  • Error: A SQLParamenter wtih ParameterName @myparm is not contained by this SQLParameter Collection

    - by SidC
    Good Morning, I'm working on an ASP.NET 3.5 webforms application and have written the following code: Protected Sub btnSubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSubmit.Click Dim connectionString As String = WebConfigurationManager.ConnectionStrings("Diel_inventoryConnectionString").ConnectionString Dim con As New SqlConnection(connectionString) Dim adapter1 As New SqlDataAdapter adapter1.SelectCommand = New SqlCommand adapter1.SelectCommand.CommandType = CommandType.StoredProcedure adapter1.SelectCommand.CommandText = "PartSproc" Dim parmNSN As New SqlParameter("@NSN", SqlDbType.NVarChar) Dim parmName As New SqlParameter("@PartName", SqlDbType.NVarChar) txtNSN.Text = adapter1.SelectCommand.Parameters("@NSN").Value txtSearch.Text = adapter1.SelectCommand.Parameters("@PartName").Value Dim dt As New DataTable() adapter1.Fill(dt) MySearch.DataSource = dt MySearch.DataBind() End Sub When I run the page, I receive the error A SQLParameter with @NSN is not contained by this SQLParameter Collection. I tried using apostrophes around the @NSN and @PartName but that does not work either and presents expression expected error. How might I rectify the above code so that it references the @NSN and @PartName parameters correctly? Thanks, Sid

  • gdb: SIGTRAP on std::string::c_str() call

    - by sheepsimulator
    So I've been trying to use gdb to return the value of a string I have by calling > print <member variable name>.c_str() But everytime I do so, I get this: Program received signal SIGTRAP, Trace/breakpoint trap. <some address> in std::string::c_str() from /usr/lib/libstdc++.so.6 GDB remains in the frame where the signal was received. To change this behavior use "set unwindonsignal on" Evaluation of the expression containing the function (std::string::c_str() const) will be abandoned. Two questions: Why/how is the standard library throwing SIGTRAP? I checked basic_string.h and c_str() is defined as: const _CharT* c_str() const { return _M_data(); } I don't see any SIGTRAP-throwing here... is there a way to get around this SIGTRAP? How can I read the text value of the std::string out (without getting some crazy extension library) in gdb?

  • Delphi component or library to display mathematical expressions

    - by Svein Bringsli
    I'm looking for a simple component that displays mathematical expressions in Delphi. When I started out I thought it would be easy to find something on the net, but it turns out it was harder than anticipated. There are lots and lots of components that will parse mathematical expressions, but few (none?) that will display them. Ideally I would like a component as simple as a TLabel, where I could set the caption to some expression and it would be displayed correctly, but some sort of library that let's me draw expressions to a canvas would also be sufficient for my needs. Update: I'm not talking about plotting graphs of functions or something like that. I want to display (for instance) (X^2+3)/X like this:

  • Javascript substrings multiline replace by RegExp

    - by Radek Šimko
    Hi, I'm having some troubles with matching a regular expression in multi-line string. <script> var str="Welcome to Google!\n"; str = str + "We are proud to announce that Microsoft has \n"; str = str + "one of the worst Web Developers sites in the world."; document.write(str.replace(/.*(microsoft).*/gmi, "$1")); </script> http://jsbin.com/osoli3/3/edit As you may see on the link above, the output of the code looks like this: Welcome to Google! Microsoft one of the worst Web Developers sites in the world. Which means, that the replace() method goes line by line and if there's no match in that line, it returns just the whole line... Even if it has the "m" (multiline) modifier...

  • Tentative date casting in tsql

    - by Tewr
    I am looking for something like TRYCAST in TSQL or an equivalent method / hack. In my case I am extracting some date data from an xml column. The following query throws "Arithmetic overflow error converting expression to data type datetime." if the piece of data found in the xml cannot be converted to datetime (in this specific case, the date is "0001-01-01" in some cases). Is there a way to detect this exception before it occurs? select [CustomerInfo].value('(//*:InceptionDate/text())[1]', 'datetime') FROM Customers An example of what I am trying to achieve in pseudocode with an imagined tsql function TRYCAST(expr, totype, defaultvalue): select TRYCAST( [CustomerInfo].value('(//*:InceptionDate/text())[1]', 'nvarchar(100)'), datetime, null) FROM Customers

    I want to get multiple file by parsing a input file Through Java. The Input file contains many fasta format of thousands of protein sequence and I want to generate raw format(i.e., without any comma semicolon and without any extra symbol like "", "[", "]" etc) of each protein sequence.

  • Catch $.getJSON error

    - by Switz
    I've been trying to figure this out for hours. I have a DYNAMIC youtube search, which I use Youtube's JSON api for. It works usually, but there are times that it won't find anything. Is there a way to figure out if it finds nothing, and then end the function because otherwise it stops the entire code. I tried jsonp, but that didn't seem to be correct. Somewhere I read that error catching is built into the newest jQuery getJSON, but I couldn't find it. The code is really tedious so I'd rather not post it unless it comes to that. I'd appreciate any help! Thanks guys. error showing that json didn't return anything jquery-1.4.4.min.js:32 TypeError: Result of expression 'j' [undefined] is not an object.

  • Is it possible to use DLR in a .NET 3.5 website project?

    - by Aplato
    I'm trying to evaluate an expression stored in a database i.e. "if (Q1 ==2) {result = 3.1;} elseif (Q1 ==3){result=4.1;} else result = 5.9;" Rather than parsing it myself I'm trying to use the DLR. I'm using version .92 from the Codeplex repository and my solution is a .NET 3.5 website; and I'm having conflicts between the System.Core and Microsoft.Scripting.ExtenstionAttribute .dll's. Error = { Description: "'ExtensionAttribute' is ambiguous in the namespace 'System.Runtime.CompilerServices'.", File: "InternalXmlHelper.vb" } At this time I cannot upgrade to .NET 4.0 and make significant use of the .net 3.5 features (so downgrading is not an option). Any help greatly appreciated.

  • Capturing the contents of <select>

    - by joey mueller
    I'm trying to use a regular expression to capture the contents of all option values inside an HTML select element For example, in: <select name="test"> <option value="blah">one</option> <option value="mehh">two</option> <option value="rawr">three</option> </select> I'd like to capture one two and three into an array. My current code is var pages = responseDetails.responseText.match(/<select name="page" .+?>(?:\s*<option .+?>([^<]+)<\/option>)+\s*<\/select>/); for (var c = 0; c<pages.length; c++) { alert(pages[c]); } But it only captures the last value, in this case, "three". How can I modify this to capture all of them? Thanks!

  • Why won't this SQL CAST work?

    - by Kev
    I have a nvarchar(50) column in a SQL Server 2000 table defined as follows: TaskID nvarchar(50) NULL I need to fill this column with some random SQL Unique Identifiers (I am unable to change the column type to uniqueidentifier). I tried this: UPDATE TaskData SET TaskID = CAST(NEWID() AS nvarchar) but I got the following error: Msg 8115, Level 16, State 2, Line 1 Arithmetic overflow error converting expression to data type nvarchar. I also tried: UPDATE TaskData SET TaskID = CAST(NEWID() AS nvarchar(50)) but then got this error: Msg 8152, Level 16, State 6, Line 1 String or binary data would be truncated. I don't understand why this doesn't work but this does: DECLARE @TaskID nvarchar(50) SET @TaskID = CAST(NEW() AS nvarchar(50)) I also tried CONVERT(nvarchar, NEWID()) and CONVERT(nvarchar(50), NEWID()) but got the same errors.

  • JavaScript lazy regex for matching HTML tags

    - by Grnbeagle
    Hi, I'm having a problem writing a regular expression for matching HTML tags. I found a similar entry here, but this didn't quite work in my case. Here's my test string: <div id="div0" class="myclass">here's some text that may include whitespace</div><div id="div1" class="myclass"> and some more here </div> And here's my regex based on the aforementioned entry: <div[^>]*class="myclass">[^~]*?<\/div> Note that I need to match the first instance of <div /> with class of "myclass." The content may have carriage returns. These <div> tags won't be nested. Here's a rubular page for testing: http://rubular.com/r/vlfcikKMXk

  • How to Redirect Subdomains to Other Domain

    - by Codex73
    What I'm trying to accomplish with htaccess mod-rewrite: Redirect all sub-domains to new domain name w rewrite rule. e.g. test1.olddomain.com === test1.newdomain.com test2.olddomain.com === test2.newdomain.com test3.olddomain.com === test3.newdomain.com This is what I have so far which of course is wrong: Options +FollowSymLinks RewriteEngine on RewriteCond %{HTTP_HOST} ^olddomain\.com$ [NC] RewriteRule ^(.*)$ http://www.newdomain.com/$1 [R=301,L] RewriteCond %{HTTP_HOST} ^www\.olddomain\.com$ [NC] RewriteRule ^(.*) http://www.newdomain.com/$1 [R=301,L] RewriteRule [a-zA-Z]+\.olddomain.com$ http://$1.newdomain.com/ [R=301,L] Since I'm not a Regular Expression junkie just yet, I need your help... Thanks for any help you can give here. I know also we can compile these first two conditions into one. Note: The reason I don't redirect all domain using DNS is that a lot of directories need special rewrite rules in order to maintain positions on SEO.

  • LINQ query needs either ascending or descending in the same query

    - by Sir Psycho
    Is there anyway this code can be refactored? The only difference is the order by part. Idealy I'd like to use a delegate/lamda expression so the code is reusable but I don't know how to conditionally add and remove the query operators OrderBy and OrderByDescending var linq = new NorthwindDataContext(); var query1 = linq.Customers .Where(c => c.ContactName.StartsWith("a")) .SelectMany(cus=>cus.Orders) .OrderBy(ord => ord.OrderDate) .Select(ord => ord.CustomerID); var query2 = linq.Customers .Where(c => c.ContactName.StartsWith("a")) .SelectMany(cus => cus.Orders) .OrderByDescending(ord => ord.OrderDate) .Select(ord => ord.CustomerID);

  • Are there any other Java schedulers besides Quartz(FOSS) and Flux(Commercial)

    - by mP
    I am interested in finding out about other job scheduling packages besides Quartz and Flux. Given the plethora of web frameworks i find it perculiar that there is really only one scheduler. Are there others that perhaps are very much unknown/unpopular ? Spring Batch Not really a scheduling solution but rather a batch job coordinator etc. http://static.springsource.org/spring-batch/faq.html#schedulers How does Spring Batch differ from Quartz? Is there a place for them both in a solution? Spring Batch and Quartz have different goals. Spring Batch provides functionality for processing large volumes of data and Quartz provides functionality for scheduling tasks. So Quartz could complement Spring Batch, but are not excluding technologies. A common combination would be to use Quartz as a trigger for a Spring Batch job using a Cron expression and the Spring Core convenience SchedulerFactoryBean .

  • Why do Pascal control structures appear to be inconsistent?

    - by 70Mike
    Most Pascal control structures make sense to me, like: for ... do {statement}; if (condition) then {statement}; while (condition) do {statement}; where the {statement} is either a single statement, or a begin ... end block. I have a problem with: repeat {statement-list} until (expression); try {statement-list} except {statement-list} end; Wouldn't it be better that repeat and try have the same general structure, accepting only a single statement or a begin ... end block, instead of having a statement-list that's not formally blocked with a begin and an end?

  • Replace underscore between words (reg.exp)

    - by lasseespeholt
    Hey, I need a regular expression to solve the following problem (links to similar problems is also appreciated, related tutorials etc.): __some_words_a_b___ => __some words a b___ ____ => ____ So I want underscores between words to be replaced with space and keep leading and trailing underscores. I found this: ^[ \t]+|[ \t]+$ and I guess it most be something like that. I will use it in jQuery, Java (stdlibs) and maybe XSLT. Addition: The sentences do not necessarily start with underscores or ends with underscores. It is also possible that a sentence ain't containing underscores at all. Best regards Lasse Espeholt

  • Double pointer const-correctness warnings in C

    - by Michael Koval
    You can obviously cast a pointer to non-const data to a a pointer of the same type to const data: int *x = NULL; int const *y = x; Adding additional const qualifiers to match the additional indirection should logically work the same way: int * *x = NULL; int *const *y = x; /* okay */ int const *const *z = y; /* warning */ Compiling this with GCC or Clang with the -Wall flag, however, results in the following warning: test.c:4:23: warning: initializing 'int const *const *' with an expression of type 'int *const *' discards qualifiers in nested pointer types int const *const *z = y; /* warning */ ^ ~ Why does adding an additional const qualifier "discard qualifiers in nested pointer types"?

  • Making the shadow from a ScatterViewItem a different shape

    I am developing a program for Surface using Expression Blend and Visual Studio. I have a custom user control with an ellipse and a label in a grid. This will need to be placed in a scatterViewItem. My problem is that the scatterviewitem will cast a rectangle shaped shadow under the ellipse shaped content. I can disable the shadow completely, but is there any way to make the shadow inherit the shape from its parent? Or can i set the shape of the scatterviewItem itself in any way?

  • What's the point of lambda in scheme?

    - by incrediman
    I am learning scheme. I know how to use both lambda and let expressions. However I'm struggling to figure out what the point is of using lambda. Can't you do everything with let that you can with lambda? It would be especially helpful to see an example of a situation where a lambda expression is a better choice than let. One other thing - are there also situations where let is more useful than lambda? If so such an example would be nice as well. Thanks!

  • SQL Server T-SQL statement to replace/delete sub-strings

    - by StefanE
    Hi, I have a table with 6 columns containing HTML content with some markups in it and now when moving to a new designed site most of this HTML code has to be deleted. More or less all tags except <B> and </B>. Is there a nice way of doing this, identify all tags end delete them within the data? I'm sure there are no < symbols in the test so a regular expression would maybe work? My alternative is to fetch every row, process it and update the database but I'm guessing this is possible to do in T-SQL directly. My server is an MSSQL 2008 and is located in a hosted environment but I can fetch a local copy if needed. Thanks, Stefan

  • Synclock a section of code while waiting for ShowDialog to return

    - by clawson
    I'm having trouble working out how to lock my application out of a section of code while it waits for a response from an external program. I've used Synclock on a section of code with the Me object in the expression. In this Synclock I call an overridden ShowDialog method of a dialog box, which has a timeout parameter, but does return the value from the underlying ShowDialog function call ,once the timer is setup. Works like this. SyncLock Me Dim frmDlgWithTimeout As New frmDlgWithTimeout ' dialog box with overridden ShowDialog ' Dim res As DialogResult = frmDlgWithTimeout.ShowDialog(10 * 1000) ' 10 sec timeout ' End SyncLock Now, external programs may raise events that bring my application to this Synclock but it doesn't prevent it from entering it, even though the ShowDialog function hasn't returned a value (and hence what I thought would keep the section of code locked). There is only one instance of the object that is used for lock in the program. Your help is greatly appreciated.
