  • capture delete key in CListCtrl and do soem processing

    - by user333422
    Hi, I have a class which inherits from CListCtrl class, say class list. I have another class dlg, which inherits from CDialog. Class dlg contains an instance of class list. I have got a delete button in class dlg, on which I delete the selected item in listCtrl and do lots of other processing. I want the same functionality on delete key. I added OnKeyDown() fn is my class list, where I can capture VK_DELETE key. But my problem is that, how do I do otehr processing that I need to do in dialog class. All that processing is dlg class based not list class based. I have many such dlg classes with different data and in every dlg class processing is different. I tried capturing VK_DELETE in dialog class, but it doesn't capture it if focus is on list class. I am totally stuck and have no idea, how to do this. Please give me some idea how i can do this. Thanks, SG

  • Generating code for service proxies

    - by Hadi Eskandari
    I'm trying to generate some additional code base on the auto-generated webservice proxies in my VS2010 solution, I'm using a T4 template to do so. The problem is, automatically generated proxies are added in "Service Reference" folder but ProjectItems (files) are hidden by default and the following code does not find them in the project structure: var sr = GetProjectItem(project, "Service References"); if(sr != null) { foreach(ProjectItem item in sr.ProjectItems) { foreach(var file in item.ProjectItems) { //Services.Add(new ServiceInfo { Name = file.Name }); } } } The above code runs and although service reference is found, and there are ProjectItems under that node (named by the webservice reference name), under object under that node is of type System.__ComObject and I'm not sure how to progress. Any help is appreciated.

  • Tab Control Troubles

    - by VBeginner
    Best to explain with an example. TabControl has Tab1 and Tab2. I'm trying to make it so when Tab1 is selected, Button1 is visible and stays visible. When Tab2 is selected, Button1 is invisible and stays invisible. I need it to work when the Tab is clicked, not when the content area of the Tab is clicked. Thank you.

  • How to define an extern, C struct returning function in C++ using MSVC?

    - by DK
    The following source file will not compile with the MSVC compiler (v15.00.30729.01): /* stest.c */ #ifdef __cplusplus extern "C" { #endif struct Test; extern struct Test make_Test(int x); struct Test { int x; }; extern struct Test make_Test(int x) { struct Test r; r.x = x; return r; } #ifdef __cplusplus } #endif Compiling with cl /c /Tpstest.c produces the following error: stest.c(8) : error C2526: 'make_Test' : C linkage function cannot return C++ class 'Test' stest.c(6) : see declaration of 'Test' Compiling without /Tp (which tells cl to treat the file as C++) works fine. The file also compiles fine in DigitalMars C and GCC (from mingw) in both C and C++ modes. I also used -ansi -pedantic -Wall with GCC and it had no complaints. For reasons I will go into below, we need to compile this file as C++ for MSVC (not for the others), but with functions being compiled as C. In essence, we want a normal C compiler... except for about six lines. Is there a switch or attribute or something I can add that will allow this to work? The code in question (though not the above; that's just a reduced example) is being produced by a code generator. As part of this, we need to be able to generate floating point nans and infinities as constants (long story), meaning we have to compile with MSVC in C++ mode in order to actually do this. We only found one solution that works, and it only works in C++ mode. We're wrapping the code in extern "C" {...} because we want to control the mangling and calling convention so that we can interface with existing C code. ... also because I trust C++ compilers about as far as I could throw a smallish department store. I also tried wrapping just the reinterpret_cast line in extern "C++" {...}, but of course that doesn't work. Pity. There is a potential solution I found which requires reordering the declarations such that the full struct definition comes before the function foward decl., but this is very inconvenient due to the way the codegen is performed, so I'd really like to avoid having to go down that road if I can.

  • C#: proprietary DLLs requiring access to my assemblies

    - by Craig Johnston
    My solution uses a proprietary assembly, which when debugging the solution throws an Exception saying it can't find an assembly that is meant to be one of the projects in my solution. I cannot add a reference to the proprietary assembly because all I have is the DLL. When I compile everything into a single application directory and run the app it works fine, but I want to debug. Where should assemblies be placed if you want a proprietary assembly in the solution to see them? I assume the issue is that there is no path specified and it is just looking in a default directory of some kind.

  • jQuery "growl-like" effect in VB.net

    - by StealthRT
    Hey all, i have made a simple form that mimiks the jQuery "GROWL" effect seen here http://www.sandbox.timbenniks.com/projects/jquery-notice/ However, i have ran into a problem. If i have more than one call to the form to display a "Growl" then it just refreshes the same form with whatever call i send it. In other words, i can only display one form at a time instead of having one drop down and a new one appear above it. Here is my simple form code for the "GROWL" form: Public Class msgWindow Public howLong As Integer Public theType As String Private loading As Boolean Protected Overrides Sub OnPaint(ByVal pe As System.Windows.Forms.PaintEventArgs) Dim pn As New Pen(Color.DarkGreen) If theType = "OK" Then pn.Color = Color.DarkGreen ElseIf theType = "ERR" Then pn.Color = Color.DarkRed Else pn.Color = Color.DarkOrange End If pn.Width = 2 pe.Graphics.DrawRectangle(pn, 0, 0, Me.Width, Me.Height) pn = Nothing End Sub Public Sub showMessageBox(ByVal typeOfBox As String, ByVal theMessage As String) Me.Opacity = 0 Me.Show() Me.SetDesktopLocation(My.Computer.Screen.WorkingArea.Width - 350, 15) Me.loading = True theType = typeOfBox lblSaying.Text = theMessage If typeOfBox = "OK" Then Me.BackColor = Color.FromArgb(192, 255, 192) ElseIf typeOfBox = "ERR" Then Me.BackColor = Color.FromArgb(255, 192, 192) Else Me.BackColor = Color.FromArgb(255, 255, 192) End If If Len(theMessage) <= 30 Then howLong = 4000 ElseIf Len(theMessage) >= 31 And Len(theMessage) <= 80 Then howLong = 7000 ElseIf Len(theMessage) >= 81 And Len(theMessage) <= 100 Then howLong = 12000 Else howLong = 17000 End If Me.opacityTimer.Start() End Sub Private Sub opacityTimer_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles opacityTimer.Tick If Me.loading Then Me.Opacity += 0.07 If Me.Opacity >= 0.8 Then Me.opacityTimer.Stop() Me.opacityTimer.Dispose() Pause(howLong) Me.loading = False Me.opacityTimer.Start() End If Else Me.Opacity -= 0.08 If Me.Opacity <= 0 Then Me.opacityTimer.Stop() Me.Close() End If End If End Sub Public Sub Pause(ByVal Milliseconds As Integer) Dim dTimer As Date dTimer = Now.AddMilliseconds(Milliseconds) Do While dTimer > Now Application.DoEvents() Loop End Sub End Class I call the form by this simple call: Call msgWindow.showMessageBox("OK", "Finished searching images.") Does anyone know a way where i can have the same setup but would allow me to add any number of forms without refreshing the same form over and over again? Like always, any help would be great! :) David

  • Unable to add Solution to TFS 2010 due to existing (invisible)binding

    - by Refracted Paladin
    I have a smallish utility library I made that I had created in TFS Beta 2 to test out TFS. I now have TFS rc1 installed(and Beta 2 uninstalled) and am trying to add my Solution to TFS. I get an error saying that it is already bound to my old TFS, which was on a different system then this one. Strangely, when I go into Source Control and look at the bindings it says there aren't any. Also, I manually deleted the .vss and .vsc files and it still does it. Ideas? I looked through the numerous other SO topics related to this but unless I missed one none of them are dealing with my issue. Ideas?

    - by qulzam
    I found the code from the net in which i cant understand this line:- byte* p = (byte*)(void*)Scan0; There Scan0 is System.IntPtr. It is code of C#.Net. Plz Explain the above line.

  • Entity Framework Duplicate type name within an assembly (6.1.0)

    - by CodeMilian
    I am not sure what is going on but I keep getting the following exception when doing a query. "Duplicate type name within an assembly." I have not been able to find a solution on the web. I had resolved the issue by removing entity framework from all the projects in the solutions and re-installing using nugget. Then all of the sudden the exception is back. I have verified my table schema over and over and find nothing wrong with. This is the query causing the exception. var BaseQuery = from Users in db.Users join UserInstalls in db.UserTenantInstalls on Users.ID equals UserInstalls.UserID join Installs in db.TenantInstalls on UserInstalls.TenantInstallID equals Installs.ID where Users.Username == Username && Users.Password == Password && Installs.Name == Install select Users; var Query = BaseQuery.Include("UserTenantInstalls.TenantInstall"); return Query.FirstOrDefault(); As I mentioned previously the same query was working before. The data has not changed and the code has not changed.

  • How can I process a form's events in another class / module automatically in VB.NET

    - by CowKingDeluxe
    Here's my code: Public Class Form1 End Class Public Class Form1Handler Inherits Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click MsgBox("I") End Sub End Class I'm trying to get Form1Handler to process Form1's events automatically. How can I do this? Should I use a module instead? I'm doing this in VB 2010. I don't want to have to make an event handler in Form1 and then pipe it to the other class / module, is there some way to automatically "pipe" the events from form1 to form1handler?

    I use a form with border NONE. I need to override WndProc for resize and move form.

  • I have VS2010 Ultimate. Shouldn't TFS Server be included?

    - by George
    Dumb question I'm sure, but when I log onto my MSDN subscription account, I don't see Team Foundation Server in the list of available for download software application. I thought it was supposed to come with VS2010 Ultimate, which I could download. Is it a separate download? Could it be that my MSDN account level gives me access to VS2010 but that I am still not entitled to TFS? I'd like to install it instead of using VSS.

  • ACCESS 2003 Excel 2003 : VBA for opening Excel file from Access and copying a pictre from excel the

    - by Justin
    So I have an excel workbook that has a nice global map of shaperange objects. With some very simple code I can change the colors, group and ungroup collections of countries into arrays, etc...and it works pretty well. However, I would like to bring this into Access. So I could copy and paste all the shapes into an access form manually, but then they become pictures and I cannot change the colors of the countries (shaperange objects) to have the map act interactively as I can in excel. So I am thinking that I know how to use excel functions from access, and how to open excel from access. Is there a way to copy an object from excel (I know the file name and the shape name that i mean to copy everytime), and bringing it back to access to paste on a form? Atypical, I know, all my Access questions are. Thanks!

  • TFS: Choose which Team Project to add a solution too.

    - by Patricker
    I have a solution which I developed in VS2008 and which I am trying to add to Source Control (TFS 2010, though the issue happened in TFS 2008 as well). I have several TFS workspaces on my computer and I have access to several Team Projects. When I right click the solution in my Solution Explorer and choose the "Add Solution to Source Control" option I am never given an option of choosing which Workspace or which Team Project to add the existing solution too. VS2008 then proceeds to add it to the same team project every time. I have tried selecting an alternate workspace/team project in every window where I can see an option for it but it always adds it back to the same one. I even tried changing the name of my new workspace so that alphabetically it was the first thinking that it might be somehow related to that... no luck. I then tried goign to the Change Source Control window where you can add/remove bindings on a solution/project but that window also defaults to the same Team Project as trying to add the solution directly does... Any help would be greatly appreciated with this, maybe I'm just missing something?

  • DebuggerDisplay attribute does not work as expected!

    - by mark
    Dear ladies and sirs. I know that this attribute should work in C# and yet, in my case it does not. I have a class with a lazy property Children. Accessing this property may have a side effect of roundtripping to the server. So, naturally, I do not want this to happen when I just watch it in the debugger watch window. Omitting all the irrelevant details the source looks pretty ordinary: [DebuggerDisplay("(Frozen) {m_children}")] public IList<IEntityBase> Children { get { if (m_children == null) { m_children = FetchChildrenFromDB(this); } return m_children; } } And yet, when I watch the object and expand this in the watch window I do not see (Frozen) in the display, meaning the debugger simply ignores the attribute. Provided the image link is still valid it should be visible below: http://i28.tinypic.com/2zxo9s5.jpg The attribute is really there, according to Reflector. I use VS2008. Any ideas?

  • how do I zoom to normal text size in vs2008?

    - by gerryLowry
    I can not find any help on this issue in vs2008 help, Google, or SO. Scenario: I'm looking at a source file in vs2008 SP1; Windows 2003 Server SP2 Standard Edition, 1280x1024. The irrelevant name of this file is index.aspx. What is relevant is that the file has only 65 lines of code. The print is unreadably small--less than 4 point. It uses less than a third of the vs2008 text window vertically and less that a quarter of the vs2008 text window horizontally. It's not just index.aspx; e.g. another file with 142 lines only fills about 3/4 of the vs2008 text window vertically and less that a quarter of the vs2008 text window horizontally. Possible cause: Probably, but not certainly, I found the equivalent of zoom in/zoom out such as one finds in products like Microsoft Word. However, I've explored many vs2008 toolbars and other customization options and unfortunately I can not find out how to get myself out of this mess. Window, Reset Window Layout has no effect on the text size; my tiny text size did not change. QUESTION: how do I zoom vs2008 text size in and out and back to normal size? Thank you. Regards ~~ Gerry (Lowry)
