Is there any specific way of calling the form of another application.My main project is a WPF application.From that it is calling another application is Vb.NET.. This is done by creating a process and then calling the exe.
Dim fp1 As New Process()
fp1.StartInfo = New ProcessStartInfo("Location of the exe")
fp1.Start()
Now the problem which I am facing is that from that exe I need to call a specific form in the WPF application.

View 5 RepliesFor reasons that are beyond my control, I have three Projects. Projects A and B reference project C. Project A references project B so that it can open a large form in project B. I now need to open that large form from project C, but VB won't allow me to add a reference from C to B because that would create a circular dependency. I found a way around it, though. I created a Timer in A, and when I opened C from A, I passed in that timer. When the user performs a certain action, I enable the Timer from A, and this causes C to open B for me.

Are there any functions that can be called across the project.I mean we cn use Private Sub ABC() function in the document where it has been declared but is there any way that this could be called from any other form?

View 7 RepliesI have a vb6 project in which I use a dll library to do some tasks. For that, I add a module which declares all functions of that library such as:Declare Function myFunction Lib "abcdapi.dll" (ByVal hVar1 As Long, ByVal hVar2 As Long) As Long When I call this function (and many other similar) I'm able to do the work and correct Long pointer is returned. But when I try to do the same thing by VB.net (by importing the same library using dllimport and calling the same function), I get no result. although it does return some pointer but that doesn't produce correct result.

As per [URL] How can I achieve this? 'processPacketVB' is a 'variable' but is used like a 'method' is the error I'm getting with these references to the project and class and function.
using VBProcessPacket;
namespace UIST {
public partial class FormActionMenu : Form {
private void timerDelay_Tick(object sender, EventArgs e) {
VBProcessPacket.ProcessRX processPacketVB = new VBProcessPacket.ProcessRX();
//read the receive buffer as a string
RXpacket = processPacketVB("test"); // processPacketVB throws the error 'processPacketVB' is a 'variable' but is used like a 'method'
I have a question regarding VB.Net and Object-oriented programming.
I have a solution consisting of two projects.
One project is dedicated to the logic of the application, and one is only to show the Winforms form, and to reflect changes made in the logics project. In other words, when an array filled with various attributes residing in the logics project gets changed, then these changes should be reflected on the form (not that strange in theory).
Here comes the - for me - really tricky part:
I have created user controls, and these are residing in the forms project and placed on the aplication's form. When I click on any one of them, their respective onclick sub gets called okey, but how can I send a message to the logics project from their onclick subs? Basically, I'm not sure on what should be private or not, or possibly how to call the other project correctly. In any case, I can't get it to work.
To sum up: What I need is a line of code calling a class in another project, and someone telling me what should be private, static etc.
I'm having an interesting issue that I can't reproduce on a different project, but can consistently on this one. I have no clue what might be causing it, but am hoping that someone may have seen it before.
I have a main form, from which I run a series of checks. On this form, I have a listview control. Because of some issues with the refreshing of this listview control, I had to create my own messagebox. It's just a form that displays some text ( it also happens to look nicer than MsgBox; in my opinion, anyways ). It's been working great for months, until recently.
My problem is that on my main form's load event, I run this check, which returns an error within a try/catch block. I then call my custom messagebox with a message. It in turns calls it's ShowDialog() function.
In any other situation ( after the main form has been loaded ), I have no problems. The messagebox goes on the screen and behaves appropriately ( ie: waits for my input and acts as a modal dialog ( stops execution of my main form's thread ) ). However, on this onload event, my messagebox comes up and goes away almost immediately afterwards.
I've traced it all the way to the showdialog() call. For no explicable reason, it appears to skip right over this call, without me doing anything on the form.
Here's what the inner trace looks like ( when I put a breakpoint on the onclosing event for this messagebox form ):
CODE:
Requested were made by Businese Analyst to set the few Main FORMs VISIBLE PROPERTY TO FALSE when the POPUP FORM is loaded.
[Code].....
When the MAIN FORM loads the POPUP FORM, on the FRMPOPUPCUSTOMER-FORMLOAD even, it has to set the MAIN FORM Visible to False.
When FRMPOPUPCUSTOMER FORM IS UNLOAD it has to set the MAIN FORM Visible = TRUE.
How to the coding is to ensure that different MAIN FORM when loaded FRMPOPUPCUSTOMER it will turn the MAIN FORM Visible to FALSE.
how to call a function from a different form. Like the button click event. i have this scenario. I have a main form and a child form in the main form there is a navigation panel on the left side controlling the child form. What i want is if clicking the add record in my navigation panel will call a function in the child form to execute.
View 1 RepliesI have two forms and one needs to call a method from another form. I am from a java background so i do not understand why the object instaniated (if that is a correct assessment) on one form cannot Call a sub from the second form.

MsgBox("found form")

but thing is when i find the form i want to call a sub in that form's code called action if i use frm.actions() it says that actions() is not a member of [URL]so how do i do this?
I am just wondering the difference between using "As New" and not using it. It looks like the outcome is same to me. Is there any difference between #1 and #2 when I call "frmCR" from other winform?
A form "frmCR" is alreadu created thru design mode.
#1
Dim frmCR As New frmCR
frmCR.Show()
#2

I have a solution with several projects most of which are code or control libraries. I have a main windows forms application that references and uses these libraries. What i am trying to do is create a 2nd windows application that extends the main one, but i would like to be able to deploy them as separate exe's.
When i try to add a reference to the new app referencing the main app; all seems fine until i try to run the new app i get several error msgs similar to below:
Error 1 Could not find file 'ADODB.dll' referenced by assembly 'D:Visual Studio 2005ProjectsXXXinDebugXXX.exe.manifest'. <newAppName>
i have tried adding references to all the dll's in the error messages and they are still listed when i try to run the new app. I thought of a few work arounds but they require user changes to maintain separate exe's at deployment. I would like to avoid this if possible.
I have login form as start up form and i call Form1 after successful validation and in Form1, i have close button on click of Close i would like to reset username and password fields on loginform to null. If i add code in form1 below i get exception Dim fmLogin As New LogInForm

Is it advisable to call a function from another form?Does it have any side effects on the system while running, like more process will consume?I have a function that will set the background in a form, it will make the image stretch, backcolor transparent and will set the picture. If I will use that function in other 15 FORMS I can minimize my code.

Problem:
Form 1 contains a SWF object, which is called FlashGame (it has a movie set, which is a game)
Form 2 contains a button to set a variable on the FLashGame.
Example
Call FlashGame.SetVariable("variable will be here", 1)
That simple coding works when the button to call that SetVariable command is on the same form as the FlashGame, but I need them to be on different forms.
The code below is what I have in one form. Login_prompt is the name of the other form.In this code snippet I am displaying another form that prompts the user for a username and password.I then want to open the website and auto populate the fields. The populating is not the problem.I cannot seem to call on the other form's sub procedure correctly.
View 3 Repliesi am currently trying to re-write an old VB6 program into .net basically the program contains 100's of forms for different jobs each with a Public Sub runjob(). the form names are then stored on a database. the user then selects the job from the listbox and it calls the correct job.the code i use to use in vb6 was
sValue = database.rsselectjobrun.Fields("callname")
Set frmName = Forms.Add(sValue)
frmName.runjob
Set frmName = Nothing i have looked into it and found this code which calls the form in .net
Dim objForm As Form
Dim sValue As String
Dim FullTypeName As String

but i cannot get this to run anything other then the formload code. i know i can put all of this into a select case module but id rather not with the amount of forms i would have.
There are 2 forms open for the user in a school attendance program. The 1st. form is called FormBrowseClasses and the other form is called FormBrowseGrades. On the 2nd form is a procedure called PopulateTheDataGridWithData. That procedure loads data into a DataGrid.We would like to call PopulateTheDataGridWithData from within FormBrowseGrades so the data in the DataGrid will be refreshed.
We already tried:
' Refresh DataGrid data on FormBrowseClasses
'-------------------------------------------
objFormBrowseClasses.PopulateTheDataGridWithData()
but this only runs on a new instance of the form, not the currently open form. how to set this up correctly?
What is the difference between these?

They are all showing the form and I know it has difference but I don't know what. Can somebody explain this?
Is there anyway I could set an image on a "NEW" child form when calling the following
(MainFrm) = Form1
(ConfigFrm) = form2
Code:
Dim Frm as New ConfigFrm()
ConfigFrm.Img_Artwork.image = Image.fromfile(Img_Location)
Frm.MdiParent = MainFrm
Frm.show
When I call the following, and the "New" child form gets called, The picturebox is left blank. I know it's because I'm calling "NEW" but is there anyway to still add the image to the picturebox even though i call "NEW"
I am using VS 2008 and I have a solution with multiple projects. I would like to know how to open a form in project B from a Form in project A. The solution starts with the form in project A.I have tried the following and it does not produce the expected behaviour:In Form A I have added a reference to the Project B. The following code is in a form in project A. appraisal is a form in project B.
Dim appraisalForm As New appraisalApp.appraisal
appraisalForm.Show()
The above solution works to a degree. As the form is instantiated in Project A, I cannot reference any of the items in the form in Project B as I could if the Form in project B was instatiated through startup.
I have an MDI form with 3 nested children with in it. As of right now all it can do is display a new form.For example: each time I press the menu button, the new child form(Form1) is created. Now, if I press that same menu button a second or subsequent time a new Form1 is created and it appears over the previous one.
What I would like is that each time the event handler is triggered (a menu item_click on the parent form) that instead of a completely "new" child form being produced(a new window popping up) it would instead pull up the appropriate child form that is attached to the trigger.
