Event handler on an external form/module

Hello

I have a simple, but important question: How can I raise events of my form1 on another module/form?

My form tempalte is crowded with events (50 of them contextmenustrip events)

How can I place those events on another form/module to clean it up a little?

Try using #region instead... organize the code, put things into regions, then collapse the regions. If you move the event handlers to another location, you're going to just complicate things.

You could also use a partial class to hold blocks of code.

You would need to refactor your code. Not only are so many events unrealistic but also hard to debug and maintain.

I assume most of those event handlers are repetitive and can be consolidated into fewer methods. Also you can group the event handlers that have same body by just appending the appropriate Handles clause to it, and using the sender parameter of event handler which is seldom used.

Well, I am making a code editor program.
All those 50 events cause one sub to add a particular type of code to the tweaker field.

Here is an example of those code:

Code:

---

    Private Sub ToolStripMenuItem10_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ToolStripMenuItem10.Click
        'Ability
        Dim value As String = "rem ---BeginComp:Ability ---"
        value &= vbCrLf & "ObjectTemplate.createComponent Ability"
        value &= vbCrLf & "ObjectTemplate.Ability.hasHealingAbility 1"
        value &= vbCrLf & "ObjectTemplate.Ability.hasRepairingAbility 1"
        value &= vbCrLf & "ObjectTemplate.Ability.hasAmmoAbility 1"
        value &= vbCrLf & "ObjectTemplate.Ability.radarRadius 10"
        value &= vbCrLf & "rem ---EndComp ---"
        AddCodeToTextboxNoReplace(value)
    End Sub

---

And I have 50 of them, and sometimes all those (minimized) comps open and then it takes minutes to minimize them all again.

Anyone has an example/tutorial/checklist to place these events somewhere else?

I assume that you are just changing only one line in that procedure (i.e. radarRadius value) for each menu item. If this is the case then you can handle all of them in same event procedure like this:

vb.net Code:

Private Sub ToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) _
                Handles ToolStripMenuItem10.Click, ToolStripMenuItem11.Click, ToolStripMenuItem12.Click   '<-- all all of them here
 
        Dim radarRadius As String = CType(sender, ToolStripMenuItem).Name.Substring(17) ' remove the word 'ToolStripMenuItem' from it
                                                                                        ' so that we are left with only the number.
        'Ability
        Dim value As String = "rem ---BeginComp:Ability ---"
        value &= vbCrLf & "ObjectTemplate.createComponent Ability"
        value &= vbCrLf & "ObjectTemplate.Ability.hasHealingAbility 1"
        value &= vbCrLf & "ObjectTemplate.Ability.hasRepairingAbility 1"
        value &= vbCrLf & "ObjectTemplate.Ability.hasAmmoAbility 1"
        value &= vbCrLf & "ObjectTemplate.Ability.radarRadius " & radarRadius
        value &= vbCrLf & "rem ---EndComp ---"
        AddCodeToTextboxNoReplace(value)
    End Sub

Ah wait, well not that I want to change the radius, lol, but this does give me an idea how to get the clicked toolstrip. Thanks, I'll try some testing, then I can change 50 subs to 1 =D

Ok works, very, very much thanks you's for the "CType(sender, ToolStripMenuItem).Name" code, it was exactly what I needed =D

At this point it looks like this:

Code:

---

  Private Sub CompMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles _
        ToolStripMenuItem3.Click, ToolStripMenuItem4.Click, ToolStripMenuItem5.Click, ToolStripMenuItem6.Click, _
        ToolStripMenuItem7.Click, ToolStripMenuItem8.Click, ToolStripMenuItem10.Click, ToolStripMenuItem11.Click, _
        ToolStripMenuItem12.Click, ToolStripMenuItem13.Click, ToolStripMenuItem14.Click, ToolStripMenuItem15.Click, _
        ToolStripMenuItem16.Click, ToolStripMenuItem18.Click, ToolStripMenuItem19.Click, ToolStripMenuItem20.Click, _
        ToolStripMenuItem21.Click, ToolStripMenuItem23.Click, ToolStripMenuItem24.Click, ToolStripMenuItem26.Click, _
        ToolStripMenuItem27.Click, ToolStripMenuItem28.Click, ToolStripMenuItem29.Click, ToolStripMenuItem30.Click, _
        ToolStripMenuItem31.Click, ToolStripMenuItem33.Click, ToolStripMenuItem34.Click, ToolStripMenuItem36.Click, _
        ToolStripMenuItem37.Click, ToolStripMenuItem38.Click, ToolStripMenuItem40.Click, ToolStripMenuItem41.Click, _
        ToolStripMenuItem43.Click, ToolStripMenuItem44.Click, ToolStripMenuItem46.Click, ToolStripMenuItem47.Click, _
        ToolStripMenuItem48.Click, ToolStripMenuItem49.Click, ToolStripMenuItem50.Click, ToolStripMenuItem52.Click, _
        ToolStripMenuItem53.Click, ToolStripMenuItem55.Click, ToolStripMenuItem56.Click, ToolStripMenuItem57.Click, _
        ToolStripMenuItem58.Click, ToolStripMenuItem59.Click
        Dim type As Integer = CType(sender, ToolStripMenuItem).Name.Substring(17)
        Dim value As String = ""
        If type = 3 Then
            value = "rem ---BeginComp:DefaultPenetrateComp ---"
            value &= vbCrLf & "ObjectTemplate.createComponent DefaultPenetrateComp"
            value &= vbCrLf & "ObjectTemplate.penetrate.neverPenetrate 0"
            value &= vbCrLf & "ObjectTemplate.penetrate.allowSolidPenetration 1"
            value &= vbCrLf & "ObjectTemplate.penetrate.allowLiquidPenetration 1"
            value &= vbCrLf & "rem ---EndComp ---"
        End If
        If type = 4 Then
            value = "rem ---BeginComp:DefaultProjSoundComp ---"
            value &= vbCrLf & "ObjectTemplate.createComponent DefaultProjSoundComp"
            value &= vbCrLf & "rem ---EndComp ---"
        End If
        If type = 5 Then
            value = "rem ---BeginComp:DefaultRicochetComp ---"
            value &= vbCrLf & "ObjectTemplate.createComponent DefaultRicochetComp"
            value &= vbCrLf & "rem ---EndComp ---"
        End If
        If type = 6 Then
            value = "rem ---BeginComp:DefaultSoundComp ---"
            value &= vbCrLf & "ObjectTemplate.createComponent DefaultSoundComp"
            value &= vbCrLf & "ObjectTemplate.sound.maxSoundsPerBurst 1"
            value &= vbCrLf & "ObjectTemplate.sound.noisy 0"
            value &= vbCrLf & "rem ---EndComp ---"
        End If

Thanks :thumb:

By the way, you can close all open subs and regions in one shot with Ctrl+M+O.

I would organize the whole thing with regions.
