• Windows Service Printing Behaviour

  - by Andre

  Alright, I was tasked to develop a Windows Service that listens to a directory for files that are dropped in it, read them, delete them and print out a report. I installed the service on my work laptop (Win 7 x86) and a test machine (XP x86) under a User account at first. It would do everything as it should except the print the report. No errors, nothing. Then I made it run under Local System and it produced a "No printers found" exception. Converting the app to a Console Application and running on these machines gave the desired result. OK, so now I was assuming that there are security "stuff" involved. Then I installed the service on a Server 2008 x64 machine (under Local System) and it just worked. Can anybody explain to me why this is happening? Why does the service allow printing from Server OS but not from a Desktop OS or am I missing something very obvious?

• How to show controls hierarchy in Winform designer

  - by Cédric V

  Hi, One of our client has an old winform application that contains forms with a lot of controls on them. Some of those controls have a deep hierarchy and that make it to hard to select them in the designer. I would need to understand this hierarchy to make modification and correct some bugs, is there a tools, plugin or something to be able to clearly see this hierarchy ? Something like in the aspx source when you have a breadcrumb of where you are in the HTML hierarchy (HTML Body div etc ...) or something more visual maybe ? Any ideas ? PS : we use Visual Studio 2008, .NET 2.0

• Is it possible to manipulate the format on a DataGridView that is bound to a Data Source?

  - by Jack Johnstone

  I´m using SQL Server 2005 and Visual Studio 2008, C#. In the data source (the SQL Server data table) I use the date format mm/dd/yyyy, however, in a forms overview (DataGridView) users would like to see a completely other format, with year, week number and day number of week (yyww,d). I´ve created an algorithm for this transformation, but can I populate the affected cells with yyww,d instead of mm/dd/yyyy? And in that case - how would I do it? I guess I need to do it after the cells are populated, but before they are shown. The generic question is - how do I manipulate the format of Data Source bound DataGridView cells.

• How do you add < or > to a summary tag in Visual studio?

  - by Tony

  How do you add < (less than) or (greater than) to a summary comment in visual studio? I am in Visual Studio 2008. I have a generic method: public bool IsMemberProtected<T>(Expression<Func<T, object>> expression) Would love to have a summary tag of something like this /// <summary> /// Determines whether a member is protected. /// /// Usage: IsMemberProtected<ExampleType>(x => x.Member) /// </summary> But when I do that, the tooltip for the property no longer works when a developer hovers over the method in code to view the summary tag. Thoughts?

• When does the DataContext will open a connection to the DB?

  - by Eran Betzalel

  I am using L2S to access my MSSQL 2008 Express server. I would like to know when the DataContext will open a connection to the DB? and will it close the connection right after it opened it? For example: var dc = new TestDB(); // connection opened and closed? dc.SomeTable.InsertOnSubmit(obj); // connection opened and closed? foreach(var obj in dc.SomeTable.AsEnumerable()) // connection opened and closed? { ... // connection opened and closed? } dc.SubmitChanges(); // connection opened and closed?

• Help, I need to debug my BrowserHelperObject (BHO) (in C++) after a internet explorer 8 crash in Rel

  - by BHOdevelopper

  Hi, here is the situation, i'm developping a Browser Helper Object (BHO) in C++ with Visual Studio 2008, and i learned that the memory wasn't managed the same way in Debug mode than in Release mode. So when i run my BHO in debug mode, internet explorer 8 works just fine and i got no erros at all, the browser stays alive forever, but as soon as i compile it in release mode, i got no errors, no message, nothing, but after 5 minutes i can see through the task manager that internet explorer instances are just eating memory and then the browser just stop responding every time. Please, I really need some hint on how to get a feedback on what could be the error. I heard that, often it was happening because of memory mismanagement. I need a software that just grab a memory dump or something when iexplorer crashes to help me find the problem. Any help is appreciated, I'll be looking for responses every single days, thank you.

• How do I make a project built into a downloadable Cd?

  - by Dcurvez

  hi all I just got finished making my first project in visual studio 2008. what I want to do is put it on a CD and let another person run it. I went to the clean and build and publish and all went well. When I took it to my friends house to put it on her computer..i never got a "download" and "install" screen. We were able to see it and use it on her computer (which is good cuz she doesnt have Visual on her machine) but I wanted her to be able to use it without keeping the CD in the drive. Is there some setup or something I have to do to make my program download and install? The whole shibang was all done with starting a new windows application..and then just adding windows forms to the original. Thanks :)

• How can I get all the .pdb files in the same folder?

  - by uvts_cvs

  I have a solution in Visual Studio 2008, it has dozens of projects. I would like to have all the pdb in the same folder. From the property page of a project I see that the pdb will go to the "Intermediate Directory"; also .obj files go to the "Intermediate Directory". Each of our projects has its own folder because we want to keep the .obj separated, at the same time I would like to have all the pdb in the same folder. Looking at the buildlog.htm I see the option /PDB which controls the pdb path, this option doesn't seem to me available in the property page. Maybe I will have to use a post buil script?

• casting odd smallint time to to datetime format.

  - by c6400sc

  Hello everyone, I'm working with a db (SQL server 2008), and have an interesting issue with times stored in the db. The DBA who originally set it up was crafty and stored scheduled times as smallints in 12-hour form-- 6:00AM would be represented as 600. I've figured out how to split them into hours and minutes like thus: select floor(time/100) as hr, right(time, 2) as min from table; What I want to do is compare these scheduled times to actual times, which are stored in the proper datetime format. Ideally, I would do this with two datetime fields and use datediff() between them, but this would require converting the smallint time into a datetime, which I can't figure out. Does anyone have suggestions on how to do this? Thanks in advance.

• References/walkthroughs for maintaining database schemas with Visual Studio 2010?

  - by user206356

  I have Visual Studio 2010 Beta 2 and SQL Server 2008 installed. I'm working with a populated database and want to modify various column types. SQL Server Management Studio requires me to drop tables to do this, and get pretty finicky given my moderate level of knowledge of SQL Server. However, I heard the new database project type supports changing the database schema to the desired format and it will handle creating and running all the scripts to implement the changes. I've created a VS2010 database project using the existing database as the source, but so far haven't had much luck figuring out the appropriate method to make the changes without getting an error. As a result, I'm looking for any reference info I can find on using VS2010's capabilities in this area. Any suggestions?

• Project-wide additional library paths -- MSVS2008

  - by sacamano

  Hi there. I'm setting up a VC++ project in MS Visual Studio 2008 that'll be used by several people. I wanted to keep things as simple as possible so I've set up Additional Include Directories via the Project properties. I've also set up additional library files via Tools - Options - Projects and Solutions - VC++ Directories. However, my issue is that I really need to set up Additional library PATHs, because I am using an SDK which does inline linking of libraries. I could just tell each one of the participants to manually add the library path to their MSVS2008 environment, but it would be handy if I could integrate the RELATIVE library path in the project itself.

• How do stream rows from a MSSQL table into a .NET app, in 10000 row chunks?

  - by Gravitas

  I have a table with 300 million rows in Microsoft SQL Server 2008 R2. There is a clustered index on the date column [DataDate] which means that the entire table is ordered by the date column. How do I stream out the data from this table, into my .NET application, in 10000 row chunks? Environment: Using C#. Have to be able to pause the data stream at any point, to allow the client to process the rows. Unfortunately, cannot use a select * from as this will select the entire table (its 50GB - it won't fit into memory).

• Database design: one huge table or separate tables?

  - by littlegreen

  Currently I am designing a database for use in our company. We are using SQL Server 2008. The database will hold data gathered from several customers. The goal of the database is to acquire aggregate benchmark numbers over several customers. Recently, I have become worried with the fact that one table in particular will be getting very big. Each customer has approximately 20.000.000 rows of data, and there will soon be 30 customers in the database (if not more). A lot of queries will be done on this table. I am already noticing performance issues and users being temporarily locked out. My question, will we be able to handle this table in the future, or is it better to split this table up into smaller tables for each customer?

Is there any way to publish this project ?

• how to turn visual studio windows forms project into an application?

  - by Pieter888

  Hey everyone, I programmed an hour-sheet application and now I would like to publish it so people can install and run it. I've tried the publish function of visual studio 2008 but this gives me a clickOnce application/installer that's really confusing, but it works when I run it, but when I export the installer to another pc it installs it crashes at the end of the install. so I tried just coping the installed files but then the program crashes at startup. Is there a simple way to compile the application to a simple standalone executable or maybe containing a separate folder containing the resources (images/classes)?

• deep zoom is not displayed

  - by George2

  I am using VSTS 2008 + C# + .Net 3.5 + Windows Vista Enterprise x86. I have used Silverlight Deep Zoom composer tool to export my composed images into Siverlight type. Everything is previewed fine after export successful message (I select browse from browser). But when I click the Test.html in the exported project to show Deep Zoom effects from browser, nothing is displayed. Here is my screen snapshot. Any ideas what is wrong? http://i41.tinypic.com/2dac561.jpg EDIT 1: to my surprise, there is no clientbin folder in my exported project. I have made two screen snapshots for, my project folder generated by Deep Zoom Composer under Exported Data folder; the content of GeneratedImages folder under my project folder. Please refers them to, http://i42.tinypic.com/346ncec.jpg http://i42.tinypic.com/15zqkn9.jpg Any ideas what is wrong? thanks in advance, George

• auto_inline - inadequate documentation

  - by Mick

  I want to disable inlining for a particular function. What the compiler does for everything else should be as specified in the project properties. I found a page on a forum which suggested the following: #pragma auto_inline(off) void func() { } #pragma auto_inline() The author suggested that calling auto_inline() with no arguments will set the compiler to revert to doing whatever the default action was before the call to auto_inline(off). Can anyone confirm that this works for visual studio 2008? I ask because the VS2008 documentation makes no mention at all of what happens if you call this function with no arguments.

• Single logical SQL Server possible from multiple physical servers?

  - by TuffyIsHere

  Hi, With Microsoft SQL Server 2005, is it possible to combine the processing power of multiple physical servers into a single logical sql server? Is it possible on SQL Server 2008? I'm thinking, if the database files were located on a SAN and somehow one of the sql servers acted as a kind of master, then processing could be spread out over multiple physical servers, for instance even allowing simultaneous updates where there was no overlap, and in the case of read-only queries on unlocked tables no limit. We have an application that is limited by the speed of our sql server, and probably stuck with server 2005 for now. Is the only option to get a single more powerful physical server? Sorry I'm not an expert, I'm not sure if the question is a stupid one. TIA

• Add Unique Key For Nullable Columns - SQL Server

  - by Ruby

  I'm using sql server 2008 R2 and would like to apply unique key constraint to nullable columns. This code works good, but if I have multiple columns to add this rule to, it would generate as many 'nullbuster' columns. ALTER TABLE tblBranch ADD nullbuster AS (CASE WHEN column1 IS NULL THEN BranchID ELSE NULL END); CREATE UNIQUE INDEX UK_Column1 ON tblBranch(column1,nullbuster); tblBranch is the table name, nullbuster would be the new column name, BranchId is the Primary key column of the target table, and Column1 is the column name of the target column. Is there any way that I could achieve the goal without generating new columns.

• How to use the merge command

  - by Vaccano

  Say I have a table called Employee (has ID, NAME, ADDRESS, and PHONE columns). (Not my real problem, but simplified to make the question easier.) If I call a sproc called UpdateEmployee and I pass in a @Name, @Address, @Phone and @ID. Can merge be used to easily check to see if the ID exists? If it does to update the name, address and phone? and if it does not to insert them? I see examples on the net, but they are huge and hairy. I would like a nice simple example if possible. (We recently upgraded to SQL 2008, so I am new to the merge command.)

• Why Resource (.resx) file added on merely changing Form size and on adding button which is not resou

  - by Muhammad Kashif Nadeem

  1- Resource files suppose to be added on adding some resource in application like image or audio or video etc. But if I just change size of form a .resx file under that particular form. Changing size of form does not add any resource so why this .resx file. 2- I dropped a button on form and a resource file is included again this button is not some kind of resource, it is object created and having information in designer file. 3- A resource file added on dropping button on form but if I delete this resource file and run application it compile and run with NO error and button is still there. If this button has any relation with resource file then there must by some kind of compile or runtime error AND if .resx file has nothing to do with button then why it was added? I am using VS 2008. Thanks in advance for the help

• How to map a virtual directory to a website in VS?

  - by salvationishere

  I am developing a C# VS 2008 website, trying to add a Master file. I created a virtual directory in IIS housing the "Master" folder, containing the Master files. Now how do I reference these files from my website in VS? One problem is I do not know where I need to publish this Master folder to. Other problem is I do not know how to reference this Master file in my aspx Page directive. FYI, this master folder is physically located outside of c:\inetpub\ in a totally separate file location. Is this a problem?

• Can you have a web application project produce multiple DLLS?

  - by chris

  I have a VS 2008 web application project that is getting large. My structure looks like: - WebRoot - Common/ - Foo/ - Bar/ - Baz/ so I end up with a single Webroot.dll that contains the code for common, foo, bar, and baz. Is it possible to set it so that I end up with common/ in webroot.dll, and code in foo ends up in foo.dll, bar in bar.dll, etc? Update: A couple of suggestions to move some stuff into class libraries. We already have a dozen or so separate class library projects as part of the solution; Foo, Bar and Baz contain nothing but web forms and the associated code-behinds, so moving them into separate class library projects is not feasible.

• Easy plugin or procedure for sqlserver Management Studio to script row inserts.

  - by Patrick Karcher

  I've never been able to find a good script or plugin for sql server Management Studio (2005 and or 2008) for a very common scripting need: specifying a few/all rows in a table and scripting their insert. You can guess my story: I've got some configuration data in my dev db and I need to script it for deployment to UAT and then production. I've found a few cludgy systems in the past, that were more trouble than they were worth. I need something free and unobtrusive. Once I find it I'll share it with the other 20 developers in my shop who are annoyed by this. Aren't we all annoyed by this by the way? What is the best, easiest, free, way to specify a few/all rows in a table and get a script their insert?
