  • What is a .NET app domain?

    - by Luke
    In particular, what are the implications of running code in two different app domains? How is data normally passed across the app domain boundary? Is it the same as passing data across the process boundary? I'm curious to know more about this abstraction and what it is useful for. EDIT: Good existing coverage of AppDomains in general at http://stackoverflow.com/questions/622516/i-dont-understand-appdomains

  • How can I setup a .NET Custom Action within WiX 3.0?

    - by Luke
    I need to setup a custom action within WiX 3.0. I have the following setup in my Windows application exe. I have viewed the question at StackOverflow: Removing files when uninstalling Wix however I can't get this working with WiX 3.0. This seems to deal with InstallUtilLib.dll, however I can't work out how I call the custom action within my main Windows app executable. Also, is there some method that I can use to manually invoke and test the OnBeforeUninstall function is working as expected? Imports System.Configuration.Install.Installer Imports System.IO Public Class CustomInstaller Inherits Configuration.Install.Installer Protected Overrides Sub OnBeforeUninstall(ByVal savedState As System.Collections.IDictionary) MyBase.OnBeforeUninstall(savedState) Try End Sub End Class

  • for loop not suitable?

    - by Luke
    I have created a for loop. I am trying to loop through lots of members and create a row for each member in a table. It's looping through too many times. Is it the right type of loop to use? <?php for ($i = 1; $i = count($u); $i++) { ?> <tr> <?php echo "<td>$i</td>"; ?> <?php foreach ($u as $username) { echo "<td>$username</td>"; } ?> <?php foreach ($p as $points) { echo "<td>$points</td>"; } ?> </tr> <? } ?> $u and $p are arrays. Thanks

  • Is there any way to get MSVC to pass structs arguments in registers on x64?

    - by Luke
    For a function with signature: struct Pair { void *v1, *v2 }; void f(Pair p); compiled on x64, I would like Pair's fields to be passed via register, as if the function was: void f(void *v1, void *v2); Compiling a test with gcc 4.2.1 for x86_64 on OSX 10.6, I can see this is exactly what happens by examining the disassembly. However, compiling with MSVC 2008 for x64 on Windows, the disassembly shows that Pair is passed on the stack. I understand that platform ABIs can prevent this optimization; does anyone know any MSVC-specific annotations, calling conventions, flags, or other hacks that can get this to work? Thank you!

  • [C#] Onpaint events (invalidated) changing execution order after a period normal operation (runtime)

    - by Luke Mcneice
    Hi all, I have 3 data graphs that are painted via the their paint events. When I have data that I need to insert into the graph I call the controls invalidate() command. The first control's paint event actually creates a bitmap buffer for the other 2 graphs to avoid repeating a long loop. So the invalidate commands are in a specific order (1,2,3). This works well, however when the graphed data reaches the end of the graph window (PictureBox) where the data would normally start scrolling, the paint events begin firing in the wrong order (2,3,1). has anyone came across this before? why might this be happening?

  • What is the best way to determine the path to the ISV directory?

    - by Luke Baulch
    MSCRM 4.0 Problem: I'm currently storing xml files in the ISV directory along with my web applications. From a plugin (or potentially a seperate app), I need to find an easy way to navigate to the ISV directory to read these xml files. This routine will be called extremely often, so processing minimization should be a strong consideration. Potential solutions: Registry: There is a registry key called 'WebSitePath' with the data 'C:\Inetpub\wwwroot\CRM'. Could potentially use this to build the path. (Will this be the same on all systems/installations?) IIS directory data: Looping through the DirectoryEntries of path '"IIS://localhost/W3SVC"' I could obtain the the web application where description is equal to "Microsoft Dynamics CRM". (Will this be the same on all systems/installations?) Webservice: Create one to read and return the data contained in these xml files The webservice would have easy access to its executing directory. Database: Store the data of these files in the database. Help: Can anyone suggest a simpler solution to obtaining and reading a file from the ISV directory? If not, which of the above solutions would be the quickest to process? Thanks for any and all contributions.

  • Changing Graphic Instance using ActionScript

    - by Luke Duddridge
    Hi, I was wondering if it is at all possible to change the "Graphic" used in a frame dynamically using actionscript. I was hoping to either change the image the Graphic is an instance of or change the Graphic I am using in the current frame. Cheers Addition: Could I have a layer for each Graphic and then using action script choose which layer shows?

  • ESRI frameworks: java vs javascript

    - by Luke
    I'm about to develop a web mapping application with ESRI Products like ArcGIS Server and Image Server. I can't find a good comparison between the Java Web ADF and the Javascript Framework. They're of course different because one is a full environment and the other is only client side but it's much more concise and the step to start is minimal. Another problem is that the Java Web ADF is not compatible with our current application server (JBoss 4.2.2) and require an old 4.0.2 version. Someone out there has experience that can help me? Many thanks.

  • Delete section of streamreader

    - by Luke
    I am reading a file into my program using streamreader. private void loadFile() { lstDeliveryDetails.Items.Clear(); if (!File.Exists("../../MealDeliveries.txt")) { MessageBox.Show("File not found!"); return; } using (StreamReader sr = new StreamReader("../../MealDeliveries.txt")) { //first line is delivery name string strDeliveryName = sr.ReadLine(); while (strDeliveryName != null) { //other lines Delivery d = new Delivery(strDeliveryName, sr.ReadLine(), sr.ReadLine(), sr.ReadLine(), sr.ReadLine(), sr.ReadLine(), sr.ReadLine()); mainForm.myDeliveries.Add(d); //check for further values strDeliveryName = sr.ReadLine(); } } displayDeliveries(); } Eventually I end up with all the deliveries in the following array public static ArrayList myDeliveries = new ArrayList(); It is loaded into the listview. I select an item as follows: iDeliverySelected = lstDeliveryDetails.SelectedItems[0].Index; I am struggling to understand how I can select an item and use a delete button to remove it from the text file?

  • Neither IE or Firefox respects the control values that are output

    - by Luke Rohde
    I'm writing a survey designer asp.net mvc. It has buttons to move questions up and down. The buttons post the whole form back and the affected questions are swapped on the server. When the form returns the only thing that is changed are the values for each survey question. Both firefox and IE seem to ignore this change. Nothing is persisted to the database (until save) and url doesn't change so the post just returns the same view but I've stepped through my code to ensure the sequence of values being rendered in the view reflects the swap which is ok. However "view - source" doesn't show the change suggesting caching issue (maybe auto complete). I've tried autocomplete="off" in my form. Response.Cache.SetNoStore(); in my global.asax [System.Web.Mvc.OutputCache(NoStore = true, Duration = 0, VaryByParam = "*")] before my controller and the following in my page header NOTHING!!! This must be real common. Anyone got a clue?

  • Why doesn't this Perl array sort work?

  • Why is PackageInfo.requestedPermissions always null?

    - by Luke
    I'm trying to enumerate all the permissions used by all the installed packages, however when I check the requestedPermissions property for each of my installed packages it is always null. The following is the code that does this: private HashMap<String, List<String>> buildMasterList() { HashMap<String, List<String>> result = new HashMap<String, List<String>>(); List<PackageInfo> packages = getPackageManager().getInstalledPackages(PackageManager.GET_PERMISSIONS); for (int i = 0; i < packages.size(); i++) { String[] packagePermissions = packages.get(i).requestedPermissions; Log.d("AppList", packages.get(i).packageName); if (packagePermissions != null) { for (int j = 0; j < packagePermissions.length; j++) { if (!result.containsKey(packagePermissions[j])) { result.put(packagePermissions[j], new ArrayList<String>()); } result.get(packagePermissions[j]).add(packages.get(i).packageName); } } else { Log.d("AppList", packages.get(i).packageName + ": no permissions"); } } return result; } Edit: Oops! I just needed to pass the PackageManager.GET_PERMISSIONS flag to getInstalledPackages(). Updated the code snippet.

  • Why don't my scrollbars work properly when programmatically hiding rows in silverlight Datagrid?

    - by Luke Vilnis
    I have a Silverlight datagrid with custom code that allows for +/- buttons on the lefthand side and can display a table with a tree structure. The +/- buttons are bound to a IsExpanded property on my ViewModelRows, as I call them. The visibility of rows is bound to an IsVisible property on the ViewModelRows which is determined based on whether or not all of the parent rows are expanded. Straightforward enough. This code works fine in that if I scroll up and down the grid with PageUp/PageDown or the arrow keys, all the right rows are hidden and everything has the right structure and I can play with the +/- buttons to my hearts content. However, the vertical scroll bar on the right hand side, although it starts off the correct size and it scrolls through the rows smoothly, when I collapse rows and then re-expand them, doesn't go back to its correct size. The scrollbar can still usually be moved around to scroll through the whole collection, but because it is too big, once the bar moves to the bottom, there are still more rows to go through and it sort of jerkily shoots all the way down to the bottom or sometimes fails to scroll at all. This is pretty hard to describe so I included a screenshot with the black lines drawn on to show the difference in scrollbar length even though the two grids have the same number of rows expanded. I think this might be a bug related to the way the Datagrid does virtualization of rows. It seems to me like it isn't properly keeping track of how tall each row is supposed to be when expansion states change. Is there a way to programmatically "poke" (read hack) it to recalculate its scrollbar size on LoadingRow or something ugly like that? I'd include a code sample but there's 2 c# files and 1 xaml file so I wanted to see if anyone else has heard of this sort of issue before I try to make it reproducible in a self-contained way. Once again, scrolling with the arrow keys works fine so I'm pretty sure the underlying logic and binding is working, there's just some issue with the row height not being calculated properly. Since I'm a new user, it won't let me use image tags so here's the link to a picture of the problem: http://img210.imageshack.us/img210/8760/messedupscrollbars.png

  • Reading a text file

    - by Luke
    I am trying to achieve a situation where i load a file into the program. I can use streamreader for this. Each record will be 7 lines long. Therefore lines 1,8,15,22,etc will all hold the same value. As will 2,9,16,23, etc and so on. What is the best way to achieve this? So that when i load the records in the listview, it recognises what i just said. Thanks

  • Scalable Ticketing / Festival Website

    - by Luke Lowrey
    I've noticed major music festivals (at least in Australia) and other events that experience a peak in traffic when tickets go on sale have huge problems keeping their websites running well. I've seen a few different techniques used to try combat this such as short sessions and virtual queues but they dont seem to have much effect. If you were to design a website to sell a lot of tickets in a short amount of time how would you handle scalability? What technologies and programming techniques would you use?

  • Temporarily impersonate and enable privileges?

    - by Luke
    We maintain a DLL that does a lot of system-related things; traversing the file system, registry, etc. The callers of this DLL may or may not be using impersonation. In order to better support all possible scenarios I'm trying to modify it to be smarter. I'll use the example of deleting a file. Currently we just call DeleteFile(), and if that fails that's the end of that. I've come up with the following: BOOL TryReallyHardToDeleteFile(LPCTSTR lpFileName) { // 1. caller without privilege BOOL bSuccess = DeleteFile(lpFileName); DWORD dwError = GetLastError(); if(!bSuccess && dwError == ERROR_ACCESS_DENIED) { // failed with access denied; try with privilege DWORD dwOldRestorePrivilege = 0; BOOL bHasRestorePrivilege = SetPrivilege(SE_RESTORE_NAME, SE_PRIVILEGE_ENABLED, &dwOldRestorePrivilege); if(bHasRestorePrivilege) { // 2. caller with privilege bSuccess = DeleteFile(lpFileName); dwError = GetLastError(); SetPrivilege(SE_RESTORE_NAME, dwOldRestorePrivilege, NULL); } if(!bSuccess && dwError == ERROR_ACCESS_DENIED) { // failed with access denied; if caller is impersonating then try as process HANDLE hToken = NULL; if(OpenThreadToken(GetCurrentThread(), TOKEN_QUERY | TOKEN_IMPERSONATE, TRUE, &hToken)) { if(RevertToSelf()) { // 3. process without privilege bSuccess = DeleteFile(lpFileName); dwError = GetLastError(); if(!bSuccess && dwError == ERROR_ACCESS_DENIED) { // failed with access denied; try with privilege bHasRestorePrivilege = SetPrivilege(SE_RESTORE_NAME, SE_PRIVILEGE_ENABLED, &dwOldRestorePrivilege); if(bHasRestorePrivilege) { // 4. process with privilege bSuccess = DeleteFile(lpFileName); dwError = GetLastError(); SetPrivilege(SE_RESTORE_NAME, dwOldRestorePrivilege, NULL); } } SetThreadToken(NULL, hToken); } CloseHandle(hToken); hToken = NULL; } } } if(!bSuccess) { SetLastError(dwError); } return bSuccess; } So first it tries as the caller. If that fails with access denied, it temporarily enables privileges in the caller's token and tries again. If that fails with access denied and the caller is impersonating, it temporarily unimpersonates and tries again. If that fails with access denied, it temporarily enables privileges in the process token and tries again. I think this should handle pretty much any situation, but I was wondering if there was a better way to achieve this? There are a lot of operations that we would potentially want to use this method (i.e. pretty much any operation that accesses securable objects).

  • What is good server performance monitoring software for Windows?

    - by Luke
    I'm looking for some software to monitor a single server for performance alerts. Preferably free and with a reasonable default configuration. Edit: To clarify, I would like to run this software on a Windows machine and monitor a remote Windows server for CPU/memory/etc. usage alerts (not a single application). Edit: I suppose its not necessary that this software be run remotely, I would also settle for something that ran on the server and emailed me if there was an alert. It seems like Windows performance logs and alerts might be used for this purpose somehow but it was not immediately obvious to me. Edit: Found a neat tool on the coding horror blog, not as useful for remote monitoring but very useful for things you would worry about as a server admin: http://www.winsupersite.com/showcase/winvista_ff_rmon.asp

  • Android programmatically add buttons to layout from string array

    - by Luke Batley
    Does anyone know how to programatically add buttons to the layout from an array? I have an array of titles and icons that i have used for a list view and now i'm wanting to reuse the same arrays to create a layout as displayed here so the layout adds a button for each item in the array and arranges them in 3's according to device width. is this possible to do? I have tried using a custom Array Adapter to generate the Grid but getting a null pointer error at the point menuGrid = (GridView) findViewById(R.id.gridView1); MenuItemsSetup menuData[] = new MenuItemsSetup[] { new MenuItemsSetup(R.drawable.ic_menu_icon1, "menuItem1"), new MenuItemsSetup(R.drawable.ic_menu_icon2, "menuItem2"), new MenuItemsSetup(R.drawable.ic_menu_icon3, "menuItem3"), new MenuItemsSetup(R.drawable.ic_menu_icon4, "menuItem4"), new MenuItemsSetup(R.drawable.ic_menu_icon5, "menuItem5"), new MenuItemsSetup(R.drawable.ic_menu_icon6, "menuItem6"), new MenuItemsSetup(R.drawable.ic_menu_icon7, "menuItem7"), new MenuItemsSetup(R.drawable.ic_menu_icon8, "menuItem8") }; String[] menuBgColours = {"#FFFFFF","#FFFFFF", ,"#888888", "#FFFFBB", "#BBFFFF","#000000", "#666666"}; CustomArrayAdapter adapter = new CustomArrayAdapter(this, R.layout.drawer_list_item, menuData, menuBgColours); menuList.setAdapter(adapter); menuGrid.setAdapter(adapter);

  • form not showing

    Perhaps this has something to do with it being the mainForm, but I'll ask the question. I have my mainForm that is the first to load when the program is booted.

The code: private void addFrmBtn_Click(object sender, EventArgs e) { saveForm saveform = new saveForm(); saveform.Show(); this.Close(); }
