I have a rich text box which I use in order the user is able to add pictures, coloured writing, different font etc... however I need to load specific text in the rich text box when the user load the Form.how I can add (I guess) the HTML to load this every time the user load the form.
P.S the text will change depending on who loads the form so I can not do a simple
RichTextBox1.LoadFile("C:Documents and SettingsDesktopSigniture.rtf")
I am unable to load rich text files into my rich text box. It worked fine yesterday, would there have been anything I could have changed by accident?
With OpenFileDialog
.Filter = "Text format (*.txt)|*.txt|Rich Text Format (*.rtf)|*.rtf|All files (*.*)|*.*"
[Code]...
but I am getting the error File format is not valid when i attempt to open any Rich Text file
Currently, there are 2 forms and on form1.vb, it has rich text box which i've successfully load the .rtf file and I would like to link it to form2.vb whenever I click on a button that link to form2.vb. how can i do that as i tried to use {RichTextBox1.LoadFile("filename.rtf")} and it doesnt work when i click on button that link to form2.vb.

View 1 RepliesAfter the client finishes testing, they go to the results page and then my program returns them back to the secondary page.If they re-enter the testing page again, for a second go-around, with out completely leaving the program as I have been doing since I was tweaking the code after each run, the repetition counter is not resting back to Zero. It�s still retains the information from the previous testing phase.
Example:The client chooses how many testing cycles they want to go through, from 1 to the total amount available to them to test. Right now its only 5.When they first start testing, it starts at �1 of 5�, then progresses at one increment for each drug they test on. Once they reach 5 and answer their final question, the program then goes to the results page and then to back the secondary page. If they choose to re-enter the testing page without totally leaving the program, the testing page counter sits at �5 of 5�. Shouldn�t the page be resetting the variables each time it loads?
I'm trying to execute different code depending on the button clicked (button 4 or 5) on Form1, but when I click on button5 to activitae the code on the Form2's Load event everything is Ok, but when I click the back button to return to Form 1 and click on the Button4 to activate the code on the Form2's Load event again, it doesn't active the Form's Load event, is there a way to form the form load event every time I access it from Form1?

View 7 RepliesI have an MVC application which sets some session variables based on internal static IP addresses.I have built an ApplicationController to override the OnActionExecuted sub in MVC for data that I need to use throughout my application.However, the code below, which is just a snippet of my code but is edited for my post, only partially works. On initial page load, the session variables aren't saved, but after a page refresh they are. The issue I have is that these need to be saved on the initial page load.
If Session("Item1") = Nothing Then
If IpAddressShort <> "" Then
Dim locInfo = cmsRepository.GetInfoBasedOnLocation(IpAddressShort).SingleOrDefault()
If locInfo IsNot Nothing Then
[code]....
Theoretically, if I'm correct, if there is no Session("Item1") set/if Session("Item1") is empty, then the rest of the snippet should run and set those variables.How come this isn't setting those variables on the first time the page load?
I'm looking for some advice on a very simple application which should consist of 2 parts:The application should display a splash screen for 5 seconds Before the splash screen displays, the program should execute code which sets some Environment Variables and then starts another EXE after which this application should terminate. As a complete novice to VB.Net I've been reading countless articles & examples on splash screens but they all seem geared towards a solution which will load a further form after the splash screen or contain snippets of code that I have no idea how or where to use. On my app however, I don't want any further form to be visible so can someone please advise the steps to follow that will achieve what I am looking for.
The following code Forum Account kindly converted that sets the environment variables and starts another EXE

I have a few combo boxes that need to be loaded up once and displayed multiple times (whenever the main form is opened) The reason for this is because it's taking about 10 seconds for the form to load each time it's opened due to unnecessary re-querying.
Here is an example of what I have as a combo box source and what I've done.
I've put the query, connection, etc... in a module and call it on the login form - i don't get any errors but the data does not load into the combos.
'In Module

View 7 RepliesIs there a way to load the data for my form during the splash screen and simply show the form when the user clicks on the button? I'm using a thread which fills my DataAdapter using Form.DataAdapter.Fill(Form.Dataset.Table), but when I open the form the data isn't shown (I removed the line from my form_load event to prevent a double load). Is there anyway to tell the form that the DataAdapter has been filled already and to look at the information there instead of loading the data everytime the form loads?
My problem is that the form takes a while to load due to the amount of data it is looking for. If I could already have the data ready and then display the form when the user clicks a button it'd be perfect. I apologize if I'm missing something, this is my first time diving into VB.Net with VS2010 after using Access VBA for awhile.
I'm trying to figure out how to resize a form on load to fit to the user's screen. Many of my users are on laptops, or split screens between laptop and monitor..I remember in VB6, it was something like form.height = screen.height (or something of the sort)... but I can't find this functionality in VB.NET 2008. I'm also trying to wrap everything (multiple screens/forms) into one app, so I wanted to know if anyone was aware of any tutorials on form parent/child relationships... I don't want to keep opening and hiding forms individually without having them packaged in one work area....
View 9 RepliesI would like to display my splash screen for a set amount of time (5 seconds). While the splash screen is displayed, I added code to the load function to determine which form to load next. I have the splash screen selected in the Application Properties settings. I also have to select a "Startup form:" in the Application Properties settings.
I'm having a couple of problems. First, the form selected in the "Startup form:" is loaded and displayed along with the splash screen.Next, the form I select in the splash screen load is not started. Only the "Startup form:" is loaded.
Let's say I want to put a 10 second delay on my splash screen before loading the next form or app.I use a timer, but would it be a simple integer value or several different lines of code?
