I've created an Excel COM add-in that has several forms. The application has the following forms:
FormA (Modeless): Excel.Application is parent
FormB (Modal): FormA is parent
FormC (Modal): FormB is parent
[code].....
sometimes (not everytimes), when I call the Me.Hide() in a form, which I called with .ShowDialog(), the main form, which called this dialog minimized.
View 2 RepliesI'm trying to hide 5 to 12 buttons on a form until a screenshot is saved to the clipboard. I have it set right now so the user clicks a button(btnSavePDF) and then whichever buttons are visible are made not visible. But I haven't a clue how to restore just those buttons. I'm trying to avoid restoring them all unless they were all originally visible.

I have a main form that has a button with which a smaller form is shown. Think of the smaller form as the Find/Replace dialog in many applications, such as Notepad. It's important that the form is (what I believe is called) modal. What I mean is that it always stays on top of the main form. I ensure that by calling the Show method with "Me" as the owner argument. Whenever the small form loses focus it will not disappear into the background but stay visible (albeit out of focus). If you don't understand open up Notepad and have a look at the behavior of the Find/Replace dialog.
Here's my problem: instead of actually closing the form when the X is pressed, I want it to simply Hide itself, so its position and the state of any controls (checkboxes etc) is preserved automatically.To achieve this I simply cancel the FormClosing event and Hide it:
vb.net
Private Sub Form2_FormClosing(ByVal sender As System.Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles MyBase.FormClosing
[code]....
To show the form, I use the following (note the (Me) to make the main form the owner of the form; this ensures that it remains visible even when it is out of focus):
vb.net
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Form2.Show(Me)
End Sub
Now. When I run my project, and open the Form2 (small form), then hide it again (by 'closing' it), I can no longer close the main form (Form1)! It seems the main form cannot close when the small form still exists (albeit invisible)...?? When I don't use the Me argument in the Show method, I don't get the behavior I want. I know I can set the TopMost property to True but that will also cause it to become visible on top of all the other forms, even windows not part of my application.
I have a parent form (form1), which is calling a second form (form2) as modal.[code]...
No form2 is modal. Closing this form2 from the form itself is clear.But how can I close the form via myform2.close from form1 via an event handler?

How can I disable temporarily a module ? If it cant then how can I disable the sounds of my form? I have a mouseover, hover and click event sound in my form and I want it to be disabled in my options. I make a module thinking that if I can disable my module but the use of a checkbox then it might work but if it will not the how can I do that? im thinking also of a simple if statement but I prefer simplier ones like disabling my module.

I'd like to prevent users form clicking on a form when i'm doing some background processing. To me it sounds simple in theory but apparently its not.

I'm curious if it is possible to hide a group of text boxes from view in a form until a particular condition is met, and to have a custom set of text boxes for that condition. To give an example; I want radio buttons offering choices for a manner of searching records, the user selects one and then a specific set of text boxes are displayed for the user to utilize, if a different option is chosen a different set of text boxes will be shown. Is this something that can be done?
View 7 RepliesI have a VB. Net App where I want the user to open a modeless form which contains reference information about items in a select box. If the user double clicks the item selected in the list box a modal form is opened to edit the item.I want the previously opened reference form to remain active/enabled, that is, I want the user to be able to click on it, move it, etc.I was able to get the form to at least show up on the task bar by setting it's "ShowInTaskBar" property to true, however, when it comes to the front the user can still not move it to the side to view all of the Edit Forms information.
View 7 RepliesI'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:
I want to be able to check if there is currently a dialog or modal form shown for my form so that I can close it.
Is there a way to do this?
I have a form in a vb.net windows form application called PolicyRefreshStatus.vb that has a ProgressBar control on it. From the main form called EditPolicy.vb I need to show PolicyRefreshStatus.vb over top of EditPolicy.vb - but the way things are wired I'm controlling the the ProgressBar and it's steps from logic inside EditPolicy.vbIf I display the PolicyRefreshStatus.vb bar using the .show() method things work fine.The problem is if the user clicks back on the main form then PolicyRefreshStatus.vb losses focus. If I show PolicyRefreshStatus.vb as a modal form using .ShowDialog() then execution halts in EditPolicy.vb after the .ShowDialog() statement.
so for example in the code:
mPolicyRefreshStatus = New PolicyRefreshStatus
mPolicyRefreshStatus.pbMax = mPolicy.ClaimsUpdateMax

I am trying to pass information to parent form from modal form in vb.net winforms application.
1.) I created a copy of a form and displayed it using following code.
dim f=new frmParent()
f.show()
2.) Depending on conditions a button on frmParent opens a modal child form and asks for some informations. I used following code for that:
dim f = new ChildForm()
f.showDialog()
Both code works fine. When user press saves in child form i need to close childForm and use the user types values in parent form. I know how to close the childform but not sure how to pass info from childform to parent form.

I have designed my app for multiple gridviews. When a user double clicks a row it opens up the data in a modal form and when they commit changes the row gets updated.While they have that modal window open they can not go back to the grid.But I have a alerts/messages window always running (like outlook tasks). As soon as I open the modal window I can not access that tasks window. (Default behaviour)How can I open the modal form and still let the user access/view the tasks window while they work on the modal window.(I tried creating it in a differant thread, but got a lot of cross thread errors so decided to abandon that approach.I thought that 2 modal form can run at the same time as long as they have differant parents. But aparently the main GUI thread pauses as soon as you open a modal window on it.

View 4 RepliesI have a situation where I need to display a Modal Window from a vb.net module and feed the contents to that modal form from the module.I am showing the form , feeding data to it from a class module and trapping the events in it using a timer control from the module.It works fine with Show() method but it doesn't with ShowDialog().If I used ShowDialog() then I was not able to continue with the code followed by it and not able to update any contents in the modal form.

I want to open a form as modal without using showdialog()Problem with showdialog() is we can not open the form as mdi child with it. i want to open few forms as modal but as mdi child forms. but i want to make sure user cannot go anywhere else without closing thst form.if we set parent form enabled = false then i can not set it as mdi child otherwise that form also becomes enabled=false.
if we write showdialog() then so many form icons will appear on taskbar. it we open as mdi child then only one icon appear i don't want to appear so many icons on taskbar so i want to open as mdi child but as modal
for eg. Mainform = mdi form
from mainform open formA = as mdi child of main form (but modal)
from formA open formB as child (modal)
from formB open formC as child (modal). if i use showdialog() then so many form icons on taskbar.

View 4 RepliesAs part of my design for a re-write of some vb6 code, i've got some business rules that check the data being entered. These rules run on the business layer, but if they find any data that is incorrect, they need to display a modal form showing the 'violation' (or could be a warning, a question or some information).
So what i'm after doing is to somehow display a modal form in my presentation layer triggered by my business layer.
The only solution i've come up with is to raise an event to get the modal form displayed, catch the event in the presentation layer and display the form (all items on the form would be bound and so would display the correct information). Problems with this is that i would then have to put the code to sleep in the business layer until i got a responce from the presentation layer.
All of my forms are MDI children. I have one form that is collecting input parameters for a report. One of the parameters needs to come from another form. For the life of me, I can't get it to work.

I have to message box code just to verify the selection. glbPart is just a hand off parameter to tell the frmVendorList code to come back to this form rather than where it was origianlly programmed to go.I tried a do until glbVendor <> "", but that put me into a death loop and I never got to select a vendor from the vendor list form. Obviously, the easiest would be if I could make frmVendorList Modal, but I can't see how to do that once it's been created modally.
