    I am getting this exception while reading the shapes in excel sheet in c#: on code line of if (worksheet.Shapes.Count >= iCurrentRowIndex) {} Unable to cast COM object of type 'System.__ComObject' to interface type 'Microsoft.Office.Interop.Excel._Worksheet'.

  • How can I read individual lines of a CSV file into a string array, to then be selectively displayed

    - by Ryan
    I need your help, guys! :| I've got myself a CSV file with the following contents: 1,The Compact,1.8GHz,1024MB,160GB,440 2,The Medium,2.4GHz,1024MB,180GB,500 3,The Workhorse,2.4GHz,2048MB,220GB,650 It's a list of computer systems, basically, that the user can purchase. I need to read this file, line-by-line, into an array. Let's call this array csvline(). The first line of the text file would stored in csvline(0). Line two would be stored in csvline(1). And so on. (I've started with zero because that's where VB starts its arrays). A drop-down list would then enable the user to select 1, 2 or 3 (or however many lines/systems are stored in the file). Upon selecting a number - say, 1 - csvline(0) would be displayed inside a textbox (textbox1, let's say). If 2 was selected, csvline(1) would be displayed, and so on. It's not the formatting I need help with, though; that's the easy part. I just need someone to help teach me how to read a CSV file line-by-line, putting each line into a string array - csvlines(count) - then increment count by one so that the next line is read into another slot. So far, I've been able to paste the numbers of each system into an combobox: Using csvfileparser As New Microsoft.VisualBasic.FileIO.TextFieldParser _ ("F:\folder\programname\programname\bin\Debug\systems.csv") Dim csvalue As String() csvfileparser.TextFieldType = Microsoft.VisualBasic.FileIO.FieldType.Delimited csvfileparser.Delimiters = New String() {","} While Not csvfileparser.EndOfData csvalue = csvfileparser.ReadFields() combobox1.Items.Add(String.Format("{1}{0}", _ Environment.NewLine, _ csvalue(0))) End While End Using But this only selects individual values. I need to figure out how selecting one of these numbers in the combobox can trigger textbox1 to be appended with just that line (I can handle the formatting, using the string.format stuff). If I try to do this using csvalue = csvtranslator.ReadLine , I get the following error message: "Error 1 Value of type 'String' cannot be converted to '1-dimensional array of String'." If I then put it as an array, ie: csvalue() = csvtranslator.ReadLine , I then get a different error message: "Error 1 Number of indices is less than the number of dimensions of the indexed array." What's the knack, guys? I've spent hours trying to figure this out. Please go easy on me - and keep any responses ultra-simple for my newbie brain - I'm very new to all this programming malarkey and just starting out! :)

  • WPF ListView groups repeat column headers

    - by Riko
    Is there a way to repeat the column headers inside each group of a ListView.GridView when using a grouped CollectionViewSource as the source of the ListView? I am using the example at http://msdn.microsoft.com/en-us/library/ms754027.aspx which uses an Expander control to display each group. I would like the column headers to appear inside the expander for each group instead of at the top of the ListView.

  • How to use the callback method with a c++ directshow sample grabber

    - by Mr Bell
    I have a sample grabber hooked into my directshow graph, based on this example http://msdn.microsoft.com/en-us/library/dd407288(VS.85).aspx the problem is that it uses one shot and buffers. I want to continuously grab samples, and i'd rather have a callback than i guess polling for the samples. How do use the SetCallback method? SetCallback(ISampleGrabberCB *pCallback, long WhichMethodToCallback) how do I point pCallback to my own method?

  • Parallel programming patterns for C#?

    - by VoidDweller
    With Intel's launch of a Hexa-Core processor for the desktop, it looks like we can no longer wait for Microsoft to make many-core programming "easy". I just order a copy of Joe Duffy's book Concurrent Programming on Windows. This looks like a great place to start, though, I am hoping some of you who have been targeting multi/many core systems would point me to some good resources that have or would have helped on your projects?

  • Free CodeRush Express: worth the time?

    - by rp
    DevExpress has announced a free express version of CodeRush (for C# and VB.Net). http://blogs.microsoft.co.il/blogs/kim/archive/2008/10/28/coderush-for-free-coderush-xpress-for-visual-studio-announced.aspx I've read about CodeRush Pro and suspect that it is probably worth the money--but I've always had other things I needed to spend the money on. Is CodeRush Express worth the time and effort to download and learn to use. It's help file didn't install and I'm a little frustrated as to how to use it. Thanks, rp

  • DataTrigger only works on first TabItem in TabControl

    - by JustusJonas
    Hi! It seems like a bug in WPF, but maybe someone has an answers to this. I have a DataTrigger for an editable ComboBox. It works on the first TabItem of my TabControl, but not on the second. If you switch the first with the second TabItem, the "second" will work. The same effect happens when you give the style exactly to the ComboBox (ComboBox.Stye ...). <Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" x:Class="MainWindow" x:Name="Window" Title="MainWindow" Width="640" Height="480"> <Window.Resources> <Style TargetType="{x:Type ComboBox}"> <Setter Property="Height" Value="25" /> <Setter Property="Width" Value="125" /> <Style.Triggers> <DataTrigger Binding="{Binding ElementName=PART_EditableTextBox, Path=IsFocused}" Value="True"> <Setter Property="BitmapEffect"> <Setter.Value> <OuterGlowBitmapEffect GlowColor="Red" GlowSize="5" /> </Setter.Value> </Setter> </DataTrigger> </Style.Triggers> </Style> </Window.Resources> <Grid x:Name="LayoutRoot"> <TabControl> <TabItem Header="TabItem1"> <Grid> <ComboBox IsEditable="True"/> </Grid> </TabItem> <TabItem Header="TabItem2"> <Grid> <ComboBox IsEditable="True"/> </Grid> </TabItem> </TabControl> </Grid>

  • CodePage ID to CodePage name: GetEncoding equivalent in Delphi?

    - by Steve
    Hello all, I'm looking for a Win32 equivalent of the .Net Encoding.GetEncoding Method to be used in Delphi7. What I would like to achieve is to convert a Codepage ID (ie.: 28592) to a Codepage name (iso-8859-2 in this case). I've found a Win32 function called GetCPInfoEx, but that returns a long CodePage name, and I need the short one, like the ones listed on this page: (see Name column) http://msdn.microsoft.com/en-us/library/system.text.encoding.aspx Thank you!

  • Flash-based Document Viewer/Converter (FlashPaper alternative, but with automated converter support)

    - by Mauricio
    Hey stackoverflow community, I am looking for a Document Viewer application that I can embed in a Flash/Flex application that supports Microsoft Office documents as well as PDF. I have looked into print2flash as a possibility, but their automated converter executable requires access to the files and directories. Does anyone know of other alternatives which would have .NET/Java/Other libraries to convert these files to a SWF that can do it based on the download stream, as opposed to the actual files? Thanks!

    I think thaAjaxControlToolkitTextBoxWrapperThis use to work, but I think that upgrading to te latest version of teh Toolkit (4 something) broke it: var txtExpireYear = document.getElementById("ctl00_phPageContent_dtmPassportExpirationDate_txtYear"); txtExpireYear.AjaxControlToolkitTextBoxWrapper.set_Value(dtmDateOfExpire.getFullYear()); I now get the error: Microsoft JScript runtime error: 'AjaxControlToolkitTextBoxWrapper' is null or not an object Executing this: txtExpireYear.innerText="value1" txtExpireYear.value="value2" results in the watermark text being changed, not the textbox's text.
