string : "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + My.Application.Info.DirectoryPath + "my_db.mdb" where is my problem ?
I have form1 and form2. On form 2 i have 2 combo boxes where the user is asked to make selections. once back on form1 i try to use those selections as part of an if statement but although i should be triggring them it does not. I cannot figure this out. I have set up test variables and msgboxes along the way to test this.
The code excecutes. I have double checked the variables on form 2. They just do not trigger a response that will enter the if statements even though it looks like they should. I have double checked that test1 and test 2 are grabbing the variables from form 2
test1 is "Male" test2 is "10 - 19"
When the code excecutes i never get to the msgbox("Age") line of code. I have also tried taking the spaces out of the strings with no luck as well.
I've got a button in my app's window that I'm trying to click with code but it isn't working. I googled and found out to do this (in an MSDN document I think):
I am serializing and deserializing a class - and sending it around with httplisteners - code looks like this Dim inputstream As Stream = request.InputStream()Deserialize(FSOb, inputstream)With the Deserialize function looking like this (and the Serialize as well - it deals with a memorystream)
Public Sub Deserialize(ByRef FSOb As FSObject, ByRef st As Stream) Dim bf As New BinaryFormatter() FSOb = CType(bf.Deserialize(st), FSObject) End Sub
OK, so my accumulator is now adding and showing properly in the form as a total. However, something is wrong in my if... then statement and it's not throwing it to the 2nd level after reaching the 125.*Edit to show updated with the Do While Loop. Now causing issues with my input error msgbox... *

We had our Crystal Reports report sheets in 2008 working and when we moved to 2010, some of them which their datasources were binded to dataset and datatables are not working.

I generated SQL Server 2008 Database scripts. There are total 80 objects. The script executes successfully from sql server query. But not from .NET. That is I want to create the objects (tables and stored procedures) from there.If the database don't exist already in sql server, it fails. I have included the line
IF NOT EXIST (DATABASE)... CREATE DATABASE DBNAME
But it simply don't work and the process fails while the code perfectly works directly in SQL Server.
Any work around this? Can I run CREATE DATABASE somehow?
All the tooltips in one of my apps stopped working. I checked the component; the settings are all the same as on another app that still works. what would cause tooltips to suddenly turn off?
