    - Second audio file gets truncated I am using Windows Media Player to play my half second audio files one after the other using the code below... My problem comes when I play a second audio file immediately after the first one stops sometimes on slower computers the audio on the second file gets truncated on the beginning of playing the second file. What can I do to minimize this truncation of audio? Right now I am having to add 1 second of blank audio to the beginning of the second audio file but I would rather not have the delay. Here the code I am using ... +++++++++++++++++++++++ ' Play first voice file AxWindowsMediaPlayer1.URL = voice1.mp3 ' Play echo voice file once first one completes If e.newState = Me.AxWindowsMediaPlayer1.playState.wmppsStopped then BeginInvoke(New MethodInvoker(AddressOf playItAgain)) end if Private Sub playItAgain() AxWindowsMediaPlayer1.URL = voiceEcho.mp3 End Sub +++++++++++++++++++++++ Thanks!

    - RegEx: Groups Hello, I want to process an SQL string. It should leave only the SELECT-part, the rest should be cut. SELECT bla, bli from hallo WHERE x=4 I define three groups with  and substitute it only by the first group. In my editor vim the subsitution works as follows: :s/^$.*$$[ ^I]\+from[ ^I]\+$$.*$$/\1 results in SELECT bla, bli Question: Beside of the reg-ex-dialect ( i.e. .Net uses () instead of  ), how do I work with Groups in .Net?

    - Moving to a new development computer Hi, I am using Visual Studio 2003. After moving my project to a new development computer my project compiles and works on the new development computer but the program will not work when I test it on the client's computer. . I checked and both old and new development computers have the same list of references. When I switch out only the exe that was compiled using the same project code on the old dev computer the client installation likes that exe. What am I missing on getting the new development computer configured to compile like the old one? Thanks! Bob Tag: Communicating between services Tag: 415278

    - DataTable NewRecord, Delete, then AcceptChanges Assuming that I have a table with a single, auto-generated primary key and a TableAdapter/DataTable that references it, what would happen if I add a new row to the DataTable in code, Delete it, then pass it to the TableAdapter's Update method? Would calling AcceptChanges have an effect on this? I'm building a wizard that allows the user to enter information into a gridview. the gridview's rows and columns are dynamically generated based on selections on the wizard's first page. i commit the gridview's data in bulk when the wizard's finish button is clicked. i'm concerned that the back and forth movement between page one and two will generate a complex series of NewRows, Deletes, etc. that will make saving the data a huge challenge. thoughts appreciated. thanks in advance.

    - Configuration Manager - missing / cannot find. I am going throug a vb 2005 book, but I am using vs 2008 professional, and I cant seem to find a menu option its talking about. I am wondering if this has moved - i cannot seem to find it for the life of me in any of the menus. Looking at the help file however - it says the menu option is exactly how my book states but I do not have it. I created a Dummy Windows Application - saved it ( solution and project ) and I cannot find the Configuration Manager. -----------here is what the windows help says under (Configuration Manager) You can create your own configurations using the Configuration Manager dialog box. To open the Configuration Manager dialog box In Solution Explorer, select the solution. On the Build menu, choose Configuration Manager. <I do not have this menu option > ------------here is what my book says It says - To create a custom project configuration, select the Configuration Manager command on the Build menu or on the context menu that appears when you right-click the solution node in the Solutions Explorer. ( See figure 4-15. ) Figure 4-15 has a window "Configuration Manager the top dropdown box has a label of "Active Solution Configuration" with a "Debug" option selected... and beside it there is an "Active Solution Platform:" label with a dropdown with "Any CPU" listed There is a datagride with a heading label: "Project contexts (check the project configurations to build or deploy): and the columns are: Project / Configuration/ Platform / Build I have noticed that there is a difference in the toolbar above that has an icon "Start Debugging", I do not have a dropdown that shows the "Debug or Release or Configuration Manager" dropdown box.

    - Extra Property on Controls -- IExtenderProvider vs Inherited Class Hello, I'm migrating a VB6 app to .Net and of course it uses the DataField property for databinding, which of course isn't available under .Net. On several forms it also uses the Tag property to "group" controls for display/enabling, so I can't just switch from DataField to Tag. Which would you consider the better practice -- to create a subclass of the various controls and and the extra property that way, or to use an IExtenderProvider class to add it? (Of course the 3rd option is to simply use a naming convention to "hold" the extra information, but I don't like that). Any suggestions? Comments? -- J.B.

    - asp.textbox with variable height In an asp.tablecell I have a textbox. The row has two cells. Sometimes the textbox is the tallest and sometimes the other cell is the tallest. When the other cell is that tallest I like to change the textbox's height to use the entire cell's height. That is I'd like the text box to just fit the cell's height but have a minimum height. Do you know how to do that? I'd guess it needs code behind but am not sure. Thanks Tag: Communicating between services Tag: 415248

It does not show in the Project References tab under References: or Unused References. It does not show up under Publish. Applications Files. It is listed in Publish.Prerequisites, but is unchecked.

    - Setting Single Cell in DataGridView My apologies upfront for what I am sure is a newbie question, but I have been unable to find an answer via search. I am a VB6 programmer trying to write programs in VB 2008 Express. I have an 'unbound' datagrid control view on a form and just want to be able to write text to individual cells. I can programatically set the number of rows and cells, but have been unable to select and/or write to cells. Simple things that worked for the FlexGrid view in VB6 don't seem to apply; I can't just write (on a command button click event) me.datgridview1.row= 1 ; me.datgridview1.col= 1 ; me.datgridview1.text= "something" These all seem to result in syntax errors. How do I do a simple thing like this? Thanks in advance Tag: Communicating between services Tag: 415218

    - Save Files from my desktop to SQL Server We have a ASP.Net/SQL Server application that is used as a document management system. The documents are stored per project. The files are stored on a file server but we store the file name in the database and when displaying the files build a grid at run time to allow users to view the files like http://servername/files/filename.doc The problem we have currently is users have to use the web form to upload the files to database. Most users will work in thier local pc and when done will use the form to upload the file. What we want them to be able to do is to Right Click on any document/file and select "Save to Doc Manager" function. They enter the project id and the file is then saved automatically using the same method that is used on the web. i.e. copy the file to a specific location and add an entry to the sql server table. Does anyone know how this can be achieved? Thanks Jas Tag: Communicating between services Tag: 415215

    - UTCNow <> GMT Hi there I'm trying to use the IsDaylightSavingTime property of the datetime object. The PC I am using is in GMT, DateTime.Now.IsDaylightSavingTime() returns true DateTime.UtcNow.IsDaylightSavingTime() returns false The times also differ by 1 hour. As far as I was aware, GMT = UTC http://www.dxing.com/utcgmt.htm But quite evidently .NET thinks otherwise. I desperately need a resolution to this. Any idea how I get the time in GMT with VB.NET?

    - VS2005 vb.net DLL - interop EXCEL Hello All I am working a on web application created in Visual Studio 2005 VB. It has to do some work with Excel files, so I created a DLL in VS2005. My development machine is XP SP3. When my web app runs it opens a few excel files and fills certain locations and then the excel spreadsheet is calculated. (there are many calculations) To ensure I was closing only the files I had opened during this process I use code like this: Dim ClassName As String = "XLMain" Dim XLNumbers As Int16 Dim WindowHandle As Int32 Dim ReturnVal As Int32 Const WM_QUIT = &H12 For XLNumbers = 12 To 17 WindowHandle = FindWindow(ClassName, "Microsoft Excel - ROI_" & Request.QueryString("ROIHeaderID") & "_" & CStr(XLNumbers) & ".xls") If WindowHandle Then ReturnVal = PostMessage(WindowHandle, WM_QUIT, 0, 0) End If Next WindowHandle = FindWindow(ClassName, "Microsoft Excel - ROI_" & Request.QueryString("ROIHeaderID") & "_ALL.xls") If WindowHandle Then ReturnVal = PostMessage(WindowHandle, WM_QUIT, 0, 0) End If This works perfectly on my development machine. The deployment machine is Windows Server 2003. None of the excel files close using the code above. The only thing that works there is using something like this: ' check for any EXCEL processes that stuck Dim objWMIcimv2 = GetObject("winmgmts:" _ & "{impersonationLevel=impersonate}!\\.\root\cimv2") 'Connect to CIMV2 Namespace Dim objList = objWMIcimv2.ExecQuery _ ("select * from win32_process where name='EXCEL.EXE'") 'Find the process to terminate Dim objProcess As Object Dim intRslt As Int16 For Each objProcess In objList intRslt = objProcess.Terminate 'Terminates a process and all of its threads. Next Now while this removes the excel files in memory, it removes ALL of them. As this is meant to work with a web site and more then 1 (but maybe 5 total concurrent users) person may be using the site, this isn't a viable solution. The files are opened like this: (there is a reference to excel in the DLL project) Dim xlAppl As Excel.Application Dim xlSheet As Excel.Worksheet xlAppl = New Excel.Application xlAppl.Workbooks.Open(strFileName) xlAppl.Workbooks(1).Activate() strSheetName = "Input Sheet" xlSheet = xlAppl.Sheets(strSheetName) *** code fills in some values xlAppl.Workbooks(1).Save() xlAppl.Quit() xlAppl = Nothing Some files are left open using this code, which lead me to find something that allows me to clean up after this. Is it possible to target process that have certain file names open and shut them down, in windows server 2003? Maybe it would just be better for the web app to fill a queue of excel files that need processing .. and have a desktop application running under a username? (though they really require feed back of the changes the new calculations made .. which are saved to a database) Any ideas about getting excel to actually close when its asked to? Thanks Tag: Communicating between services Tag: 415174

This file can not be registered.=94 I believe that I need to include some code in my class in order for it to register.

    - Issues w/ using a DataTable with a TableAdapter's Update method I created a TableAdapter (TA) in my VB 2005 project. I tested it to ensure that its CRUD functionality is what I expected it to be. I'm using the TA and its strongly-typed DataTable (DT) in my Wizard. Initially, I populate the DT using the TA.GetData. I pass the DT to a ASCX-styled control that 'pivots' (turns years into columns) the data into a new DataTable (DT2), then binds it (DT2) to a GridView form. I save the original DT in the viewstate. So far so good. When I want to save the data, I compare the values in GridView to the DT that has been retrieve from the viewstate. The DT's rows are modified accordingly. So far so good. However, when I attempt to use the TA's Update method, passing the DT, I get an error about a missing parameter. I'm assuming that the parameter's value is supplied by the field that has a matching name. I've noticed that each row has a value in this field. What am I missing here? Another oddity, perhaps. If don't make an changes in the pivot grid, there won't be any changes to the DT. Why is it that the each row's rowstate is 'modified'? Could this be related my the Update issue? Thanks in advance.

    - Architecture question When filling class data from a relational database, what are some good ways to minimize the data load to only the data you need? I will provide the following example to illustrate (simplified): Class Ingredient Public Property Ingredents As List(Of Ingredient) Class Recipe Public Property RecipeName as String Public Property Ingredients As List(Of Ingredient) Class MenuItem Public Property MenuItemName as String Public Property MenuRecipe As Recipe In one form, I might be trying to look at a list of all the recipes in our database so I would only pull the RecipeName out of the database since recursively gathering the ingredient list would slow it down quite a bit. In another form I may need to gather all the recipes and their main ingredients (without the recursive call to get the Ingredient.Ingredients() ), at other times I want all of the information. How can I design my classes, or data classes in such a way that I achieve this outcome without adding a ton of overloaded methods and calls to my database? One of my thoughts was to place the database call in the property of the classes as such: Private _ingredientList as List(Of Ingredient) Public Property IngredientList As List(Of Ingredient) Get If _ingredientList Is Nothing _ingredientList = GetIngredientsFromDatabase() End If Return _ingredientList End Get .... The problem I have so far with this method is that it makes multithread applications a little more complex than they need to be, and it forces many calls to the database over and over again. A better method for loading all the recipes and their ingredients would be to collect all of the recipes and ingredients from the database, then loop through the data and "fill" the classes, that would reduce the database calls from a potential of hundreds down to 2, certainly preferable. A mix of the two options seems to be a way to go, but I wanted to prod the minds of the good folks on the usenet for ideas (as a solo developer, i can only bounce ideas off the wall, which is fun, but gets me nowhere most of the time) Thanks in advance, Charlie Tag: Communicating between services Tag: 415114

    - Program Startup During my program startup I need to check for a couple of things. 1. I need to check for network availability 2. I need to check for database connectivity 3. I need to check for access to the server via a webservice I have written the code to do all of these things. Now I want to put them into a startup form. I want to load my main form, but from the main form I want to call a splash screen with an animation on it that will cycle through all the above events. This will let the user know there is action going on. Also, if the network or database connection fails, I want to prevent them from using the program or store the files locally. If the server cannot be accessed, I will write the data to the database then process later. Again the code for these actions are done. What I need is a really good way of showing a splash screen, update a label on the splash screen while checking for these items, then close the splash screen. I can load the splash screen as follows Dim mySplash as new splashScreen mySplash.Show This will show the screen, but I need suggestions to update the label on the screen while checking for the items above. Anyone have a good idea or can point me to an article on a good way to use a splash screen? Thanks. John Tag: Communicating between services Tag: 415107

    - Reducing Quicktime resources in VB.NET app Hi all: I understand this is a rather vague question at this point, I'm not sure how to narrow it down at the moment.... I'm developing an app where I am launching multiple QT windows (using the QT component). In watching the system resources, as one might expect, each instatiation uses more and more memory. It looks like it's fairly easy use up 300-400MB with the launch of 6-8 windows. A few questions. 1. If I 400MB memory resources is the upper end I'll use (by limiting the number of windows instatiated) would that be considered too much for a 1-2 y.o computer with 1GB of RAM? 2. Anyone have any ideas on how I might launch a QT video, have it play and still release some memory. TIA for any help. Norm Tag: Communicating between services Tag: 415104

    - KeyUp event captures msgbox response I'm writing a data entry application where many fields are validated and committed through KeyUp capturing a Return keycode. My problem is that if a message box pops up and the user presses the Enter key to respond, that keystroke is captured by the form KeyUp event. An example is the user changing a field value and a message box displays warning that account codes must be changed if the entered value is committed. The user presses the Return key to respond OK and the form previews the keystroke and commits the change. Do I need to use the form AcceptButton property and change that for each field? -- DMNichols Tag: Communicating between services Tag: 415098

    - Manually painting a ToolStripSplitButton Hi all, I'm handling all the painting for a ToolStrip in my app due to some specialised requirements. Most of it has been relatively easy with a bit of trial error, but I've hit a stumbling block when trying to draw a ToolStripSplitButton. I'm overriding the OnRenderSplitButtonBackground sub, and I *do* call MyBase.OnRenderSplitButtonBackground(e), but I'm not getting the dropdown chevron at all. My ToolStripDropDownButtons paint the chevron themselves with no fuss, and I'd really like to maintain consistency by keeping all the dropdown chevrons identical. I understand if I have to manually add the chevron myself, but is there a predefined method for doing this? I checked through all of the ControlPaint class and the SystemIcons class, but neither one appears to contain the chevron for a ToolStripSplitButton's dropdown.

You need to research Inter Process Communication (IPC).

IPC can be achieved by using remoting with an IPC channel (or even TCP
channel if you wanted them to communicate across machine boundaries).

I believe .NET 2.0 and above also included IO methods for named pipes, which
is another way.

I'm sure WCF has classes to replace all of the above also, but I've not
investigated it.

Plenty out there to work with anyway :-)

I'm guessing you're talking about Windows services and not Web
Services, but I'll respond just in case. For a web service to
communicate with another web service it takes nothing more than adding
a reference to the other web service from the right+click menu on the
solution explorer.
