• Why does the .NET tab in the 'Add Reference' dialog in Visual Studio not list the contents of the GA

  - by abroun

  Duplicate of: Getting assemblies to show in the .NET tab of Add Reference So, I'm using Visual C# 2008 Express Edition and I've just been on a bit of a detour as I found out that my assumption that the .NET tab of the 'Add Reference' dialog lists the contents of the GAC was incorrect. This was a bit of a problem for me as the assembly that I wanted to reference from my project was only available in the GAC. (It was Microsoft.XNA.Framework v2.0 obtained from the XNA 2.0 redistributalbe and as far as I could see it installed only into the GAC). I worked round the problem by setting the reference to Microsoft.XNA.Framework manually in the .csproj file and then getting a copy of the dll out of the cache. I was then able to create a directory for the DLL, add it to Visual Studio's list of assembly directories in the registry and then voila! I could see it in the .NET tab. This all seems like a bit of a faff to me and I don't think that my initial assumption (that the .NET tab shows the contents of the GAC) was that unreasonable or would be that uncommon. Can someone who knows more than me tell me why the contents of the GAC aren't shown? The documentation just says that they are not, but is there a good reason? is there actually a way to get the entire contents of the GAC to be listed? A tick box I've missed somewhere? Any info much appreciated.

• Why won't VS2010 RC use my existing types when I add a service reference?

  - by Johan Driessen

  I have a huge problem getting services references in VS2010 RC to use existing assemblies. Even though I have a class library with all the data contracts (classes marked with DataContract and properties with DataMember) that is shared between the service project and the consuming project (which is a class library), when I add a service reference, the data contracts are regenerated withing the service reference instead of using the existing types. When I was using VS2010 beta 2, this worked fine, and I have existing service references using the very same data contracts. But if I add a new service reference, or even update an old one, it won't use the existing types anymore. I have made a mini-test-solution, with one service, one data contract type and one console app as a consumer (all in the same solution), and there it seems to work, but that's no great comfort to me. Is there any way to see why it can't use the existing types? Edit to clearify. It works to generate the proxy classes with svcutil.exe, and point to the data contracts dll, like this: svcutil.exe http://localhost/MyService.svc /reference:[Path To DataContracts]\DataContracts.dll /n:*,MyProject.MyServiceReference /ct:System.Collections.Generic.List`1 The question is, what possible reason could there be for Visual Studio to generate its own datacontracts instead of using the existing ones even though the "reuse" checkbox is checked and the datacontracts assembly is referenced.

• Oracle - Getting Select Count(*) from ... as an output parameter in System.Data.OracleClient

  - by cbeuker

  Greetings all, I have a question. I am trying to build a parametrized query to get me the number of rows from a table in Oracle. Rather simple. However I am an Oracle newbie.. I know in SQL Server you can do something like: Select @outputVariable = count(*) from sometable where name = @SomeOtherVariable and then you can set up an Output parameter in the System.Data.SqlClient to get the @outputVariable. Thinking that one should be able to do this in Oracle as well, I have the following query Select count(*) into :theCount from sometable where name = :SomeValue I set up my oracle parameters (using System.Data.OracleClient - yes I know it will be deprecated in .Net 4 - but that's what I am working with for now) as follows IDbCommand command = new OracleCommand(); command.CommandText = "Select count(*) into :theCount from sometable where name = :SomeValue"); command.CommandType = CommandType.Text; OracleParameter parameterTheCount = new OracleParameter(":theCount ", OracleType.Number); parameterTheCount .Direction = ParameterDirection.Output; command.Parameters.Add(parameterTheCount ); OracleParameter parameterSomeValue = new OracleParameter(":SomeValue", OracleType.VarChar, 40); parameterSomeValue .Direction = ParameterDirection.Input; parameterSomeValue .Value = "TheValueToLookFor"; command.Parameters.Add(parameterSomeValue ); command.Connection = myconnectionObject; command.ExecuteNonQuery(); int theCount = (int)parameterTheCount.Value; At which point I was hoping the count would be in the parameter parameterTheCount that I could readily access. I keep getting the error ora-01036 which http://ora-01036.ora-code.com tells me to check my binding in the sql statement. Am I messing something up in the SQL statement? Am I missing something simple elsewhere? I could just use command.ExecuteScaler() as I am only getting one item, and am probably going to end up using that, but at this point, curiosity has got the better of me. What if I had two parameters I wanted back from my query (ie: select max(ColA), min(ColB) into :max, :min.....) Thanks..

• What's the "proper" way to retrieve a reference to a ribbon object?

  - by Nick

  For a VSTO workbook project, is there a best practice for retrieving a reference to the Ribbon object from the ThisWorkbook class? Here's what I'm doing: In my Ribbon class, I created a public method called InvalidateControl(string controlID). I need to call that method from the ThisWorkbook class based on when a certain workbook level event fires. But the only way I can see to "get" a reference to that Ribbon object is to do this... // This is all in the ThisWorkbook class Ribbon ribbon; protected override IRibbonExtensibility CreateRibbonExtensibilityObject() { this.ribbon = new Ribbon(); return this.ribbon; } ...which seems a little smelly. I mean, I have to override CreateRibbonExtensibilityObject() regardless; all I'm doing beyond that is maintaining a local reference to the ribbon so I can call methods against it. But it doesn't feel right. Is there another, better way to get that reference in the ThisWorkbook class? Or is this pretty acceptable? Thanks!

• Using excel, how can I count the number of cells in a column containing the text "true" or "false"?

  - by Jay Elston

  I have a spreadsheet that has a column of cells where each cell contains a single word. I would like to count the occurrences of some words. I can use the COUNTIF function for most words, but if the word is "true" or "false", I get 0. A B 1 apples 2 2 true 0 3 false 0 4 oranges 1 5 apples In the above spreadsheet table, I have these formulas in cells B1, B2, B3 and B4: =COUNTIF(A1:A5,"apples") =COUNTIF(A1:A5,"true") =COUNTIF(A1:A5,"false") =COUNTIF(A1:A5,"oranges) As you can see, I can count apples, but not true or false. I have also tried this: =COUNTIF(A1:A5,TRUE) But that does not work either. Note -- I am using Excel 2007.

• How do I reference the value of a constructed environment variable in a loop?

  - by Rob Spieldenner

  What I'm trying to do is loop over environment variables. I have a number of installs that change and each install has 3 IPs to push files to and run scripts on, and I want to automate this as much as possible (so that I only have to modify a file that I'll source with the environment variables). The following is a simplified version that once I figure out I can solve my problem. So given in my.props: COUNT=2 A_0=foo B_0=bar A_1=fizz B_1=buzz I want to fill in the for loop in the following script #!/bin/bash . <path>/my.props for ((i=0; i < COUNT; i++)) do <script here> done So that I can get the values from the environment variables. Like the following(but that actually work): echo $A_$i $B_$i or A=A_$i B=B_$i echo $A $B returns foo bar then fizz buzz

• Count the Number of Characters in a Full FIle Path?

  - by Richie086

  I need to be able to count the number of characters in a full path to a file in windows. How I am currently accomplishing this task is as follows: Open a command prompt cd to the directory in question (for example c:\CruiseControl\ProjectArtifacts\ProjectName) type the following command dir /s /b output.csv Open the resulting output.csv file in excel. use the =LEN() function in excel to count the number of characters per row as listed in the output.csv file. Does anyone know of an explorer shell extension, or some 3rd party tool that could preform this function without me having to manipulate the output from dir in excel? Is there some easier way to go about doing this? The root of the issue I am having is the ~260 character file path limit in Windows. I am trying to analyze which paths are approx ~260 characters so I can shorten them to avoid getting this error.

• TFS Build Server not finding 'Microsoft.Expression.Interactions&rsquo;

  - by Chris Skardon

  We’ve been trying to get the build server to pick up the Microsoft.Expression.Interactions.dll needed so we can use things like the ExtendedVisualStateManager and the DataStateBehavior. Adding the DataStateBehavior in Blend adds the reference to the project, so it all compiles fine on the local machine. Checking in the code into a CI server throws up some ugliness: d:\Builds\6\Source\MyFile.xaml (290): The tag 'DataStateBehavior' does not exist in XML namespace 'http://schemas.microsoft.com/expression/2010/interactions'. Errr, it should do…?? The reference is there, so… ahhhhh! A quick check of the properties and we’re using the dll from the c:\program files (x86)\ location, no wonder the build server can’t find it – let’s add the dll into our (ever expanding) ‘lib’ folder, reference that version, and check that bad boy in… No. Still No. Still get the same error. What the??? The reference is still pointing to the program files location?? Ok, so let’s modify the csproj file using the wonderful notepad, changing the reference from <Reference Include="Microsoft.Expression.Interactions, /* loadsa shizzle here */ /> to <Reference Include="Microsoft.Expression.Interactions">     <HintPath>..\Lib\Microsoft.Expression.Interactions.dll</HintPath> </Reference> Check that in, aaaand… Success!!! The reason for this (from what I can gather from here) is that we’re using the Productivity Power Tools, and they try to be clever about referencing dlls, and changed what we’d asked (i.e. for the local version) to use the original program files location.. Editing the file in notepad (sweet sweet notepad) gets around this issue… Irritating, took a while to figure this out… Meh :)

• Reference custom list form fields from code behind and automatically fill them with values.

  - by Janis Veinbergs

  Hello. I`v made my custom NewForm.aspx for my list and I want to add some custom code to it. So I inherit that form from my own class: public class MyCustomNewForm : Microsoft.SharePoint.WebPartPages.WebPartPage Now I want to reference some of available fields to automatically fill them for user. (Javascript won't help here as I have to get some data from other lists). But I have no idea how do I reference these fields from codebehind files. The code for control field is written (well, it was generated by Sharepoint Designer when using command Insert SharePoint Controls Custom List Form...) in .aspx page like this: <SharePoint:FormField runat="server" id="ff1{$Pos}" ControlMode="New" FieldName="Title" __designer:bind="{ddwrt:DataBind('i',concat('ff1',$Pos),'Value','ValueChanged','ID',ddwrt:EscapeDelims(string(@ID)),'@Title')}"/> When looking at id at runtime, it is insanely long So how do i reference fields, so I could set Text property on them in my codebehind file?

• count of distinct acyclic paths from A[a,b] to A[c,d]?

  - by Sorush Rabiee

  I'm writing a sokoban solver for fun and practice, it uses a simple algorithm (something like BFS with a bit of difference). now i want to estimate its running time ( O and omega). but need to know how to calculate count of acyclic paths from a vertex to another in a network. actually I want an expression that calculates count of valid paths, between two vertices of a m*n matrix of vertices. a valid path: visits each vertex 0 or one times. have no circuits for example this is a valid path: but this is not: What is needed is a method to find count of all acyclic paths between the two vertices a and b. comments on solving methods and tricks are welcomed.

• How to suppress a group header based on running-count results?

  - by Sarah

  Hi I'm trying to suppress a group header when there are no detailed results in another following group. I have added a manual running count total which is showing correct numbers (such as 0 when no records show on the report). I've taken this approach since I have various items suppressed within the detailed section and don't want them as part of the count. I'm trying to say in the header not to shown the header if there are no corresponding records showing in the detailed section. But, it's not working. When I say suppress if the display count is 0, it suppresses all of the headers instead of just the ones that need to be displayed. HOW CAN I FIX THIS? THANKS... Sarah

• Hash Table: Should I increase the element count on collisions?

  - by Nazgulled

  Hi, Right now my hash tables count the number of every element inserted into the hash table. I use this count, with the total hash table size, to calculate the load factor and when it reaches like 70%, I rehash it. I was thinking that maybe I should only count the inserted elements with fills an empty slot instead of all of them. Cause the collision method I'm using is separate chaining. The factor load keeps increasing but if there can be a few collisions leaving lots of empty slots on the hash table. You are probably thinking that if I have that many collisions, maybe I'm not using the best hashing method. But that's not the point, I'm using one of the know hashing algorithms out there, I tested 3 of them on my sample data and selected the one who produced less collisions. My question still remains. Should I keep counting every element inserted, or just the ones that fill an empty slot in the Hash Table?

• How do I do a where clause in sql and return a count back?

  - by chobo2

  Hi I am using mssql and I want to make a query that returns a count back with a where clause. Like say I have a product Table ProductId ProductName Active So how would I make it I have like Select Count(*) From Product now I don't know how to filter it so it only could if Active = true; So if there are 3 active products then it would return a count of 3 even if there is a hundred rows in the db and the other 97 are only not active. so the where clause would be probably like where active = true I am not sure how to put them together though.

• How to add reference an assembly that is not in the GAC from a t4mvc template (.tt)

  - by stephen

  I have found the place near the very top in a T4MVC template file (.tt) where assembly references can be added, which looks like: <#@ assembly name="System.Core" #> <#@ import namespace="System.Collections.Generic" #> However, it seems that I can only reference assemblies that are in the GAC. i.e. if I have an assembly MyProject.Stuff.dll (not in the GAC) added as a reference to the VS project containing the template then I expected to be able to add something like the following: <#@ assembly name="MyProject.Stuff" #> <#@ import namespace="MyProject.Stuff" #> If I do this then I get the following error: Error 1 Compiling transformation: Metadata file 'MyProject.Stuff' could not be found C:\Work\Development\DotNetSolution\MyProject\Utils\T4MVC\T4MVC.tt 1 1 How can I add a reference to an assembly that isn't in the GAC?

• How do I get a reference to the current project in an Eclipse plugin?

  - by Martin Doms

  I'm creating an editor for Eclipse. Right now the editor fires up with the user creates a new file with the appropriate extension. My question is, how can I get a reference to the project in which the file resides? For example, say I have a workspace with 2 projects, P1 and P2. I right click P2 and create a new file, can I get a reference to P2 from this somehow? Ultimately I need to reference the AST or Java Model of the project but even a String identifying the project would work.

• M2Crypto: Is PKey a reference to a Public or a Private key?

  - by Andrea Zilio

  In the PKey class documentation of the M2Crypto python package (an OpenSSL wrapper for Python) it is said that PKey is a reference to a Public key. My opinion is instead that it's a reference to a Private Key because the init method of the PKey class calls the evp_pkey_new openssl function that, from this link: http://linux.die.net/man/3/evp_pkey_new , should allocate a new reference to a private key structure! There are two only possible explaination: The M2Crypto documentation is wrong or the link I've reported has wrong informations. Can someone help me to find the truth?

• Putting a simple if-then statement on one line

  - by Abizern

  I'm just getting into Python and I really like the terseness of the syntax. However; is there an easier way of writing an if-then statement so it fits on one line? For example; say I have the simple test: if count == N: count = 0 else: count = N + 1 is there a simpler way of writing this? I mean, in Objective-C I would write this as: count = count == N ? count = 0 : count = N + 1; Is there something similar for python? Edit I know that in this instance I can use count == count % N. I'm asking about the general syntax.

• Mysql: how to generate count table by PATTERN / LIKE statement ? very tricky

  - by Abdulrahman Al-Qabandi

  to simplify, I got a database of registered users, I want to count how many emails there are for each email domain name (note I do not know all domain names) for example, Users table- id | email ------------------ 1 | [email protected] 2 | [email protected]<--unknown to me 3 | [email protected]<--unknown to me 4 | [email protected] 5 | [email protected]<--unknown to me 6 | [email protected] 7 | [email protected] 8 | [email protected] ( note: I want to count each email without specifying which email exactly ) so the result I want is suffix | count hotmail.com | 3 somesite.aaa | 2 unknownsite.aaa| 1 yahoo.com | 2 again, I stress this, I do not know unknownsite.aaa nor can i mention it in a statement because it is unknown to me, i hope I am clear. So essentially I want to make a statistic of what my website users use as an email host website. but like I said and I will repeat the third time, I do not know every mailhost that exists. I am going to investigate this more, I have a feeling this is something mysql cannot handle.

• Can I lock rows in a cursor if the cursor only returns a single count(*) row?

  - by RenderIn

  I would like to restrict users from inserting more than 3 records with color = 'Red' in my FOO table. My intentions are to A) retrieve the current count so that I can determine whether another record is allowed and B) prevent any other processes from inserting any Red records while this one is in process, hence the for update of. I'd like to do something like: cursor cur_cnt is select count(*) cnt from foo where foo.color = 'Red' for update of foo.id; Will this satisfy both my requirements or will it not lock only the rows in the count(*) who had foo.color = 'Red'?

  I am preparing a chart which will display the number of orders placed for a particular day in the current month and year. I wanted the count of orders placed for each day. I am showing the count of orders on the y-axis and the day on the x-axis. In my database, there is table called "order" in which order data is placed: order date, user_id, order_price, etc. For example, if on 4 July, 10 orders are placed, on 5 july, 20 orders are placed, and so on. How can I get the count of orders placed for day of the current month?

• Visual Studio adds a circular reference when I drag and drop a user control from the Toolbox

  - by JoelFan

  I have a user control C that is defined inside project P. C is present as a ".NET Framework Component" in my Visual Studio Toolbox. I open a form F (also defined inside project P) and drop C onto F. Once I do that drop, Visual Studio adds a reference under P pointing to P's own DLL. This is unnecessary and causes tons of build errors like The call is ambiguous between the following methods or properties... after which it lists the exact same method twice. If I go into References and delete the added reference, it builds correctly. Can I prevent VS from adding this unnecessary reference?
