I need to find out if the user's screen is set to normal 96 dpi (small size), large 120 dpi fonts, or something else. How do I do that in VB.NET (preferred) or C#?
View 2 RepliesWhen I try and run the program I get an error stating
"Value was either too large or too small for a Decimal."
On the line that says
principal = payment - InterestPaid
I've included the rest of the code as well. Perhaps this is a downside of staring at the screen for so long.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim payment As Double
Dim result As String

I have writen a program in Visual Studio 2005 professional. Part of the program functions is to store customers details. Part of this details include a phone number. I can add a customer and include his/her telephone no. which is 12 digits long. But when retreiving this customer I get the following error.Value was either too large or too small for an Int32. Couldn't store <+23320805060> in Phone Column.Expected type is Int32.The program runs fine If the phone numer is less than or = 9 digits. The datatype i am using is for the phone column is varchar(50). I have tried to change the data type to bigint, int and nvarchar(50) but the problem seems to persist. I am using the SQL database but i seem to be hitting a brick wall on this matter.
View 10 RepliesI am working on fixing a bug in VB that is giving this error. I am new to VB, so there is some syntax that I am not fully understanding. The code that is throwing the error says:
.Row(itemIndex).Item("parentIndex") = CLng(oID) + 1000000
I understand that adding 1000000 is too much for an int16. I can't change that value (not right now anyway). What I don't understand, and can't seem to find, is what .Row is referring too.
I have a large wikipedia dump that I want to cut into different files (1 file for each article). I wrote a VB App to do it for me, but it was quite slow and crapped out after a few hours of cutting. Im currently splitting the file into smaller 50mb chunks using another app but thats taking a long time (20-30 minutes for each chunk). I should be able to cut each of these up individually if I do this.
Does anyone have any suggestions of a way to cut this file up quicker?
I have my software installed on numerous machines and on all but one it is fine, however on this final computer the font comes up very small. It is only in my software, nothing else on the computer. I'm using Arial size 10 and bold, nothing fancy and as i say it works on all the others.
View 2 RepliesSo, I have a little issue.. I can't currently explain it using the software I'm developing because it's "internal"... So I'm going to describe it as an email serverAnd the email server has a fair number of email accounts, and I want to save the accounts emailFor development, I've been saving it all in a list of a structure (this sounds worse than it is, the data actually is no more than 120 bytes per "email")

View 6 RepliesWithin our application, some of the object's text are effected by users with "Large font" turned on under Control Panel>>Graphic Properties. I can't determine what is the trigger to this behavior. I have many forms including TableLayoutPanels, ComponentOne Sizers, some objects with DOCK=Fill, and AUTOSIZE=TRUE. I wrote a simple Hello World form, and it is not impacted by the "large font" setting.

View 1 RepliesI am using VB .Net 2.0. I know I can detect the OS using
System.Environment.OSVersion
Can anyone tell me if there's a list somewhere where I can find what that generates for different OS versions.
Specifically I am trying to detect if a user is running Windows 7 64-bit.
How do I detect if an arbitrary user is an administrator on a machine? I have the user's domain and username but not password. The user is NOT the currently logged in user,so I can't just use WindowsIdentity.GetCurrent.
View 3 RepliesI have an application that when it starts, it checks the internet to see if a new version is available. My problem is this: If there is no net connection, the program 'pauses' as it tries to check for the new version.
Is there a function that I can use to detect if the user is currently online, with a working connection?
I'm trying to work out how to detect if the user has pressed an f key I have this so far:
Private Sub Form1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles Me.KeyPress
Label1.Text = e.KeyChar
End Sub
This detects when the user presses a character key and outputs it via Label1.text, but it doesnt work on all keys?
Dim hostname As IPHostEntry = Dns.GetHostEntry(TextBoxIP.Text)

I have a windows form with the code above to get the ip address of the user. what would be the easiest way to get the country location of the user? based on the IP in the textbox. The solution doesnt need to be 100% accurate but good enough to work most of the time. the simpler the better.is there are any work arounds or built in fuctions for pulling a users country or language, this would be better than creating or managing a giant database.
i have wrote a chat app and have it so it sends text to a rich text box my question is
how would i set it so a user can set there font color and when they talk it shows in that color to all other users but the nick name is in a diffrent color from the text
what I'm trying to do in the title. I've got a rich text box and two combo boxes. I used a code snippet to show all the installed fonts in the first one and I implemented the use of an integer for the text size. I think that what I've done is correct but the application throws an Inner Exception whenever I try to change the font or the text size.
