  • Project works in eclipse but not when exported

    - by Mike
    I wrote an application that uses GraphViz to generate some graphs as .gif's according to the DOT syntax. When I run from Eclipse the images are generated fine but when I export it as a jar the images are created but there is no data in them. When I view them in Microsoft Picture Viewer its just the red X. It was working as an exported jar until I put the picture generation in its own thread. I can't seem to figure out whats going on here. Are there any problems exporting multi-threaded projects? Any one have any ideas? Thanks

  • asp.net impersonation identity: Where does it come from?

    - by Rising Star
    Here's a simple question I've been stuck on for a while. When I set < identity impersonate=true > in my web.config so that asp.net impersonates the logged on user automatically (or the anonymous account if not using Windows Authentication), where does the identity that asp.net impersonates come from? This document: http://msdn.microsoft.com/en-us/library/ff649264.aspx shows three places you can retrieve information about the logged on user: Httpcontext.Current.user System.Threading.Thread.Current System.Security.Principal.WindowsIdentity.GetCurrent It seems that none of these locations consistently match the identity that gets impersonated when I set < identity impersonate=true > in web.config. I would like to know where the impersonated identity comes from.

  • Python as your main language. Possible?

    - by Deinumite
    I am currently attending college and the languages that I will 'know' by graduation are C++ and Java. That being said, i am also in the process of teaching myself Python. I know that every programming language has its own pros and cons, but would it be possible to become a python developer out of school? I always have more 'fun' programming in Python than i do in C++ or Java, and I am also in love with Pythons documentation. I know C++ will always be on top in terms of speed, but what would be the benefit of memorizing every javadoc against focusing on Python instead? are there good jobs to be had with Python? edit: also, would it be beneficial for me to look at C# as well? Microsoft is really throwing their support at it so that could be a decent career path as well.

  • How to set PATH to another variable value with spaces in Windows batch file

    - by Evgeny
    I've got a Windows batch script issue that I'm bashing my head against (no pun intended). The problematic script looks like this: if defined _OLD_VIRTUAL_PATH ( set PATH=%_OLD_VIRTUAL_PATH% ) When I run it and _OLD_VIRTUAL_PATH is set I get: \Microsoft was unexpected at this time. _OLD_VIRTUAL_PATH is a variable that was originally set from PATH and it contains spaces - I'm pretty sure that's the problem. But what's the solution? It runs successfully if I enclose it in quotes, but I don't think the entire value of the PATH variable is supposed to be in quotes.

  • SQL Server 2008 Management Studio Activity Monitor

    - by Angelo
    Hi, I tried to turn on the Activity Monitor using SQL Server 2008 Management Studio (SSMS) through the options window of the application (Tools | Options | Environment | General | At Startup). I restarted SSMS and I am getting the following message: "This operation does not support connections to Microsoft SQL Server Standard Edition version 8.00.2249." I need to be able to monitor the processes and activities inside the database since I am investigating a particular application which takes a lot of time in its database data retrieval access and I am thinking it may be due to some locks or some processes. How do I resolve this? Inputs highly appreciated. Thanks.

  • Passing report values to a query

    - by Beavis
    I'm a novice with Microsoft Access as my background is mostly .NET. I'm sure what I'm trying to accomplish is dead simple but I need some direction. I have a report and a query. The query returns a single numeric value based on a single numeric criteria. Select total from table where id = [topic] I have placed a text box on my report so I can feed the id to this query and in return get the total. It seems like DLookUp is what I want but no matter how I construct it, I get an "#Error" in the text box when I run the report. Currently my DLookUp looks like this (I just hard-coded now for simplicity): =DLookUp("[total]","myquery","[topic] = 3") How can I pass a value from a field on my report to a query so I can return the query's single numeric value? Thanks.

  • Python Regular Expression TypeError

    I am writing my first python program and I am running into a problem with regex.

For example if I make the following changes regex doesn't complain: v = re.compile(r"(?i)DisplayName") if v.search(name): Thanks for any help.

  • Localizing formatting functions instead of properties in VS.NET resources

    - by LexL
    I noticed that .NET framework uses formatting functions, generated the same way localizable string are. There is a resource file Resources.resx with resource string TestString. So you may use it in code like this: string localizableValue = Resources.TestString; Now, imagine you need a formattable localizable string, to use it in string.Format function. So everytime you use it, you have to write something like this: string localizableFormattedValue = string.Format(Resources.TestFormatString, someParam1, someParam2); The observation says that in .NET framework generated resource classes already include the above construction. So instead of string property, a string function is generated. The resulting code looks like this: string localizableFormattedValue = Resources.TestFormatString(someParam1, someParam2); The question is - how do they do this? Is it some custom Microsoft feature (resx generator) or I'm missing something obvious?

  • AJAX Problem - No response text in FireFox, but ok in IE

    - by Taiba
    Hi, I am making a simple AJAX call to an external site. It works ok in IE, but in Firefox, not response text is returned. I think it might have something to do with the response being "chunked", but I'm not sure. Any ideas? Thanks. function loadXMLDoc() { var xmlhttp; var urlString = "http://drc.edeliver.com.au/ratecalc.asp?Pickup_Postcode=6025&Destination_Postcode=6055&Country=AU&Weight=100&Service_Type=STANDARD&Length=100&Width=100&Height=100&Quantity=2"; if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); } else {// code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4) { window.alert(xmlhttp.responseText); } } xmlhttp.open("GET", urlString, true); xmlhttp.send(); }

  • Why operator= returns reference not const reference

    - by outmind
    The original question is related to overloading operator= and I like to share my findings as it was nontrivial for me to find them. I cannot imagine reasonable example to use (a=b) as lvalue. With the help of IRC and google I've found the next article: http://msdn.microsoft.com/en-us/magazine/cc301415.aspx it provides two examples. (a=b)=c f(T& ); f(a=b) but both a bit not good, as first violate associativity and I believe that it is bad practice. The second one give me the same feeling. Could you provide more good examples why it should be non constant?

  • Firing events in script task

    - by Anonymouslemming
    I've got an SSIS project where I am constructing an SQL command based on some variables. I'm constructing the command in a script task, and want to output the constructed SQL to the 'Execution Results' window. I am trying to do this using a FireInformation line from inside my script as follows: Dts.Events.FireInformation(99, "test", "Make this event appear!", "", 0, true); However, in the script editor when editing ScriptMain.cs, that line is underlined in red, and on mouseover, I get the following message: Error: The best overloaded method match for 'Microsoft.SqlServer.Dts.Tasks.ScriptTask.EventsObjectWrapper.FireInformation(int, string, string, string, int, ref bool') has some invalid arguments As a result, my script does not compile and I cannot execute it. Any idea what I'm doing wrong here, or what I need to change to be able to see the values of my variables at this point in the Execution output?

  • Make SharePoint 2007 List View read-only

    - by FireSnake
    I need to deploy a new List View for the standard List View Web Part in MOSS 2007 via the object model (the list already exists, a new view should be added). I need and want to make this list view read-only. This is because saving changes to the view would corrupt modifications made to Header/Footer. How can I do that via the object model? I looked at the content db, the read-only flag (0x20) is stored with the view and could technically be updated using calls to proc_GetAllWebPartsOnPage and proc_UpdateView[Properties]. NOTE: The database interface and all mentioned stored procs are all documented by Microsoft. Is there ANY way to do that via the object model, because I would strongly prefer that?

  • Use registry to startup a program, and also change the current working directory?

    - by Joel
    I am trying to start a program I made in this directory: C:\example\example.exe -someargument when the computer starts up. I am attempting to use this registry key: HKEY_LOCAL_MACHINE/Software/Microsoft/Windows/CurrentVersion/Run with the key being: Name: example Type: REG_SZ Data: "C:\example\example.exe -someargument" But my program also needs files from the directory C:\example but can't find them since the current working directory is different. Is is possible to do something like this in the registry key value "cd C:\example\; example.exe -someargument" so that it will change the directory? Or is there a better solution? Thanks!

  • C++ open() fails for no apparant reason

What could possibly be the cause for this? I'm using Microsoft Visual C++. When I hardcoded the filename as a constant it instead ended up garbled: http://pici.se/pictures/CNQEnwhgo.png Suggestions?

  • Is there a tool that will show diagrams of my SQL database in real-time?

    - by Rising Star
    I've created some diagrams of SQL tables using the "Reverse Engineer" feature of Microsoft Office Visio. I like being able to visualize my relational databases in this manner. However, what I get is just a static document that I can print, e-mail to colleagues, and click widgets on. Earlier this year, I saw at a demo that the new version of Visual Studio 2010 has a new feature called the "Architect Explorer", which allows developers to view relationships among .net classes on the fly. It has many features for filtering the data that the developer is interested in. It would be really awesome if I could visually browse my tables and stored procedures and see what is related to what by primary key, foreign key, and referenced in stored procedures. I realize that I'm talking about two entirely different technologies and it's not a perfect analogy, but is there some similar tool that would allow me to visualize tables in my SQL database?

  • Dates that intersect

    - by MikeAbyss
    Hi everyone, I've been researching this problem for awhile now and I can't seem to come to a solution, hopefully someone here can help. Currently I'm working with Microsoft SQL server management, I've been trying to do the following: Previously, the old query would just return the results that fit between two dates Heres the previous query: SELECT e.Name, o.StartDate, o.EndDate FROM dbo.Name e, dbo.Date o WHERE where e.Name = o.Name and o.StartDate <= '2010-09-28 23:59:59' and o.EndDate >= '2010-9-28 00:00:00' and e.Name like 'A' Example table that is produced after the query runs (The real table has a lot more rows obviously :P) : Name Start End A 2010-09-28 07:00:00 2010-09-28 17:00:00 A 2010-09-28 13:45:00 2010-09-28 18:00:00 A 2010-09-28 08:00:00 2010-09-28 16:00:00 A 2010-09-28 07:00:00 2010-09-28 15:30:00 However we need to change this, so that the query does the following: find the dates that intersect for a day x find the dates that don't intersect for a day x I've found a real useful site regarding this http://bloggingabout.net/blogs/egiardina/archive/2008/01/30/check-intersection-of-two-date-ranges-in-sql.aspx However the date to compare against is inputted, mine on the other hand has to all dates that intersect/don't intersect. Thanks for the help everyone.

  • Forms Authentication Across Applications Stopped Working

    - by colleski
    Hi, I have a .net 1.1 ASP application (domain.com) which has a .net 2 virtual directory (domain.com/v2) beneath it, both applications run within their own app pool on the same machine running IIS 6. The web.config files for both apps are setup for Forms Authentication as described here - http://msdn.microsoft.com/en-us/library/eb0zx8fc(v=VS.80).aspx. Users would be directed to the domain.com/v2/login.aspx page which would authenticate for both applications, this configuration has been working fine for the last few years until installing one of the recent Windows 2003 security updates today. Now after authenticating under /v2 users keep getting redirected back to domain.com/v2/Login.aspx as domain.com doesnt see them as authenticated anymore. Any ideas as to which security update would have caused this and if its possible to rollback? I've looked at a few suggestions on this (e.g. Cross app on subdomain form authentication not working) and other sites but no luck so far Any help would be appreciated. Thanks

  • FastObjects.NET(is an OODB from Versant) performence in Real Scenerios?

    - by Lalit
    FastObjects.NET Saves the whole class object(if marked with attribute Persistent) at once in file system(using serilization or similar technology). They are promissing that it is even faster then normal SQL DB approach. My team also thought it is better and faster to save the whole object once instead of each field one by one. Defination of their website: FastObjects .NET 10.0 fully conforms to the Microsoft.NET 2.0 framework. Tightly integrated with Visual Studio 2005, it offers a developer-friendly, object-oriented alternative to a relational database for .NET persistence. I want to have your experiences of using FastObjects in production scenerio? They are promising for Indexing/Transaction/clustoring/replication.

  • How to tell my asp.net page to use .net 3.5?

    - by kralco626
    My company recently upgraded from IE 6 to IE 8. My site does not render properly. I wanted to make sure my .net version was fixed before I started to try to fix a problem. I think my web.config file says i'm using 3.5, but if I get an error when running the app I get this: Version Information: Microsoft .NET Framework Version:2.0.50727.3603; ASP.NET Version:2.0.50727.3082 Why does it say 2.0? rather than 3.5? How do i change this? (using visual studio 2008, running the site locally) Thanks in advance!

  • Parsing C# code to evaluate expressions (basically, implementing Intellisense)

    - by halivingston
    I'm trying to evaluate C# code as it gets typed, think of it as if I'm trying to write an IDE. So a person types code, I want to find out what code did he just write: String x = ""; I want to now register that x is a type of String. And now everytime the user types x again, and I want to show him all the things he can do with x, basically like Visual Studio Intellisense. Will I need some lexers or parsers for this? Will that make it easier? I've heard VS 2010 has some features around this that Microsoft has released. Any ideas?
