Any way to change the case of a string using the String.Format command. For example, you can do this:
String.Format("{0,50}","My Info")
And it gives it a fixed width string output, I need to allow the user to change the case. All they can pass in is the format "{0,50}" so NO .net functionality, we wrap it up for them. In VB6 you could use a ">" "<" to change the case, surely M$ must have added a way to do this?
string function(s) to change only first letter of string to Upper Case?
View 7 RepliesI have all-one-case strings representing postal addresses stored in a database, but I want to capitalize US state abbreviations (e.g. " ca " to " CA ") when the abbreviation is separated from the rest of the string by a space on either side.The lousy way I could do it would be to have 50 statements like
If addressString.Contains(" al ") Then addressString.Replace(" al ", " AL ")
If addressString.Contains(" ak ") Then addressString.Replace(" ak ", " AK ")
...
Edit: That is a really lousy way! Here's what I did instead:
addressString = StrConv(addressString, VbStrConv.ProperCase)
'This needed to be done anyway, but it turns " ak " into " Ak ".
Static stateAbbrevs As New List(Of String)(New String() {" Ak ", " Al ", " Ar "...})
For Each a In stateAbbrevs
If addressString.Contains(a) Then

View 6 RepliesI am using the code from the following link. Basically I am using the built in functions in visual basic for encryption (Cryptography). Seeing as there is a lot of code for it, I posted a link to the code I am using.

I get what this is doing and how it is doing it...for the most part. My question is how do you let the user set the key to be used instead of it randomly generating one? One of the reasons I want this over the random key is that the user will be able to remember it easier and the key generated sometimes has weird characters in it that not everyone will no how to use. I have tried everything I can think of.
The encryption works good, all I am using it for is to encrypt/decrypt a text document. If this is not too good of an encryption, that does not matter as I am not using it to encrypt any highly sensitive information. All I need is a way to be able to allow the user to set the key, but every time I try to pass a string through the encryption() method instead of a generated key (in the generateKey() method) it will give me an error.

View 4 RepliesI am making a program that calculates various results with variables entered by the user. What I am trying to do is incorporate a function that will allow the user to switch from metric to imperial easily but only when the ok button is pressed. Now I got all the coding done for the metric and everything is working fine. My problem is when I use the radiobuttons to switch the entered variable in the text box to the desired unit it gives me a 0 or a random number in the textbox...
I also have labels indicating each variables unit which I easily managed to change with the text box using this code. :
'Change Labels to Metric
lblMDegreeC.Text = "Degree C"
lblMDegreeC2.Text = "Degree C"
lblMmm.Text = "mm"
lblMmm1.Text = "mm"
lblMmm2.Text = "mm"
lblMm.Text = "m"
lblMm2.Text = "m"
lblMm3.Text = "m"
lblMDegreeC3.Text = "Degree C"
I created all the coding to convert the metric variables to imperial. My problem is changing the textbox text when the user switches the units during run time. The labels change without a problem but the textbox never works. I have attached the coding for the file.
I am writting software for a touch screen (windows CE) as well as a desktop pc (windows XP)I have the software working for both, but the problem I am having is the Calendar.I need a Calendar for the current month, as well as allowing the user to go back to other months.I was going to use the control in vb.net called 'MonthCalendar' but when I add it to the form and make the control bigger (as in font) it adds to months when viewed on XP but when I copy the exe to the touch screen it only shows the 1 month like its ment to.Is there a better Calendar control I can use or does anyone know how to make it so that it only shows 1 month in the 'MonthCalendar' control?I am using VB.net 2008

I have a function that is getting passed a String and a DataRow.The String is a custom formatter. The idea is to do this
String.Format(passed_in_String, DataRow("ColumnINeed"))
The reason this is being done is at this point we have no idea what the column contains.However, if the formatter is "{0:MM/dd/yyyy}" and the DataRow("ColumnINeed") is an integer containing 42, String.Format is returning: MM/dd/yyyy In this situation I need it to throw an exception instead of returning nonsense.Is there anyway to make String.Format throw an exception if the object does not match what the format string is expecting?
I'm writing an Excel file recovery program with VB.Net that tries to be a convenient place to gather and access Microsoft's recommended methods. If your interested in my probably kludgy, error filled, and lacking enough cleanup code it's here: http:[url]..... The basic functionality seems to work although I haven't tested graph macro table recovery yet.
It occurred to me that Vista and Windows 7 users could benefit from being offered a list of previous versions of the file within my application if the Shadow Copy Service is on and there are previous copies. How do I do this?I looked at a lot of web pages but found no easy to crib code. One possibility I guess would be to use vssadmin via the shell but that is pretty cumbersome. I just want to display a dialogue box like the Previous Versions property sheet and allow users to pick one of the previous versions. I guess I could just display the previous version property sheet via the shell by programmatically invoking the context menu and the "Restore previous versions choice", however I also want to be able to offer the list for Vista Home Basic and Premium Users who don't have access to that tab even though apparently the previous versions still exist. Additionally if it possible I would like to offer XP users the same functionality although I'm pretty sure with XP only the System files are in the shadow copies.
I looked at MSDN on the Shadow Copy Service and went through all the pages, I also looked at AlphaVSS and AlphaFS and all the comments. I'm kind of guessing that I need to use AlphaVss and AlphFS and do the following?Find out the list of snapshots/restore points that exist on the computer.Mount those snapshots.Navigate in the mounted volumes to the Excel file the user wants to recover and make a list of those paths.With the list of paths handy, compare with some kind of diff program, the shadow copies of the files with the original.Pull out the youngest or oldest version (I don't think it matters) of those shadow copies that differ from the recovery target.List those versions of the files that are found to be different.This seems cumbersome and slow, but maybe is the fastest way to do things. I just need some confirmation that is the way to go now.
So I need a format string to pass to String.Format that would "move" the decimal point.I can't perform any math operations before doing the String.Format, so it has to work right off the bat.Basically I'm emulating a formatting string from a proprietary server. In it if I say:
"MR2"
for the value:
12345
The result is:
123.45
I'm close with this, but it's not spot on:
String.Format("{0:#0.##}", 12345)
an extra, but not necessary... there is also MR2Z, which moves the decimal 2 left, but if the value is 0 "" is returned.
