VS 2010 Filestream.position Lands In Wrong Spot
May 26, 2011
I am trying to read a file and note the last position in the file. The next time I look at it, I want to pick up where I left off. What I'm finding is that sometimes when it comes back to the file it is 2 characters further in than it should be. The code I am using is:
Private Sub Read_Log(ByVal skip As Boolean, ByVal recursive As Boolean)
Dim logfilestream As FileStream
Dim logreader As StreamReader
[Code]....
I'm thinking about backing up to check previous characters - but I'd rather not hack over the problem if there is an actual fix to it.

making a WCF service before or do know anything about them, so this should be pretty simple. I have to get this "program" to take an excel file from a folder, and send it to this service but I keep getting this very specific error message:
The remote server returned an unexpected response: (400) Bad Request.
Probably one of the most specific error messages I have come across in my days. This is my code for the program, and what I have as his "service reference".

The goal is to write data to a SQL Server 2008 FILESTREAM file using VB.Net. An "Access Denied" message occurs when creating a FileStream object in the code(see red underlined code below). SQL Server 2008 is configured to "Allow remote clients to have streaming access to FILESTREM data" along with "Enable FILESTREAM for Transaction-SQL access"... What configuration setting is missing and causing the "Access Denied" message? Figure 1.) Code used to stream data to SQL Server managed file

I'd like to know if it's possible to create an .exe file "on the spot."Meaning, somebody enters information...Say, a password field,and they enter, say, "1234".Then they click "Compile". It builds an exe file out of Visual Basic (It takes 2 files, the orm1.Designer.vb and Form1.vb that were just created with the string "Dim password as string = "1234" "), then it compiles it into an .exe.

I've got a DataGridview I want to remove columns from as it greatly increases performance when I format the DGV. The first time I remove columns in a loop (using the removeat) property, everythings fine. But when I try to remove more columns in another loop, it appears to remove the wrong columns and displays the wrong data. In other words, it displays the wrong data and headers; and the columns it does show has headers and cells that don't match.

When I use the code
Public Class Form1
Private Declare Function GetAsyncKeyState Lib "user32" (ByVal vKey As Integer) As Integer
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[Code] .....
I get an error saying that the cursor format may be wrong. It is a .cur which is the standard for cursors. How to rewrite this so when GetAsyncKeyState(1) then the computers cursor will change to the currentcursor.

my code is as below.
vb
Dim RegKey As RegistryKey = Registry.LocalMachine RegKey = RegKey.OpenSubKey("SOFTWAREMicrosoftWindowsCurrentVersionAuthenticationLogonUIBackground", True) RegKey.SetValue("OEMBackground", "00000000") RegKey.Close()
If I output the contents of it on a msgbox, things are fine, but when I go to regedit, the change doesn't happen where it should as it actually happens in another registry key located at
HKEY_LOCAL_MACHINESOFTWAREWow6432NodeMicrosoftWindowsCurrentVersionAuthenticationLogonUIBac
k ground which I guess happens since I am on windows 7 64 bit, but I don't want that to happen as doing that doesn't change anything. The key I'm trying to change makes changing the default logon screen possible in Win7, but it's not working like this since the wrong key is being modified.

Could it so when the timer is ticking that it will move the mouse over to a certain color and click the spot once? For example if it finds on the screen a "green" spot or "hue:79 ; Sat:224" that it will click the spot once?

I'm trying to copy an array starting at a specific based on the number of variables I have. I have the program give me the number of variables. What I need is to copy the original array, UnsortedArray, start at the index of var + 1. I have tried the Array.Copy and Array.CopyTo, but I get the error that my new array, UnsortedNumArray, is used before it has a value.I know I've mostly overlooked something. Could you please point me in the right direction? [code]

TI have a picturebox on top of another picturebox, like a smaller square perfectly in the middle of a lil bigger square picturebox, if you click on the smaller one inside the slightly bigger one, it checks to see what the color is of the picturebox "under.It", or the Picturebox thats bigger than it, and is like sourounding the smaller one in the middle of it... If when you click the small one, and the BG Color of the one that's under it is Black, change it to white, "my forms bg color is also black"....so the highlighted pictureboxes will seem more like they get highlighted, ya know...
Here's the code, after you've looked at those pictures, you can probably imagine what I want this code to do, and it's really Guiness really, because when I program in VB.NET, and before I go to YouTube to teach others how to do different things with VB.NET,I like to make sure that my program is very simple, but very effective, and does the job.When I click two pictureboxes, and when my app knows that I have clicked 2 of em, which I had no problem being able to do, I want the FIRST PictureBox To Switch With The Second One That Gets Clicked, It's CHESS....It Seems So Damn SImple, BUT I'M STUCK AGAIN, AND I WANT TO MAKE A CHESS BOARD IN VB.NET.

I have kind of a wierd situation: To start out, I have a list of strings. Then the user will give input and add list items. I have this^ part done. What I need to do now is the following: There are two buttons; button1 and button2 There is also something else that I still need to decide on (maybe a dropdown menu) I want button1.click to show openfiledialogue1, the user will pick a text file from their computer (I also need to know how to make the only file they can select text files) and then save the file's text to a string. The text will be made up of multiple lines of an unknown number.

there's a list-box with items, and say you want to modify an item in the middle of the list. You select that item and click "Modify" button and a new form appears with the previously selected item data from first form ready to be modified in a text-box. After modifying and clicking Ok the second form suppose to return that modified string to the first form and insert the modified string into the same spot instead of the originally selected item, so it looks like it was edited to the user.

I'm trying to set a new cursor position but I get this error:
A call to PInvoke function 'mon! WindowsApplication1.Form1::SetCursorPos' has unbalanced the stack. This is likely because the managed PInvoke signature does not match the unmanaged target signature. Check that the calling convention and parameters of the PInvoke signature match the target unmanaged signature.
Here is the code:
Declare Function SetCursorPos Lib "user32" _
(ByVal x As Long, ByVal y As Long) As Long
SetCursorPos(457, 603)
It used to work when I used VS 08 but now I use VS 10 and this problem has started to appear.

I know how to get the cursor position but how do I add a character to that position. Like I want to have a button that adds a specific character at the position of the cursor.
I don't see any richtextbox properties that allow me to add anything at the cursor position.
If TypeOf Me.ActiveControl Is RichTextBox Then
Me.ActiveControl.SelectedText = Chr(176)
End If
