If we format a value for percent "{0:#%}" then it will become 400%, and this also applies to all the 3rd party controls I've tried. I've used custom format as a workaround for this but perhaps you guys could enlighten me on this one. If a user inputted 4 for example then did the user intended 4% or 400%? If it were me that I would expect the 4 to be 4% rather than 400%.
View 11 RepliesHow do you enter in a code for an overall letter grade from a percentage given? I have a seperate box for the letter grade and a seperate one for a the percentage grade . I have it setup when an overall grade and possible grade is entered into boxes it will give me a grade percent but not a letter grade. How is that added? I am doing this for my course project but dont undersatnd the coding very well. I am just trying to pass the class.
View 1 RepliesIf I type this code (VB.net 2003):
Dim myDialog As frmTestDialog
myDialog = New frmTestDialog
myDialog.Show()
you'd expect some dialog window to appear in a non-modal state. For some reason, this isn't the case with a program I am working on. Most of the dialogs use ShowDialog() to open them, and one uses Show(). The second I try to show another non-modal dialog, the dialog appears in a modal state. Another strange thing is, before I show the dialog, there is code to shift the dialog location to centre it on the main form - this isn't executed either: the dialog appears at 0,0.
My usual trend is to blame myself for errors (usually the case), then I blame the software; I have checked every single line of code (including the generated code), and it all checks out - the dialog should be non-modal. But ... it's not. I've come across other errors in VB.net 2003; is this another instance?
I'll try creating a new dialog and displaying this non-modal, and see what happens. If it works, I can just transplant the code but this shouldn't be happening, just like if I go to a shop, ask for a cola, I expect a cola not a Chinese panda; more annoying, I return the panda, ask for a cola, and they give me the panda back do loop until I give up The system does using threading, but none of that code connects to the display dialog routines all dialogs are opened with more-or-less the above code (a few have simple validation routines).
Take the below example. I would expect the IsInterned method to return null, because this string can't possibly be in the intern pool having started up the test app for the first time? I would also expect, that if I did something like string.intern("this112233StringCan'tPossiblyBeInTheInternPool!£$%") first, then this would legitimately be returned by IsInterned from the pool. I've also done the same in c# and the behaviour is the same.
Whenever I use strings in code, I tend to do something like textbox.text = string.intern("someValue") etc or if (textbox.text = "someValue") etc. Infact, whever strings are being used, I've gotten in to the habbit of using string.intern. Is this a bad habbit rather than using constants or the resources file?

After right clicking on the form Context Menu give option to see 'View Code Window' which opens the the view code window and shows from the first line of code in the file, where actually it should show Event handlers related to the control on which Mouse was right clicked. right now we have to go through the line of codes to locate the event related to particular control.Also after double clicking on the control, VB inserts a default event handler to Code file which should happen only when there is no Event Handlers added for that control previously & if a previously added Event Handler present, double clicking controls should locate that procedure.[code]after dragging dataset table to the form vb assigns 'field name' concatinated with 'TextBox' to TextBox Control likewise 'field name' concatinated with 'ComboBox' for ComboBox Control where it is difficult to locate them in Controls Member list into code..Instead why don't you prefix them with 'txt' for TextBox, 'cbo' for ComboBox etc. It is then easy to find one in code. Or make the original Optional.

I need to write a program allowing the user to enter up to five passwords at one time. I have the textboxes set the way I need. When the user presses the button, the code should check every password they ve entered, and flag any passwords that are invalid. A valid password includes the following:
At least 6 and not more than 15 characters
At least one uppercase alpha character
At least one lowercase alpha character
At least one numeric character
I'm a little confused about how to check each character of the entered passwords for these conditions.Because it must include alpha characters, I believe I have to do something with ASC and CHAR variables. This is my first post and I need to have this done within a few hours, haha. Help would be awesome.

The situation: I have a datagridview with one column (col1). In the datagrid definition (design view), i have created this row, and set the formatting to C2 (or C0, or C - I tried them all). then, I load my datagrid view pro programmatically :
dbl_myValue as double
dbl_myValue = 6.99
datagridview1.item(0,0) =
dbl_myValue
The datagridView shows the data correctly : 6.99$. When I "spy" on the datagridview.item(0,0), the "Value" property is a Double.
the problem: It don't work if the user manually enter a value : click in the cell, enter a numeric value (let's say 100, without decimal to avoid complexity) and then LEAVE the cell (so no more in EDIT mode). The formating just don't applies. When I "spy" on the datagridview.item(0,0), the "value" property is a STRING. So I guess this is the problem, but how can i do?
I want to limit and verify the textboxes data which enter by the user i want to make a class in which i pass the textfield and the methods in that class return boolean value . First method check only numbers with decimal point. second method check only A to Z or a to z with some specify charecters. In java it is very easy by the parse INt methods or use class.
