• Visual Basic IDE says OK but compilation fails

  I am developing a web site/system using VS2005, ASP.NET and VB.NET. Suddenly I ran into a problem where I cannot build my site any more. The message is: ..path../UserOwner.aspx.vb(1278,0): error BC30451: Name 'a3333' is not declared. BUT the (in this case) label a3333 is declared. When I edit the behind code there is also no "bubble lines" telling me there is a problem. But as soon as I hit Run - I get this message in this code. It look's like I have hit a "limit" as all objects created "before" in this page works perfect, but all objects "after" fails in the compilation. This happens around the 180th object on this page. If I as example drop a new button object on the page - set's the ID ...Show All

• SQL Server How to define a Left Outer Join in report using ReportModel as DataSource

  Dear ppl, I got a Report Model Project, in which i have created a model of my Database and deployed it on the server... Then I have a Report Server project for my reports. The reports are using Report Model as the DataSource... Now in the Report Designer, inside a report, when I define query for Dataset using Report Model , I can't find a way to write a left Outer Join query... It always performs Inner Joins... was wondering ether Report model supports Outer Joins ... I might achive this using two different datasets but then i'll end up using two data regions e.g. 2 tables, but i don't want to do that... instead I want all of my data to appear in a single table which can reference to single dataset. Is there a way to define ...Show All

• SQL Server Which DB should I use for a PocketPC app?

  I'm planning a Pocket PC / Windows Mobile application, but I'm a bit confused on which mobile database I should start development with. I've read about SQL CE, SQL Everywhere, and SQL Mobile. Should I be using SQL Server CE 3.1 for my Pocket PC application The database will be preloaded with data at design time with read-only information, and will be a "private" installation for a single user application. My main concern is that the solution can be installed on PPC 2002, 2003 and Mobile 2005. Am I on the right track Thanks, Jordan SQL Server Everywhere Edition was renamed to be SQL Server Compact Edition, which to the best of my knowledge is the successor to SQL Server Mobile.

• Visual C++ Problem with char *

  How can I copy 2 char * in a third one, so it seems like this char *one = "This"; char *two = "is a text."; char *three = ... And it has to be native C++. It doesn't seem to work. I've tested it with the following code: char test1[80] = "first"; strcpy(test1, "test."); strcat(test1, " And with strcat"); printf("First text: %s \n", test1); system("pause"); char *test2 = "second"; strcpy(test2, "test"); strcat(test2, " And with strcat"); printf("Second text: %s \n", test2); system("pause"); And with the test1[80] it works, but with the char* it causes the program ...Show All

• SQL Server Connection manager validation within UI

  Hi all, I need to validate a custom connection manager within its custom user interface, like the FlatFileConnectionManager does it, by showing errors and warnings at the bottom of the window. How can I do that since SSIS provides only a ConnectionManager object with the IDtsConnectionManagerUI::Initialize method, and this object doesn't contain any Validate method Note that for a custom data flow component, SSIS provides a ComponentMetaData object which supports a Validate method. Thanks. Pascal I can't call the Validate method of my custom connection manager because SSIS doesn't give me my object but a ConnectionManager which is not a ConnectionManagerBase type... ...Show All

• Visual Studio Tools for Office VSTO SE + Office 2003 + VS 2005 Pro

  This is more of a Getting Started type of question. For some reason, I'm not finding any kind of basic tutorial that covers building an Add-In using VSTO SE (Beta) + Office 2003 Pro + Visual Studio 2005 Pro. The document that comes with VSTO SE Beta describes how to build a Ribbon, Custom Task Pane and a Custom Form Regin but all for Office 2007 components. I'd like to build an Excel 2003 add-in (or whatever) that displays a button to my end-user. Once the button is clicked I'll grab some data from the current/active worksheet, send the data to a web service and then take the results of the web service call and poke it back into the current worksheet. I've been able to do this in old school VBA (plus the now unsupported SOAP Toolkit) b ...Show All

• Visual C# SI Abbreviation Significant Number String Formating on Decimal Resolution

  Hi all, Let say I have a string formed from a double value. After a converting function to display desired quantity of significant number with SI Abbreviation. e.g. The original value is a double (12345.678). [1 significant number] : 300 m (string) [2 significant number] : 310 m (string) [3 significant number] : 312 m (string) [4 significant number] : 312.3 m (string) The problem here is that I must do the decimal resolution placing on the string only after which I get out of conversion process. The hard part is that the SI Abbreviation is attached on the output string after the significant number conversion function. I do not have access to modify the significant number conversion function. So, I must carry on modifying the output string ...Show All
