VB 2008 .suo File Needs To Be Changed/recreated Because A Path Has Changed. All Other Files Are OK
May 5, 2012
I changed my Username on my computer from i.e. "xxxxxx x xxxxx" to "Dennis"
VB 2008 during a compile gave me the following error: Error reading icon 'C:Usersxxxxxx x xxxxxAppDataRoamingMicrosoftVBExpress9.0VSProjectApplication.ico' -- The system cannot find the path specified.
The file "VSProjectApplication.ico" is in 'C:UsersDennisAppDataRoamingMicrosoftVBExpress9.0'
Somewhere in the VB2008 "configuration" files I believe that I need to manually change the old path to the new path.
I found the old path in the ".suo" file. The ".suo" file is not a text file. How can I edit the .suo file, save it so that it will work?

I have a ClickOnce app that has been working fine for a couple months, until a day or two back some internal politics borked the server. The result of this was that the path for ClickOnce during install changed just slightly at one intermediate level. It used to have /is/ in the path, and the is has changed to something else. I changed everything I could find, including recreating the whole target directory in IIS on the server. However, when I publish, though the link is correct, installation is failing. The log shows that, after checking and installing some prerequisites, the installation is attempting to go back to that /is/ path to find the app for installation.
Can anybody suggest where that invalid path is located? I have gone through every property I can find in Project|Properties, and they are correct. I have looked in App.config, and that is correct. Where else should I be looking?

on my Form I have a DataViewGrid and some textboxes with a save button (they are filled with additional data of the selected row).Save is disabled first, when I change something in the textboxes the save button is enabled.When the user changes a gow in the grid, I want to ask before changing the grid row, if he wants to save (if the button is enabled).I am using RowEnter but this is too late, then the selected row already changed (and my textboxes already got new data)...What event can I use to ask if I should save stuff before the user changes a row?Something like BeforeRowChanging with a chance to cancel changing the row?

Is it possible to geht the date, when a xml-file last time was changed. I mean the date, which you can see, if you right-click the file and click properties.

I am programming something which involves certain files changing every second. Now, if the files are not changed for, say, 10 seconds it means that some error has occured somewhere, externally. So, I want the user to know about it. How can I implement this?
Sorry cant add comments due to some problem.
@Jeremy - Very small. Precisely, It wont exceed 10-15 characters.

I have written a Type Converter for a TrackBar. I was wondering if there is any way to get the value being changed in the Dropdown so I can update the PropertyGrid item value dynamically instead of just at the end?Here is the Type Converter code:
Imports System.Windows.Forms.Design
Public Class Slider
Private editorService As IWindowsFormsEditorService
Private m_Value As Integer

I'm using FileSystemWatcher to monitor a file on a windows server which links into a news ticker on our desktops. The ticker watches the file and updates accordingly. I've successfully got the ticker to watch for a creation and deletion which is great but the changed function doesn't seem to trigger. Out of interest, I tried this function on the network drive AND a local disk with the same results.
I've upped the buffer but I can't see what else I can do to change it! In the short term, we can probably live with just deleting and recreating the file with any changes that are required, but it would be nice if the ticker would just watch for file changes.

When my app closes, perform a checksum, digital signature, whatever on a data file, and save that in a text file.
When my app opens again, perform that same process on the file, and see if the new checksum matches the saved one, in order to determine if the file has been changed outside the application.

I have implemented the filestream feature of SQL Server 2008 in a VB.Net application. I can insert files, and then retrieve/view them just fine. However, I have huge problems trying to update a file. Eg. The user selects a file from the grid which I execute via process.start. If that file is a .txt file, the user may choose to edit it. In case that happens, I need to save the changed file back to the database. So far I have failed to do that.
What I do, is take the retrieved file, copy it (cause i got some errors about it being used), and then Process.Start it. After that, via .NET filestream, I convert the file to bytes and try to update the record. SQL Profiler and a manual SELECT on the varbinary(max) column tell me that the file is updated properly, but the very next try to retrieve it I get an unchanged file.
After that I also tried to update the file by changing its File-System Version, but the file still wouldn't seem to update. Does Anyone have a code sample of how I can achieve this operation? Like 500 sites on the internet have examples of how to Insert And Retrieve the file, but not a single example on how to update. This is how my second attempt of trying to update the file via the filesystem looks like. The code for inserting/retrieving is very similar and it works properly. [Code]

I have 22 text boxes that have to be checked to see if the value has changed. I am using the TextChanged Event handler to do this thus:
Private Sub TextStringChanged(ByVal sender As System.Object, ByVal e As System.EventArgs)
DataChanged = True
RemoveHandler ........
[code]....
The Handler would be added after the data had been loaded. The question is:Is there another way of checking for text changes without having to add and remove 22 handlers.

I am having a problem catching the event that happens when a user selects a value from a combobox. What I was using was ValueMemberChanged, but because I am populating the combobox in code during runtime using SQL and a dataadapter and dataset, this also executes the ValueMemberChanged event, so that makes it difficult for me to know when the user actually changed the value.

Ok, so I am writing a program (you can check it out at and want to change the inputboxes to match the main form. Now, I know I could use additional forms instead, but I would prefer no to, as I would have to basically start over. So, I need to be able to change the backcolor and forecolor of the inputboxes (and msgboxes would be nice too). I am using 2008, and look forward to getting this figured out. Note: the website does not contain the code, but a published version of the program.

I datagridview and I populate it using a bindingsource. I have the following code in the bindingsources PositionChanged event and it works as I want it to except when I filter the bindingsource.
Private Sub ProductBindingSource_PositionChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ProductBindingSource.PositionChanged
If (Me.ProductBindingSource.Current IsNot Nothing) Then
Dim dr As DataRow = CType(Me.ProductBindingSource.Current, DataRowView).Row
Dim ProductId As Long = CLng(dr.Item(2).ToString)
Dim ResultId As Integer = CInt(dr.Item(0).ToString)
GetReport2(ProductId, ResultId)
End If
End Sub
The scenario is when I click on a row in my datagridview the bindingsources positionchanged event fires and I load a crystal report. Problem is when I filter the bindingsource, even though the first item in the grid is now different the incorrect report is displayed because the bindingsources position hasn't changed.

I have a normal form (FormBorderStyle = Sizeable). When the user maximizes the form, the form's border should disappear and fully cover the screen. Like so:
vb
Private Sub frmVideo_SizeChanged(ByVal sender As Object,
ByVal e As System.EventArgs) Handles Me.SizeChanged
If Me.WindowState = FormWindowState.Maximized Then
'Remove border
Me.FormBorderStyle = Windows.Forms.FormBorderStyle.None
'Bring to front
Me.TopMost = True
End If
End Sub
Problem is, when the form gets maximized and border changed to None, the form doesn't cover the whole screen. The form gets the same height as when it is maximized with a titlebar on top. So, the form is about 20 pixels too short, leaving most of the Windows taskbar uncovered. So, apparently, if the FormBorderStyle changes after the form has maximized, the change in size is not corrected. How do I change a form's size when it's maximized or how do I change the FormBorderStyle before maximization is finished?

Ive got a datagridview, which the user can put in to 'edit' mode by double clicking. If they then make changes but click to another row, I want to msg asking if they are sure they want to discard then changes. If they say No I want to stop the selection change from being made.
Private Sub DataGridView1_SelectionChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles DataGridView1.SelectionChanged

I am working on a way to determine if the lines of a RichTextBox have changed.I currently use this
Dim newhash As Integer = Me.Text.GetHashCode
If newhash <> Me._prevhash Then
Me._prevhash = newhash
Me._lines = MyBase.Lines
[code]....
But this method has a bad issue: The text property takes a while to "load up" plus getting its hash code adds to it. This code runs every time the Lines are needed (it is a property). So this
For i As Integer = 0 To Lines.Count - 1
Dim line As String = Lines(i)
Next
Takes ages to complete, because for every line it checks if the lines have changed.I am trying to evade using MyBase.Lines too much, since that REALLY takes ages to load.
- I can not use the modified property since it is unreliable (set to true if only a text color changes)
- Can't use the RTF since it changes without the text changing (coloring) and the hash code is slow as well.
- Can't use the TextChanged event, since it is sent after the SelectionChanged event (for some reason)

I've got an issue with an Access97 replicated database that I'm writing a small monitoring app for. I've got FSW's to track changes to the necessary files, but am having some issue in enumerating exactly what has changed in some instances, specifically when attributes may have changed. I'm using a similar strategy to track this as I did for changes in size. I've got a Private class variable for the size of each file and a local method variable and compare the two, when different, update the class variable for the next comparison.

I have written a multithreaded crawler and the process is simply creating threads and having them access a list of urls to crawl. They then access the urls and parse the html content. All this seems to work fine. Now when I need to write to tables in a database is when I experience issues. I have 2 declared arraylists that will contain the content each thread parse. The first arraylist is simply the rss feed links and the other arraylist contains the different posts. I then use a for each loop to iterate one while sequentially incrementing the other and writing to the database. My problem is that each time a new thread accesses one of the lists the content is changed and this affects the iteration. I tried using nested loops but it did not work before and this works fine using a single thread.
Here is my
SyncLock dlock
For Each rsslink As String In finallinks
postlink = finalposts.Item(i)
[CODE]...
Finallinks and finalposts are the two arraylists. I did not include the rest of the code which shows the threads working but this is the essential part where my error occurs which is basically here postlink = finalposts.Item(i) i = i + 1
ERROR: index was out of range. Must be non-negative and less than the size of the collection. Parameter name:index
I tried copying it to a new list but dosent work.

How would I execute the above statement? When multiple dropdownlist's are handled in the same sub, how do you tell which one is actually calling the sub? The post by atconway was helpful in guiding me in a direction, but I dont understand the whole concept enough to dive into the msdn library... I would probably spend all my next 7 hours today reviewing it and still not get much further :-P

I use datasets to hold rows of vendor data and case data and such.
I would like to be able to regularly refresh the rows in these datasets that have been changed by other users touching this same database.
In the app we update like this:
_adapter.Update(_casetable)
That looks through the dataset for rows I've changed and calls the UPDATE sprocs.
Let's say I know that case # 12345 has been changed. How would I cause a refresh of the dataset for that case - getting new data from the DB?
