NativeWindow Class Skip / Ignore Messages On Right Clicking
Jan 5, 2010
I am using a class derived from NativeWindow to get access to WndProc for various text boxes on my form. I am trapping the WM_CONTEXTMENU message. I assign the handle in the Enter event and release it in the Leave event. Everything is working as expected except for one situation. If the user right clicks to select a new textbox, the first WM_CONTEXTMENU message is either skipped or is fired before the handle is assigned in my code. If I set a break point in the Enter event, the issue described above does not occur.
In all other cases, tabbing into the textbox, setting the focus to the textbox in code or left clicking in the textbox to select it, everything works as expected. To test the above, I also trapped WM_RBUTTONUP and display a message box. In all of the cases noted above except for selecting the textbox by right clicking it, the message boxes are displayed and then the context menu is displayed. When selecting a textbox by right clicking it, the message boxes are not displayed and the context menu is. Could this possibly be a bug in the NativeWindow class?
here I am again I have written a small class called 'Messages' that holds the user messages.The case is that I am not being able to import it. Here it is:
I need to avoid serializing an Event class member because when the event is handled by an object that is not marked as Serializable the serialization will fail.
I tried using the NonSerialized attribute on the Event class member but it fails to compile. This line of code:<NonSerialized()> Public Event PropertyValueChanged()
produces the following error: Attribute 'NonSerializedAttribute' cannot be applied to 'PropertyValueChanged' because the attribute is not valid on this declaration type.
Public Event PropertyValueChanged() ' compiles but needs the extra handling described below
Is there another way to avoid serializing Event members? This is not a problem if the event is not handled and I can work around it by cloning the objects (and ignoring the event) before serializing them. Just wondering if there is a better way.
We use a 3rd party engineering application that does not expose an automation model. We can 'automate' it after a fashion by using low level Win32 API calls. I can get the Process by iterating the GetProcesses method. Is there a way to attach to the app by using the NativeWindow class?
I'm using .Net Framework 2.0 with VS2005. I want to create a form associated to an external program (Microsoft Word, for instance). I want it to stay in front of this external program, but I don't want it to be modal.
but none of them have worked... (I aso changed the form name to its correct name instead of 0, but still no luck). Here is the html button I'm trying to click.
<div class ="user" > <input class ="button " type ="image " src ="/images/userbutton.gif " />
I want to use spy++ or Winspector But from what i Read they Dont work on windows 7 64bit Correct ? Im trying to read WM_COMMAND Messages from a App.And whenever i Select 'Log Messages' And find the windows etc.Nothing show's up. Is there a alternative ?
When the user clicks the Exit button it closes the forms and if there was an open file it asks the user is they would like to save. But after the application closes there is still memory being held in Processes by the application. However, when pressing the [X] in the top of the form the application closes again but in this instance it is not held in Processes. How do I write the close for Exit to take into account how the [X] works and close the application cleanly?

Someone asked me to add a function when the notifyicon is doublcliked. I figured that'd be easy with the mousedoubleclick event being available. I find out that then both the single and double will then be called. Well that sucks, I want it to only do the one the user requests. So I tried to get it to work:
Private Sub DblClick_Tick(ByVal sender As Object, ByVal e As System.EventArgs) Handles DblClick.Tick
I have a 'For Each' loop that contains some items I don't want to analyse. Now I use a GoTo command to 'skip' an item. But this is not very elegant and (knowing .NET) there is probably a way to skip to the next item without using GoTo.
I'll show you a simplified version of my loop, designed to add all animals to a list, except the Leopard : (Indeed, simplified, because there's like two pages of code in the real loop. )[code]....
following is the code at button event which copy data from one DGV (dgvAccesList) to another DGV (dgvProbReport) and its working properly. Its paste data to 3rd and 4th column of destination DGV.But the problem is that, if at source DGV first column and second column have data..lets say up to 2 rows..then its copied data starting from 3rd row..for the 3rd and 4th column..which is incorrect..its should be always start with first row of third and fourth column.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click For Each dgvRow As DataGridViewRow In dgvAccesList.SelectedRows Dim dgvNewRow As New DataGridViewRow dgvNewRow.CreateCells(Inward.dgvProbReport)
I have a datagridview and I want to click on it BAD to jump to 4 cell, but to walkwith the arrows is normal, I did this because the KeyDown / UP does not work becausethe cells are in Edit Mode:
Private Sub DataGridView1_EditingControlShowing (ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewEditingControlShowingEventArgs) HandlesdgvContactos.EditingControlShowing Dim EditingTxtBox The TextBox = CType (e.Control, TextBox)
I have a csv file generated with headings on the first row and data on the rest. The file varies each time and I have to have all these values for further usage. I'm using File.ReadAllLines(path) but could ignore the header row.
I am looping through several hundred records from a XML file and inserting in SQL server 2008 using LinQ from my Web Service.My question is, for some reason if a record is not inserted it is coming out of the loop and going to the Catch block directly.
Am experiencing a confusing situation where the debugging seems to skip arbitrary sections of code (including breakpoints) and then breaks on non-breakpointed lines. The call stack reports [External Code] even though its not external code

I'm using DataSet ReadXML() method to load XML files of records different tables, and all are working fine. But, I would like to have the exceptional handling that in case there're records in XML files got problem, e.g. invalid data format or exceed column width and etc, it will skip those records and continue loading remaining XML records into DataSet.
I really need line with this I can't figure this out . I am looping through items in a list view box, I am then adding them to a string. I need each new line in the listview box to be a new line in the string. I will then add this string an access database.But I can't get it to skip a line in the string
This is the code For Each lvItem As ListViewItem In lstVParts.Items
I have a collection of locations for a sales person, allowing them to send an item to multiple locations. I want to start reading at index 1 since I am using a collection. I saw an example where you can say something like "+ 1" (e.g. myitem.SelectedIndex + 1) to skip the first record. How can I skip the first record for the following:
Public ReadOnly Property Customer() As ICustomer Get Return CType(Me.CustomerList.Item(Me.CustomerNumSelected), ICustomer) End Get End Property
I tried to say Return CType(Me.CustomerList.Item(Me.CustomerNumSelected + 1), ICustomer) but it returns an error saying "string cannot be converted to a double". without the + 1 in there, I get an error that says "collection index must be in range 1 to size of collection".
I am using MSHFLEXGRID control to display data from an access-database table. The grid contains entries some of which are to be selected by the user but I want some of the rows to be disabled/skipped(avoid selection of those rows). I have grayed out the unusable rows and dont want the gray rows to be selected.
Code: Private Sub MSHFlexGrid1_RowColChange(ByVal sender As Object, ByVal e As System.EventArgs) Handles MSHFlexGrid1.RowColChange
Public Shared Function GetDataTable(ByVal PageSize As Integer, ByVal CurrentPagea As Integer) As DataTable Dim dtData As New DataTable dtData = da_Book_Content.GetDataContent()[code].....
On a page, I have DataList to display the data. It works but I want to implement the paging feature. How do I do that with so I be able to use Linq lazy loading feature ?
