  • Reflection and changing a variables type at runtime?

    - by james-west
    Hi I'm trying to create an object Of a specific type. I've got the following code, but it fails because it can't cast the new table object to the one that is already defined. I need table to start of an IEnumerable type so I can't declare is an object. Public sub getTable(ByVal t as Type) Dim table As Table(Of Object) Dim tableType As Type = GetType(Table(Of )).MakeGenericType(t) table = FormatterServices.GetUninitializedObject(tableType) End sub So in short - is there a way of changing a variable type at runtime? (or a better way of doing what I'm doing) Thanks in advance. James

  • how to design a complex webreport in DevExpress XtraReport?

    - by ahmed
    Hello , I have to design a complex webreport with DevExpress Xtrareport .I have to pull data from 40 different tables on user selection and show on the Report. So I have designed in this way. On the design form I am giving the user to select the department section and project. with three dropdowns A) select the report , B) Sort by , C)Filter By A) Select the report contains different types like family status, insurance type etc ..total 40 types. B) Sort by will contain by employee number, date of birth , Salary , and many more C) Filter by will contain like employee on vacation, or employee terminated etc etc. Now for a single webreport I am first taking a DataSource and binding data to labels. to achieve the above webreport I have to take 40 different Datasource and I have to assign to the labels? Should I be doing this?

  • Does binarywriter.flush() also flush the underlying filestream object?

    - by jacob sebastian
    I have got a code snippet as follows: Dim fstream = new filestream(some file here) dim bwriter = new binarywriter(fstream) while not end of file read from source file bwriter.write() bwriter.flush() end while The question I have is the following. When I call bwriter.flush() does it also flush the fstream object? Or should I have to explicitly call fstream.flush() such as given in the following example: while not end of file read from source file bwriter.write() bwriter.flush() fstream.flush() end while A few people suggested that I need to call fstream.flush() explicitly to make sure that the data is written to the disk (or the device). However, my testing shows that the data is written to the disk as soon as I call flush() method on the bwriter object. Can some one confirm this?

  • Why does DataSet.HasChanges() return true if called in the same function as change but false otherwi

    - by Chapso
    Assuming that the buttons are being clicked in order, the following code modifies row 1 in a .net DataSet, then row 0. HasChanges returns true, but GetChanges only gives me the change for row 0. If I comment out the line in the button2 click event that modifies row 0, then HasChanges returns false. Can anyone explain to me why HasChanges() and GetChanges() only return true when they are called in the same function as the change to the DataSet? Protected Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click __ds1.Tables(0).Rows(1)("EmployeeName") = "TestStuff" End Sub Protected Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click __ds1.Tables(0).Rows(0)("EmployeeName") = "TestStuff" If __ds1.HasChanges(DataRowState.Modified Or DataRowState.Added) Then __ds2 = __ds1.GetChanges(DataRowState.Modified _ Or DataRowState.Added) GridView3.DataSource = __ds2.Tables("Users").DefaultView GridView3.DataBind() Else End If End Sub

  • Unable to get ncName and netBIOSName Properties

    - by Randz
    I've some code on the net regarding retrieval of NetBIOSName (Pre-windows 2000 domain name) of an Active Directory Domain. Here's my code sample: Me._rootDSE = New System.DirectoryServices.DirectoryEntry("GC://RootDSE", "", "") Dim results As System.DirectoryServices.SearchResultCollection = Nothing Dim ADSPath As String = "GC://CN=Partitions," + Me._rootDSE.Properties("configurationNamingContext").Value.ToString() Dim adse As System.DirectoryServices.DirectoryEntry = New System.DirectoryServices.DirectoryEntry(ADSPath, "", "") Dim searcher As System.DirectoryServices.DirectorySearcher searcher = New System.DirectoryServices.DirectorySearcher(adse) searcher.SearchScope = DirectoryServices.SearchScope.OneLevel searcher.Filter = "(&(objectClass=crossRef)(systemflags=3))" searcher.PropertiesToLoad.Add("netbiosname") searcher.PropertiesToLoad.Add("ncname") results = searcher.FindAll() If results.Count > 0 Then For Each sr As System.DirectoryServices.SearchResult In results Dim de As System.DirectoryServices.DirectoryEntry = sr.GetDirectoryEntry() 'netbiosname and ncname properties returns nothing System.Diagnostics.Trace.WriteLine(sr.GetDirectoryEntry().Properties("netbiosname").Value.ToString()) System.Diagnostics.Trace.WriteLine(sr.GetDirectoryEntry().Properties("ncname").Value.ToString()) Next End If When I am using the "(&(objectClass=crossRef)(systemFlags=3))" filter, I am not getting any result, but when I removed the systemFlags filter, I get some results. However, on the search results that I got, I still cannot access the values of ncName and NetBIOSName properties. I can get other properties like distinguishedName and CN of the search result properly. Any idea on what I might be doing wrong, or where to look further?

  • Animated Notify Icon like the task manager graph

    - by Blind Trevor
    Hi guys, I'm trying to create a bandwidth monitor - I've done most of it, but I want to have a notifyicon that changes dependent on the bandwidth. The same as when you open task manager and then minimise it, there is a little animated bar graph by the clock showing CPU usage... How do I do that??? Any help would be appreciated.

  • Visual Studio 2005 - OleDbConnection throws "Invalid authorization specification" in Form Designer,

    - by Jason Dagit
    I have a form with an OleDbConnection object on it. This form fails to load in the Form Designer with the message: One or more errors encountered while loading the designer. The errors are listed below. Some errors can be fixed by rebuilding your project, while others may require code changes. Invalid authorization specification at ADODB.ConnectionClass.Open(String ConnectionString, String UserID, String Password, Int32 Options) ... (stack trace continues into user code) I've tracked this down to the OleDbConnection string. If I hardcode in the server IP, username/password/dbinstance into the constructor of the GUI form then the form will load in the designer. At run-time it is not an issue because we require the user to provide the login details. The question: Is it possible to use the OleDbConnection and the Form designer without supplying the database credentials in the source code of the form? For example, is there a property of the OleDbConnection or Form that I can set so that it doesn't need to access the database during Form design? My concern is that if we ever move the database server or change the login that the code will stop working in the designer.

  • Designer serialization persistence problem in .NET, Windows Forms

    - by Jules
    ETA: I have a similar, smaller, problem here which, I suspect, is related to this problem. I have a class which has a readonly property that holds a collection of components (* not quite, see below). At design time, it's possible to select from the components on the design surface to add to the collection. (Think imagelist, but instead of selecting one, you can select as many as you want.) As a test, I inherit from button and attach my class to it as a property. The persistence problem occurs when I add a component,to the collection, from the design surface after I have added my button to the form. The best way to demonstrate this is to show you the designer generated code: Private Sub InitializeComponent() Dim Provider1 As WindowsApplication1.Provider = New WindowsApplication1.Provider Me.MyComponent2 = New WindowsApplication1.MyComponent Me.MyComponent1 = New WindowsApplication1.MyComponent Me.MyButton1 = New WindowsApplication1.MyButton Me.MyComponent3 = New WindowsApplication1.MyComponent Me.SuspendLayout() ' 'MyButton1 ' Me.MyButton1.ProviderCollection.Add(Me.MyButton1.InternalProvider) Me.MyButton1.ProviderCollection.Add(Me.MyComponent1.Provider) Me.MyButton1.ProviderCollection.Add(Me.MyComponent2.Provider) Me.MyButton1.ProviderCollection.Add(Provider1) //Wrong should be Me.MyComponent3.Provider ' 'Form1 ' Me.Controls.Add(Me.MyButton1) End Sub Friend WithEvents MyComponent1 As WindowsApplication1.MyComponent Friend WithEvents MyComponent2 As WindowsApplication1.MyComponent Friend WithEvents MyButton1 As WindowsApplication1.MyButton Friend WithEvents MyComponent3 As WindowsApplication1.MyComponent End Class As you can see from the code, the collection is not actually a collection of the components, but a collection of a property, 'Provider', from the components. It looks like the problem is occurring because MyComponent3 is created after MyButton. However, in my opinion, this should not make any difference - by the time the serializer comes to add the provider property of MyComponent3, it's already created. Note: You may wonder, why I'm not using AddRange to persist the collection. The reason for this is that if I do, the behaviour changes and none of the items will persist correctly. The designer will create local fields - like Provider1 - for each item in the collection. However if I add another collection to the class which holds the actual MyComponents and persist this, then, somehow, the AddRange method persists correctly in ProviderCollection! There seems to be some kind of quantum double slit experiment going down in code dom. How can I solve this problem?

  • A good way in .NET Winforms to have user entered time frame?

    - by Ben
    Hi, Does anyone know of a good way to have a user enter an amount of time (hours and minutes) using winforms controls? At the moment I have two numeric up downs, one for time and one for minutes that I then parse to create a timespan. The only other idea I have is a text box that a user can enter a "00:00" time in, and validate the input. Both of these ways seem a bit bad (in UI terms) though. Any ideas? Thanks

  • Class/Model Level Validation (as opposed to Property Level)? (ASP.NET MVC 2.0)

    - by Erx_VB.NExT.Coder
    Basically, what the title says. I have several properties that combine together to really make one logical answer, and i would like to run a server-side validation code (that i write) which take these multiple fields into account and hook up to only one validation output/error message that users see on the webpage. I looked at scott guthries method of extending an attribute and using it in yoru dataannotations declarations, but, as i can see, there is no way to declare a dataannotations-style attribute on multiple properties, and you can only place the declarations (such as [Email], [Range], [Required]) over one property :(. i have looked at the PropertiesMustMatchAttribute in the default mvc 2.0 project that appears when you start a new project, this example is as useful as using a pair of pins to check your motor oil - useless! i have tried this method, however, creating a class level attribute, and have no idea how to display the error from this in my aspx page. i have tried html.ValidationMessage("ClassNameWhereAttributeIsAdded") and a variety of other thing, and it has not worked. and i should mention, there is NOT ONE blog post on doing validation at this level - despite this being a common need in any project or business logic scenario! can anyone help me in having my message displayed in my aspx page, and also if possible a proper document or reference explaining validation at this level?

  • Export Multiple Crystal Reports ASP.NET

    - by AProgrammer
    Hey all, I want to export 2 different reports when I click an Export button. The problem is the routine only fires once and I only get one report to print out. Am I doing something wrong?

  • Dice face value recognition

    - by Jakob Gade
    I’m trying to build a simple application that will recognize the values of two 6-sided dice. I’m looking for some general pointers, or maybe even an open source project. The two dice will be black and white, with white and black pips respectively. Their distance to the camera will always be the same, but their position on the playing surface will be random. (not the best example, the surface will be a different color and the shadows will be gone) I have no prior experience with developing this kind of recognition software, but I would assume the trick is to first isolate the faces by searching for the square profile with a dominating white or black color (the rest of the image, i.e. the table/playing surface, will in distinctly different colors), and then isolate the pips for the count. Shadows will be eliminated by top down lighting. I’m hoping the described scenario is so simple (read: common) it may even be used as an “introductory exercise” for developers working on OCR technologies or similar computer vision challenges.

  • ShowDialog won't run

    - by clawson
    I've come across a situation where I try to run a simple line of code in a method Dim res As DialogResult = frmOptions.ShowDialog() but nothing happens. The dialog box will not appear. If I run this method from another location in the code it executes fine (i.e. displays the form in dialog mode and code executes fine thereafter). Hence, it may be the way in which I arrive at this code that is causing my problem, but I cannot see to find what is wrong. When I pause the debugger the line of code is highlighted in green but I can't see to step over it or into it. Any idea what may cause this to happen, or what I should be looking for that might be causing the problem?? Thanks for the help!

  • 2d terrain generation in real time

    - by Skoder
    Hey, I'm trying to create a game similar to this (Note:When you click 'play', there are SFX in the game which you can't seem to turn off, so you may want to check volume). In particular, I'm interested in knowing how the 'infinite' landscape is generated. Are there any tutorials/articles describing this? I came across procedural generation, but I'm not quite sure what topics I should be looking for (or if it's even procedural generation). (I'm using C#, but I don't mind the language as I assume the theory behind it remains the same) Thanks for any suggestions

  • .NET Regular Expression to split multiple words or phrases

    - by Cj Anderson
    I'm using the code below to take a string and split it up into an array. It will take: Disney Land and make it two separate elements. If the string contains "Disney Land" then it is one element in the array. Works great, however it adds some empty elements to the array each time. So I just iterate over the elements and remove them if they are empty. Is there a tweak to the code below that will prevent those empty elements from occurring? Private m_Reg As Regex m_Reg = New Regex("([^""^\s]+)\s*|""([^""]+)""\s*") Dim rezsplit = m_Reg.Split(criteria)

  • Regex For Finding Ctypes with Int32

    - by Stefan H
    (Hey all, I am looking for a little regex help... I am trying to find all CType(expression,Int32) s and replace them with CInt(expression) This, however, is proving quite difficult, considering there could be a nested Ctype(expression, Int32) within the regex match. Does anyone have any ideas for how to best go about doing this? Here is what I have now: Dim str As String = "CType((original.Width * CType((targetSize / CType(original.Height, Single)), Single)), Int32)" Dim exp As New Regex("CType\((.+), Int32\)") str = exp.Replace(str, "CInt($1)") But this will match the entire string and replace it. I was thinking of doing a recursive function to find the outer most match, and then work inwards, but that still presents a problem with things like CType(replaceChars(I), Int32)), Chr(CType(replacementChars(I), Int32) Any tips would be appreciated. Input returnString.Replace(Chr(CType(replaceChars(I), Int32)), Chr(CType(replacementChars(I), Int32))) Output: returnString.Replace(Chr(CInt(replaceChars(I))),Chr(CInt(replacementChars(I)))) Edit: Been working on it a little more and have a recursive function that I'm still working out the kinks in. Recursion + regex. it kinda hurts. Private Function FindReplaceCInts(ByVal strAs As String) As String System.Console.WriteLine(String.Format("Testing : {0}", strAs)) Dim exp As New Regex("CType\((.+), Int32\)") If exp.Match(strAs).Success Then For Each match As Match In exp.Matches(strAs) If exp.Match(match.Value.Substring(2)).Success Then Dim replaceT As String = match.Value.Substring(2) Dim Witht As String = FindReplaceCInts(match.Value.Substring(2)) System.Console.WriteLine(strAs.IndexOf(replaceT)) strAs.Replace(replaceT, Witht) End If Next strAs = exp.Replace(strAs, "CInt($1)") End If Return strAs End Function Cheers,
