I am working on a a program that uses a textbox to display data from a telescope. Normally the data is standard ASCII characters, but there is one time when the data is displayed as blocks to indicate the number of degrees to go. The textbox font is set to Sans Serif in the property box. When I show the blocks, I want to switch to Wingdings. I have searched how to change the textbox font and tried several ways found, but none of them work. I know that the textbox will handle Wingdings - I can set the font property and it displays correctly.
The most common method I have seen is: txtDisplay1.Font = New Font("Wingdings",26.0, FontStyle.Regular) ,but like all the other methods tried, the font never changes.
Is it possable to create a save document and control its font type?
im trying to create a .txt file, but when i/someone else opens it comes up in another font type like Arial.
So my textbox is in say Arial font but when i save and recall it, it comes up as say webdings.

View 8 RepliesIm writing a app using vb.net, which has multiple front ends e.g a windows service and a windows forms app. Ive got all my business logic and database stuff compiled into 1 project (producing a dll) then the different front ends as different projects calling the dll.
In the backend / dll project Im connecting to 2 databases using app.config to store the connection strings and DataSets / TableAdapters. This all works fine .... Until
When I deploy the windows app, it deploys the exe and the dll produced by the backend project. when its installed on a client PC, Im need to point the app at a different db server and therefore need to change the connectionstring, but its packaged up in the dll.
is there any way I can use a settings file within my windows app (therefore deployed with my windows app) where I can define the connectionstring, which onload gets passsed through into my dll, so the backend connects the correct database. I know how to pass standard settings through (strings etc) but the my.settings.connectionstrings seem to be readonly.
i have a program i've made a while, and one of the users wants to be able to load his own images to the background instead of the plain grey that is there now. i've searched and searched, and basically can get this working
BackgroundImage = Image.FromFile("C:UsersMeFileName.png")
i just slapped that onto a button just to get it to work as i was experimenting. but that only works for a file of that name, on my computer, in that folder. what i'm looking to do is get it so a user can browse his own directories for images and upload them as the background on the form. and be able to save the settings as well. but so far i have only seen different ways to load preset images that you can load. if it's even possible? i'd assume that you'd use the openfiledialog command, but i'm not that well versed in vb as of yet.

I have a forms application and I have multiple localizations for it. I've figured out how to add a button to a form, to change the localization and then read all the labels/etc and change them to the other language.What I would want to do instead now is click a button and it changes to the other language the current form but also the entire application so that any other windows opened while the application is open open in that other language.[code]This is the code I use when a button is clicked on a form to change it to Hindi the current form. However I want to when the button is clicked, change application to continue to run on that localization instead for the remainder of the time it is open.[code]

How do we overwrite config file at runtime. I have four config files for DEV, TEST, UAT, PROD. Based on user selection I need to overwrite the default config file completely with one of the selection specific config files. These config files not only have appsettings section, but also has complex cutom sections and subelements with lot of attributes. I need to overwrite and refreshsections dynamically at runtime. I know there are so many articles on editing appsettings sections. But I want to completely overwrite the entire file.
View 1 RepliesI am working on a contract to repair problems in a application that interfaces with a custom built digitizer tablet.The application recognizes the tablet at startup, initiates calibration to locate the pad limits and then saves those limits to file.During the run of the application the user has a cursor that is changed to a line with a X on the left hand side of it. The user then uses this custom cursor to click in a PDF document where they would like the contents of the Digitizer pad to be placed. When they click a box signifying the size of the digitizer pad along with the same blank and X appears. What I have been having issue with is that the box and the line with the X appear most of the time but on occasion the line and X appears at either the top or bottom of the box and the click is no longer at the line with the X but somewhere in the middle of the box. This really screws up things and often the user has to uninstall and re-install the application to get it righted.
The values that save the calibration points are bound to variables during the build process, there is a separate routine to calibrate the digitizer pad if the user desires to do it again.

In my app (written in VS 2003) I use OleDbDataAdapter's to load data. I have some functions that enable be to change the OleDbDataAdapter.SelectCommand.CommandText at run time, by adding a "WHERE" or "HAVING" section to the SQL command, or updating the "WHERE " or "HAVING" section. This way I have have generic load data functions. (load all invoices for Customer 123, load all invoices for the year 2009, or load all invoices for Customer 123 for the year 2009).

I am developing an windows application in VB 2008, My requirment is such that I have to change the applications Splash and Startup object on the basis of "Custom Constants" (Compilation Constants).As far as I have .Net idea it should be done in Application.Startup Event (guide me if i am wrong)Now, in Application.Startup_Event when I write the code
Private Sub MyApplication_Startup(ByVal sender As Object, ByVal e As Microsoft.VisualBasic.ApplicationServices.StartupEventArgs) Handles Me.Startup
My.Application.SplashScreen = SplashScreen2

The application dont work as desired, instead it starts with Form2 (which is OK), while in case of Splash it doesnt changes the splash form.
I am trying to convert a value from a radio list box that is populated by an access database. The database loads fine, I have no trouble with that. My issue is that I am trying to take the value of the radio button chosen and turn it into a font color. Therein lies my problem. I see that it cannot be a string, but when I turn it into an object, I get an error.

View 2 RepliesI have made updates to my programs, including a large update with the fonts on my forms. The only problem is this font is not found on vista or Windows XP and must be downloaded. The program is completely ruined with its looks without it. Is their a way so that both Windows XP and Vista could download these fonts, On startup of the first form, Form Load maybe? Even if the user says that he or she would like to see the program with the fonts? I just don't want to take the many hours i wasted resizing with the new fonts, ect. If it would be easier I could ask the user if they are using Windows XP, Or Vista?
