I have a simple datagridview that I fill from a mysql database using the latest mysql connector.net.I configured my columns in the datagridview collection and the data displays fine.I don't want the user to edit data directly in the grid so my datagridview is not readonly but all my columns are except the checkbox one. If I set the datagridview readonly I can't check my checkboxes.I added a checkbox column to be able to delete multiple rows easily but I can't uncheck a checkbox.
Let's say I have 3 rows in my datagridview I check line 1 checkbox- I check line 2 checkbox- I uncheck line 1 checkbox- I check line 3 checkbox As soon as I check line 3 checkbox, line 1 checkbox becomes checked "automagically"

I have a VB 2008 program that has a number of forms. When I run the compiled program on a different computer, the form appears different. The relative position of various controls on the form are different. Its as if the controls have been repositioned. Resizing the form does not correct the problem. The only difference between the two machines is the size and resolution of the screens.

I am been working on an a small app that has a Forms.Webbrowser control that navigates to a Adobe Flash program. I have developed the app on Vista 32bit platform and have had no problems. I have sent the app to a couple of people to test out and one is using Vista 64bit and is running into a problem. I know the webbrowser control just uses the underlying base framework of IE. The problem on the 64 bit machine is when the site is navigated to it says that it needs to have Flash installed. When the user goes to Adobe's site it says they need to use a 32bit browser.
As stated on Adobe site here:[URL] the Flash player need to be in a 32 bit browser. What options do I have to be able fix this problem? Is there another control that I can use that would be the same in a 32bit platform and 64bit platform? Besides navigating to the Flash program, the browser also goes to standard web pages.

I'm exporting a table of data to CSV format, e.g.:
"COL1","COL2","COL3"
"1","some text", "£232.00"
"2","some more text", "£111.00"
"3","other text", "£2.00"
The code to export is fairly simple using an ashx handler:

My issue is when Excel tries to open the exported file the character appears before all £ signs, e.g. £232.00 when the value should be £232.00.

I have a bit of a strange problem with MySQL that I've never seen before. Basically, I need to enter the same entry into a table x number of times. The Primary Key is auto increment so there shouldn't be any duplicate value problems. However, it takes the last few columns and seems to clump them all into one value and is using that as a key. The error I'm getting back is:Duplicate entry '80-0--2011-06-16-0-1' for key 'idx_mtind you, there is no field called idx_mt. The primary key field is called just ID. And that 80-0--2011-06-16-0-1 is the last 8 columns or so (which you can see the names of in the cols variable) concatenated, which they obviously shouldn't be doing. Also, the first time the loop runs through, the entry goes through, but the later ones conflict with it. I confirmed that this is the problem by changing one of the last 8 columns to a value based on a loop, and that went through with no problems.
Dim cols As String = ""
Dim msi As System.Globalization.DateTimeFormatInfo = New System.Globalization.DateTimeFormatInfo()

i am working on an application which calls the COM component of a partner's application.Ours is .Net, theirs isn't. I don't know much about COM; I know that the component we're calling is late-bound i.e.obj As Object = CreateObject("THIRDPARTY.ThirdPartyObject")We then call a method on this COM object (Option Strict Off in the head of the VB file):obj.AMethod(ByVal Arg1 As Integer, ByVal Arg2 As Integer, ByVal Arg3 as Boolean)I am a bit nonplussed that even though this call works, this overload doesn't exist in the COM interop .dll that is created if I instead add a reference to the COM server using Add Reference. The only available call to this method that it says is available is AMethod().

I got kind a mystery situation. There's not a lot of code, only few lines but the point is that it only works partially (it saves but does not load).
I tested it with another cmbbox1, which makes it work on seperate cmbboxes but not on either one or onother on their owns.[code..]
I got other cmbBoxes with titles on them loaded from the DB and they work fully, only this one doesn't.what should I look at?

I�m using Outlook to automatically send an email to my mobile phone. To bypass the stupid "security" bug in outlook I use redemption.safemailitem.Now, this has worked for years, but for some reason I can�t change the adress to which outlook sends the mail. Instead of sending to the adress in the code, it sends to an old adress that�s not anywhere in the code (but it was, ages ago)

I have a problem with strange character.
In mysql this character 💀 cause error Incorrect string value: 'xF0x9Fx92x80'
Samples of these characters are from [URL]
Say I want to analyze data from the web and found some strange character
how to remove this character 💀 ??
The occurance is rare.
In fact, how to know all characters that may be problematic for mysql and remove that? I am not saying escapeable characers. I am saying characters that are neither numeric, alphabeth, or chinese scripts, or punctuation. Characters that's totally bizarre.
How do I get rid of that from a string?
