• Windows Forms AddNew in Navigation Bar - want to autofill data in bound fields

  I need to autofill a field on a data entry form after I click the "addnew" button on the Navigation Bar. (The one that is automatically generated by 2005 when I add the dataset's fields to a form.) I use the following code in a button_click function to make sure it worked, and it did. (custStr a global variable with the value I need) CustomerTextBox.Text = custStr But when I move it to this function, the value (of the CustomerTextBox.Text) filled in is blanked back out. (or never filled in at all ) Private Sub BindingNavigatorAddNewItem_Click I assume that the function above is performed before the fields are "reinitialized" and blanked out and that is why it is wiped out. So, is there a function performed ...Show All

• Visual Studio Cant find the class for embedded crystal reports?

  Hi guys. I'm having a problem finding the class for the embedded crystal report document I've added to my project. I am using VB.Net 2003 and based from the information I've got from MSDN, once you embed a crystal report into your application, a class will be automatically created for you to use to instantiate the report in your code then bind it to a crystal report viewer. But i cant find that class Say for example, ive embeded crystal report document named "CRSample.rpt" to my application. My crystal report viewer is named for example "CRVSample". I want to do it like this. Dim CRSample as ReportDocument CRSample = New [This is where the problem is. The class CRSample is suppose to be listed here after hittin ...Show All

• .NET Development Use reflection to load a VB 6.0 dll?

  Hello, I have a VB 6.0 dll thta I would like to load in a .NET project using reflection, I do not want to set a reference to it. Can it be done If yes, how I'd really apprecaite any pointers if its possible. Thank you for your time. PP. You can't use reflection to load/inspect a VB6 DLL, reflection requires a .NET assembly, VB6 DLLs are COM servers. Technically, a VB6.DLL contains a tool library as an embedded resource. You could, conceivably, get an ITypeLib interface pointer to that library. No idea how to do that. You can create an instance of a class in the VB6 DLL with the CreateObject function. That gives you a reference of type Object, fairly useless to call any metho ...Show All

• Commerce Server Working with Commerce Server tables in ADO.Net

  I've frequently run into situations where I need to retrieve data from a one of the Commerce Server databases in a production site. Unfortunately, some of this data is unavailable through the exposed runtime APIs. Occasionally, there are methods available through a management context for accessing this information, but this requires reloading the configuration settings each time one of these contexts is instantiated (which can be really, really expensive). The preferred option is therefore to work directly with these tables in ADO.Net. This is much more effecient than loading the management context objects, and allows the developer to do additional performance tuning if needed. The complication that this introduces is that it require ...Show All

• Visual C++ what is Deep Copy, shallow copy and bitwises copy.?

  what is Deep Copy, shallow copy and bitwises copy. is there any difference between them... help me. manish Shallow copy means, just bitwise copy the  objects. Deep copy means copying the content of the pointers present in your object i.e. class A {     int* p; }; main() {     A a, b;     a = b; // now a->p and b->p will point to the same location since it is bitwise copy which is not safe }   but if you define class A {     int* p;     int nSize;    operator = (A& a)    {        if(p != NULL)           delete []p; &nb ...Show All

• Visual C++ How to convert 4 types of C++ strings?

  I am new to C++ programming ... and it seems not everything is written in the books. Can anybody explain to me how to convert between the 4 types of string representations: char * char[ ] string class String ^ class Are there simple recipes for conversions Are the classes string and String^ only used with Microsoft C++, or with ANSI C++ as well It would be wonderful to get a sort of systematic overview, which I could not find in any book anywhere so far. Sounds like you want someone to write documentation for you.  There are plenty of answers out there already investigated upon and written up if you do your own searches. (This topic in fact has been covered in this forum and the MS ...Show All

• Visual Studio Team System LoadTestPageDetailData does not contain datas

  I am trying to do some report in the load Test result, I dig into the LoadTest Database and found LoadTestPageDetailData table is empty, but some of the other do have data like "LoadTestRun", The table LoadTestPageDetailData will only have data if the load test run settings have "Timing Details Storage" set to "All Individual Details". By default, it will be set to "None" and individual page response times will not be stored in the database. There is a good description of this load test setting in the following document http://msdn2.microsoft.com/en-us/library/ms404664(VS.80).aspx See the section titled "Including Timing Details to Collect Percentile Data.

• Visual Studio Tools for Office Why do MS Word Automation return different values with and without Debugger?

• Visual Studio pdb and dmp files, symbol settings, missing files ?

  Hello. I have an application that generates minidumps on crash. I am trying to analyze this dumps, but I have a problem with the symbols: I copied some generated files (.pdb, .map, .exp, .lib, vc80.pdb) to another folder, duplicating the entire source-folder structure, and I try to point to them. VS2005 debugger does not recognize the files and the call stack remains a mistery. However if I point to the original source location I get the informations I need. The difference between the source location and the new one is that the new one does not have the source files, the object files and some other files needed by the repository system. I even tried to copy the object files, but no luck. Both locations are on the intranet. A ...Show All
