  • VB6 app not executing as scheduled task unless user is logged on

    - by Tedd Hansen
    Hi Would greatly apprechiate some help on this one! It may be a tricky one. :) Problem I have an VB6 application which is set up as scheduled task. It starts every time, but when executing CreateObject it fails if user is not logged on to computer. I am looking for information on what could cause this. Primary suspicion is that some Windows API fails. Key points Behaviour confirmed on Windows 2000, 2003, 2008 and Vista. The application executes as user X at scheduled time, executed by Windows Task Scheduler. It executes every time. Application does start! -- If user X is logged on via RDP it runs perfectly. (Note that user doesn't need to be connected, only logged on) -- If user X is not logged on to computer the application fails. Failure point Application fails when using CreateObject() to instansiate a DCOM object which is also part of the application. The DCOM objects declare .dll-references at startup (globally/on top of .bas-file) and run a small startup function. Failure must be during startup, possibly in one of the .dll-declarations. Thoughts After some Googling my initial suspicion was directed at MAPI. From what I could see MAPI required user to be logged on. The application has MAPI references. But even with all MAPI references removed it still does not work. What is the difference if an user is logged on? Registry mapping? Environment? explorer.exe is running. Isn't the user logged on when application executes as the user? What info would help? A definitive answer would be truly great. Any information regarding any VB6 feature/Windows API that could act differently depending on wether user is logged on or not would definitively help. Similar experiences may lead me in the right direction. Tips on debuggin this. Thanks! :)

  • Learning Treetop

    - by cmartin
    I'm trying to teach myself Ruby's Treetop grammar generator. I am finding that not only is the documentation woefully sparse for the "best" one out there, but that it doesn't seem to work as intuitively as I'd hoped. On a high level, I'd really love a better tutorial than the on-site docs or the video, if there is one. On a lower level, here's a grammar I cannot get to work at all: grammar SimpleTest rule num (float / integer) end rule float ( (( '+' / '-')? plain_digits '.' plain_digits) / (( '+' / '-')? plain_digits ('E' / 'e') plain_digits ) / (( '+' / '-')? plain_digits '.') / (( '+' / '-')? '.' plain_digits) ) { def eval text_value.to_f end } end rule integer (( '+' / '-' )? plain_digits) { def eval text_value.to_i end } end rule plain_digits [0-9] [0-9]* end end When I load it and run some assertions in a very simple test object, I find: assert_equal @parser.parse('3.14').eval,3.14 Works fine, while assert_equal @parser.parse('3').eval,3 raises the error: NoMethodError: private method `eval' called for # If I reverse integer and float on the description, both integers and floats give me this error. I think this may be related to limited lookahead, but I cannot find any information in any of the docs to even cover the idea of evaluating in the "or" context A bit more info that may help. Here's pp information for both those parse() blocks. The float: SyntaxNode+Float4+Float0 offset=0, "3.14" (eval,plain_digits): SyntaxNode offset=0, "" SyntaxNode+PlainDigits0 offset=0, "3": SyntaxNode offset=0, "3" SyntaxNode offset=1, "" SyntaxNode offset=1, "." SyntaxNode+PlainDigits0 offset=2, "14": SyntaxNode offset=2, "1" SyntaxNode offset=3, "4": SyntaxNode offset=3, "4" The Integer... note that it seems to have been defined to follow the integer rule, but not caught the eval() method: SyntaxNode+Integer0 offset=0, "3" (plain_digits): SyntaxNode offset=0, "" SyntaxNode+PlainDigits0 offset=0, "3": SyntaxNode offset=0, "3" SyntaxNode offset=1, "" Update: I got my particular problem working, but I have no clue why: rule integer ( '+' / '-' )? plain_digits { def eval text_value.to_i end } end This makes no sense with the docs that are present, but just removing the extra parentheses made the match include the Integer1 class as well as Integer0. Integer1 is apparently the class holding the eval() method. I have no idea why this is the case. I'm still looking for more info about treetop.

    I'd like to populate a google map with several markers. When the user clicks on a marker I would like it to send the user to a different webpage which is designated for that location. (for example: lets say the markers represent homes, when you click on a marker it takes you to a page with more information about the home) What is the simplest way to do this?

  • Accessing the project system from a Visual Studio MEF Editor extension

    - by Daniel Plaisted
    I'm writing a Visual Studio editor extension using the VS 2010 SDK RC. I'd like to be able to figure out what the references of the current project are. How do I get access to the project corresponding to the current editor? The documentation on editor extensions doesn't seem to include information on how to access non-editor parts of Visual Studio. I did some searching and it looks like in VS2008 you could write add-ins that would access the project system, but I'm trying to get at this functionality from a MEF editor extension.

  • Text to Speech in ASP.NET - Access is denied... what to do?

    - by Magnetic_dud
    On my personal website, i would like to make it "pronounce" something I solved the "concept" problem, as in here, and on my desktop it works smoothly when launched from visual web developer. Creates a file, and then an embedded player in the page will play it. Perfect. So, I uploaded it on the server... I get this error 500: Server Error in '/sapi' Application. Access is denied.

  • Use native HBitmap in C# while preserving alpha channel/transparency. Please check this code, it works on my computer...

    - by David
    Let's say I get a HBITMAP object/handle from a native Windows function. I can convert it to a managed bitmap using Bitmap.FromHbitmap(nativeHBitmap), but if the native image has transparency information (alpha channel), it is lost by this conversion. There are a few questions on Stack Overflow regarding this issue. Using information from the first answer of this question (How to draw ARGB bitmap using GDI+?), I wrote a piece of code that I've tried and it works. It basically gets the native HBitmap width, height and the pointer to the location of the pixel data using GetObject and the BITMAP structure, and then calls the managed Bitmap constructor: Bitmap managedBitmap = new Bitmap(bitmapStruct.bmWidth, bitmapStruct.bmHeight, bitmapStruct.bmWidth * 4, PixelFormat.Format32bppArgb, bitmapStruct.bmBits); As I understand (please correct me if I'm wrong), this does not copy the actual pixel data from the native HBitmap to the managed bitmap, it simply points the managed bitmap to the pixel data from the native HBitmap. And I don't draw the bitmap here on another Graphics (DC) or on another bitmap, to avoid unnecessary memory copying, especially for large bitmaps. I can simply assign this bitmap to a PictureBox control or the the Form BackgroundImage property. And it works, the bitmap is displayed correctly, using transparency. When I no longer use the bitmap, I make sure the BackgroundImage property is no longer pointing to the bitmap, and I dispose both the managed bitmap and the native HBitmap. The Question: Can you tell me if this reasoning and code seems correct. I hope I will not get some unexpected behaviors or errors. And I hope I'm freeing all the memory and objects correctly. private void Example() { IntPtr nativeHBitmap = IntPtr.Zero; /* Get the native HBitmap object from a Windows function here */ // Create the BITMAP structure and get info from our nativeHBitmap NativeMethods.BITMAP bitmapStruct = new NativeMethods.BITMAP(); NativeMethods.GetObjectBitmap(nativeHBitmap, Marshal.SizeOf(bitmapStruct), ref bitmapStruct); // Create the managed bitmap using the pointer to the pixel data of the native HBitmap Bitmap managedBitmap = new Bitmap( bitmapStruct.bmWidth, bitmapStruct.bmHeight, bitmapStruct.bmWidth * 4, PixelFormat.Format32bppArgb, bitmapStruct.bmBits); // Show the bitmap this.BackgroundImage = managedBitmap; /* Run the program, use the image */ MessageBox.Show("running..."); // When the image is no longer needed, dispose both the managed Bitmap object and the native HBitmap this.BackgroundImage = null; managedBitmap.Dispose(); NativeMethods.DeleteObject(nativeHBitmap); } internal static class NativeMethods { [StructLayout(LayoutKind.Sequential)] public struct BITMAP { public int bmType; public int bmWidth; public int bmHeight; public int bmWidthBytes; public ushort bmPlanes; public ushort bmBitsPixel; public IntPtr bmBits; } [DllImport("gdi32", CharSet = CharSet.Auto, EntryPoint = "GetObject")] public static extern int GetObjectBitmap(IntPtr hObject, int nCount, ref BITMAP lpObject); [DllImport("gdi32.dll")] internal static extern bool DeleteObject(IntPtr hObject); }

  • iPhone - facebook connect on iPhone to get contents of an application's wall?

    - by lostInTransit
    Hi I would like to get the contents of my FB app's wall into my iPhone app. The contents on the wall are directly posted there by me and not obtained from any database. Can someone please point me to the documentation where I can get the information for accessing these messages/their comments from my iPhone app? I searched on the Facebook wiki, but it takes me to the github page for FB-Connect on iPhone, nothing where I can see all the API calls possible. Thanks.

  • Algorithm to calculate the number of divisors of a given number

    - by sker
    What would be the most optimal algorithm (performance-wise) to calculate the number of divisors of a given number? It'll be great if you could provide pseudocode or a link to some example. EDIT: All the answers have been very helpful, thank you. I'm implementing the Sieve of Atkin and then I'm going to use something similar to what Jonathan Leffler indicated. The link posted by Justin Bozonier has further information on what I wanted.

  • Crystal reports .net visual studio 2008 bundled edition

    - by DeveloperChris
    I have a serious issue with crystal reports. when run in my development environment or debugged on my local machine it works fine. but when the application is published to a windows server 2003 it has the dreaded "The report you requested requires further information" Message I have had no luck trying to get rid of this message Anybody know what I can try? DC Here is a bunch more info. I use a placeholder in the aspx page and then set the user/password and database in the codebehind I could not get it to work with a dataset and found that I had to assign odbc connection in the cr designer. and then in the code behind change the above details as required. This is done because the same report can get the data from 3 different databases (live development and training) protected override void Page_Load(object sender, EventArgs e) { base.Page_Load(sender, e); CrystalReportSource1.ReportDocument.Load(Server.MapPath(@"~/Reports/Report5asp.rpt")); CrystalReportViewer1.ReportSource = ConfigureCrystalReports(CrystalReportSource1.ReportDocument,CrystalReportViewer1); // parameters CrystalReportViewer1.ParameterFieldInfo.Clear(); AddParameter("DIid", _app.Data["DIid"], CrystalReportViewer1.ParameterFieldInfo); AddParameter("EEid", _app.Data["EEid"], CrystalReportViewer1.ParameterFieldInfo); AddParameter("CTid", _app.Data["CTid"], CrystalReportViewer1.ParameterFieldInfo); } public ReportDocument ConfigureCrystalReports(ReportDocument report, CrystalReportViewer viewer) { String _connectionString = _app.ConnectionString(); String dsn = _app.DSN(); SqlConnectionStringBuilder SConn = new SqlConnectionStringBuilder(_connectionString); TableLogOnInfos crtableLogoninfos = new TableLogOnInfos(); TableLogOnInfo crtableLogoninfo = new TableLogOnInfo(); ConnectionInfo crConnectionInfo = new ConnectionInfo(); crConnectionInfo.ServerName = dsn;// SConn.DataSource; crConnectionInfo.DatabaseName = SConn.InitialCatalog; crConnectionInfo.UserID = SConn.UserID; crConnectionInfo.Password = SConn.Password; crConnectionInfo.Type = ConnectionInfoType.SQL; crConnectionInfo.IntegratedSecurity = false; foreach (CrystalDecisions.CrystalReports.Engine.Table CrTable in report.Database.Tables) { crtableLogoninfo = CrTable.LogOnInfo; crtableLogoninfo.ConnectionInfo = crConnectionInfo; CrTable.ApplyLogOnInfo(crtableLogoninfo); } return report; } As stated this works fine on my XP machine used for development when deployed on winserver 2003 I get the error DC Some interesting additional information I moved the development to my home machine so I could work on the problem this weekend. So now I am developing debugging and testing on the same machine! In VS2008 I can edit and preview the reports with no problems If I fire up the debugger I can view the reports in the browser with no problems But if I publish the website to another folder on the same machine and fire up IIS and try to browse to a report I get the aforementioned error. All else works as expected. IIS runs under different permissions than VS2008 so perhaps its something to do with that, but I have tried lots of different permissions and cannot get it to run. DC
