Has any one come across any software suitable for this task (i.e. can be built into vb.net). I have tried using MS MapPoint, which according to the write up says it will do the job, but I cannot get it to work (posting on here didn't get any response) so I wondered if there was a more popular mapping utlity out there?

how do you show information from a datagrid cell to show up in a text box in another form, this is for a college project.
View 1 RepliesI'm new in .Net and I have an application with windows form "LOGIN" When users enter the user and password and click "ok", then if user passes validation then I have the code Show(MDIMainMenu) (I'm trying to open an mdi form), but I receive the following error: "Form that is already visible cannot be displayed as a modal dialog box. Set the form's visible property to false before calling Show. Error Number 5"

I have a program that uses two forms. The program opens to the Main form, and the user can navigate to the other form from the Main form through use of a button. Here's the way I've currently written it: When the Main form loads, it declares and instantiates the other form during the load procedure. When the user presses a button, the second form is displayed by means of the ShowDialog method. On the second form, there is a Return to Main Screen button which closes the second form, bringing the user back to the Main form.
So, here's the structure of the code:
Code:
Public Class frmMainForm
Dim frmSecondForm As New SecondForm
Private Sub btnSecondForm_Click(blah, blah, blah) Handles blah, blah, blah
[CODE]...
Here's my reasoning: Originally, I wrote the code so that a new instance of the second form was created every time the button was pressed. The problem was that whatever data was displayed on the second form, previously, was lost when the user returned to it a second time. Since the user would be switching back and forth between these forms, frequently, I needed that data to persist.
What is the best practice for accomplishing this:
1) Declare and instantiate the second form on program start, as I have done, and use the button simply to show the form?
2) Declare and instantiate the second form each time the button is pressed but maintain the variables on the Main form and pass them ByRef to a custom constructor for the second form? Is this even possible?
3) Something else?
Im trying to create a stopwatch in one form and another form show my progress bar using a combo box for mins and seconds to show the progress bar on form1 1
[Code]...
I am trying to use a progressbar to show on main form and then finish when next form is loaded, I have got this code.
1. When I click on button, it must open next form, but the next form must only open when the data in my list box has been loaded from Access Databse. When I run my program, it only shows the progressbar and don't open the next form.
Main form code:
Public Class Main
Dim PB As ProgressBar
Private Sub main_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
End Sub
[CODE]............................
Using the code below:

This was a guess, after looking at the Form.ShowDialog method in reflector.My question is, is there a managed call I can make to acheive the same result, and what does a button click do that other clicks don't?
ETA: The problem does not occur if I open the form using a key.
This is a database app where I am trying to check for possible duplicates and give the user the option to keep the new record or assign to an existing record.In form1 the user will enter data into a textbox. I use this information to build a bindingsource.filter. Then I call another form (form2.show()) to display results to user and get user response. This part all works correctly.
The problem is that as soon as form2.show() executes, I loose the contents of the textbox - and it appears that I am no longer in the bindingsource.addnew() method.

View 2 RepliesI have a series of methods being called for my networking code. An event gets fired from the networking thread. Inside this event, which I've hooked into from a singleton class, I route messages to form level methods which they register on form load to handle certain messages they care about. Inside of these form message hooks I need to close the current form (which I was able to do) but also show a different one (which is giving me the trouble).

I have a dual monitor setup on my computer. My program has multiple forms. I've designed the program to check which monitor the main form is currently on and to open the secondary forms on the current monitor. When the main form is on the primary monitor the secondary forms open as FormWindowState.Normal which is the design-time setting for the secondary forms. If the main form is on the secondary monitor and I click to open a secondary form then the secondary form is to be displayed as FormWindowState.Maximised.
[Code]...
So I moved the Form.Show line to after the Form.WindowState line. This works fine when the Form.Show process is very quick. The problem is that one of the secondary forms downloads some information from the internet so it takes about a second to finish the Form_Load process. When I had Form.Show first the form would not appear on screen until the Form_Load process is complete, so the delay was in the form appearing at all which is how I prefer it. With Form.Show last the form appears on screen immediately but appears mostly blank and unresponsive until the Form_Load process completes.
I would prefer that the form not appear at all until the Form_Load process is complete but I would like it to appear in an already Maximised state. Is this achieveable? It doesn't seem that complicated but I just can't figure it out.
I've come across a situation where I try to run a simple line of code in a method Dim res As DialogResult = frmOptions.ShowDialog()but nothing happens. The dialog box will not appear. If I run this method from another location in the code it executes fine (i.e. displays the form in dialog mode and code executes fine thereafter). Hence, it may be the way in which I arrive at this code that is causing my problem, but I cannot see to find what is wrong.
When I pause the debugger the line of code is highlighted in green but I can't see to step over it or into it what may cause this to happen, or what I should be looking for that might be causing the problem??

View 2 RepliesI have a main form that i show at run-time (Form 1). While Form 1 is showing, I show another small (Form 2) form to provide the user with some additional options to chose from. You can see how I show this second form below in EXAMPLE 1. When the user is done with the second Form, I want to Hide it and return to the first form Form 1. However when the second form is hidden, it does not return me to the first form when I use the Show method for Form 1.
Note I am in development mode as I test this. When the second form hides, the first form stays collapsed at the bottom of my desktop. I can click on it and it will pop up and everything is fine. However, I cannot seem to get pleasing transition from Form 2 to Form 1 using the code in EXAMPLE 2. Note that I do not Hide Form 1 to begin with. I am assuming that this is why the Show method does not work. However I cannot figure out why it collapses in the first place. Is there a Focus property that I need to set for Form 1?

I having trouble with the WindowsState Maximized Property. I have a MDI WinForm application with a number of Child forms. I setup up each Child form with the WindowsState Maximized Property in the Property screen of the VS 2008. The MDI Container form is also Maximized.When I run the application, the MDI Container opens Maximized as it should. When I try to open a Child form it opens partaly Maximized. The MenuStrip and ToolStrip are Maximized including the MenuStrip having the Close, Maximized, and Minimize controls in it. On the form, the BindingNavigator and the Form itself is the size they would be if the WindowState was Normal.If I Minimize the MDI Container form and bring it back the Child form will be fully Maximized as it should be.

View 2 RepliesI have a problem I am trying to solve in an elegant manner. I have a .net application that I have created. I am trying to get one of the forms to be shown from a webpage. This sounds strange I'll admit, so here is the backstory
We have some large monitors at work, that show information on them. I have no control over how the information is displayed. Currently they are just using a browser and tabbing in the browser to show each different piece of information on the screen. Most of the info they show is just standard html stuff, text and images.
Now along comes my winforms application. The part of the application I need to show is a graphical display. Everything on this display is drawn using GDI+, if that matters. I need to get this form into a format that I can show. Below is my own solution, but I am pretty sure this is not the best method, but it may be the only method I can use[code]...
I though about doing something with the clients, however the clients are not always up, so I could have periods where the image wouldnt be updated.
I also was thinking about an ASP.net solution, but that would require me to learn ASP.net, and I am not quite ready to take that challenge
