  • ASP: using existing Crystal Report with date parameter

    - by eric3141
    I have an existing Crystal Report done in Crystal Reports version 9. I need to display it via an ASP website created in Visual Studio 2008. I have put the Crystal data source and viewer controls on the design page and configured the controls to use the crystal report but cannot seem to figure out how to pass a date to the report which uses it as an input parameter for a SQL Server 2005 stored procedure. I have tried putting a calendar control on the design page but don't know how to use it to pass the date parameter. Thanks in advance for any help. Eric

  • Why is MenuItem.AdapterContextMenuInfo null when my list view has a custom adapter?

    - by gregm
    My question: Before I go and use an OnLongClickListener, is there a better way to pass the "what was clicked to create this context menu" information when your list view has a custom adapter? Here are some details: Normally, my code can just do something like this: public boolean onContextItemSelected(MenuItem item) { AdapterContextMenuInfo info = (AdapterContextMenuInfo) item.getMenuInfo(); and then go on and be happy. However, ever since I introduced a custom adapter, item.getMenuInfo() is null. This is a big problem, because my code no longer knows which item was clicked. (My custom Adapter makes each list row a checkbox and a text view) I tried this but failed: Created my own special AdapterContextMenuInfo (called "HasAViewMenuInfo"), but when I pass it in this method, it ends up being null in the menu public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) { super.onCreateContextMenu(menu, v, new HasAViewMenuInfo(v));

  • Passing javascript to a function

    - by AJ
    Hello, Can I pass some Javascript to a function and then execute that Javascript from within the function, e.g. test("a = 1; b = 2; test2(a,b);"); function test(js) { // execute dynamically generated JS here. } Basically I have some code that is generated on the server and I want to pass that code to a JS function which when it has finished processing it executes the code passed as a parameter. This could also be useful for the parameter of setTimeout, then the code passed could be executed in the timeout event. Can this be done?

  • Connecting flex/php to Active Directory

    - by modz0r
    Is there a way to connect my flex web application to Active Directory, and get the logged username? Right now we have a PHP script connected to the flex application, that gets user/pass input from the user and checks if there's such user in the AD, and that the password is correct. I don't want to ask for user/pass, but to make the application get the domain username that connected to it, so I could use it (check if the user has access to my application and such). Is there a way to do so?

  • Is it thread safe to read a form controls value (but not change it) without using Invoke/BeginInvoke from another thread

    - by goku_da_master
    I know you can read a gui control from a worker thread without using Invoke/BeginInvoke because my app is doing it now. The cross thread exception error is not being thrown and my System.Timers.Timer thread is able to read gui control values just fine (unlike this guy: can a worker thread read a control in the GUI?) Question 1: Given the cardinal rule of threads, should I be using Invoke/BeginInvoke to read form control values? And does this make it more thread-safe? The background to this question stems from a problem my app is having. It seems to randomly corrupt form controls another thread is referencing. (see question 2) Question 2: I have a second thread that needs to update form control values so I Invoke/BeginInvoke to update those values. Well this same thread needs a reference to those controls so it can update them. It holds a list of these controls (say DataGridViewRow objects). Sometimes (not always), the DataGridViewRow reference gets "corrupt". What I mean by corrupt, is the reference is still valid, but some of the DataGridViewRow properties are null (ex: row.Cells). Is this caused by question 1 or can you give me any tips on why this might be happening? Here's some code (the last line has the problem): public partial class MyForm : Form { void Timer_Elapsed(object sender) { // we're on a new thread (this function gets called every few seconds) UpdateUiHelper updateUiHelper = new UpdateUiHelper(this); foreach (DataGridViewRow row in dataGridView1.Rows) { object[] values = GetValuesFromDb(); updateUiHelper.UpdateRowValues(row, values[0]); } // .. do other work here updateUiHelper.UpdateUi(); } } public class UpdateUiHelper { private readonly Form _form; private Dictionary<DataGridViewRow, object> _rows; private delegate void RowDelegate(DataGridViewRow row); private readonly object _lockObject = new object(); public UpdateUiHelper(Form form) { _form = form; _rows = new Dictionary<DataGridViewRow, object>(); } public void UpdateRowValues(DataGridViewRow row, object value) { if (_rows.ContainsKey(row)) _rows[row] = value; else { lock (_lockObject) { _rows.Add(row, value); } } } public void UpdateUi() { foreach (DataGridViewRow row in _rows.Keys) { SetRowValueThreadSafe(row); } } private void SetRowValueThreadSafe(DataGridViewRow row) { if (_form.InvokeRequired) { _form.Invoke(new RowDelegate(SetRowValueThreadSafe), new object[] { row }); return; } // now we're on the UI thread object newValue = _rows[row]; row.Cells[0].Value = newValue; // randomly errors here with NullReferenceException, but row is never null! }

  • Sending data between activities within my app?

    - by user246114
    Hi, I have a TabActivity, and the tabs point to sub activities. Is there a way I can send a 'message' to those child activities? I just want to pass a string across, not sure if this is possible. I have some data being fetched by the parent TabActivity, and the child tabs can't do anything useful until the parent is done fetching. When fetching is complete, I'd like to pass that data to the child activities so they can do something useful with it. Notmally I'd set the data to be passed in the Intent when first creating the activity, but in this case I can't do that. Thanks

  • What are the disadvantages of using a StringBuilder?

    - by stickman
    I know that StringBuilder is more efficient than a normal string when processing code which modifies the string value a lot because although strings act like value types, they are actually reference, which makes them immutable so every time we change it, we need to create a new reference in memory. My question is that, why doesn't .NET just use stringBuilder by default? There must be some disadvantages of it over just using String. Can anyone tell me what they are? The only thing I can think of is perhaps it is a heavier object and it takes more time to instantiate so if you aren't changing the string too much, this would override the benefits of StringBuilder

  • Program not running from expected directory?

    - by twpc
    I am working on a web-based program, using Java. I am not sure exactly how to phrase this, but I expect the program to be running from within the c:/Resin/webapps/apps directory. However, when I reference a file in the program like this: "../files/randomfile.pdf", it cannot find that file. It works when I reference it like this: "c:/Resin/webapps/files/randomfile.pdf". How to I change the "running location"? (And what is the technical term for this?)

  • Handling multiple post-defined datasource connections based on user

    - by choudeshell
    How should I handle multiple user-connection defined datasource connection in my .NET application? To illustrate this better; the user provides three (3) pieces of information, username, password and data source name. This data source name is then looked-up in a central database telling that application which main database this user should connect to. My question is, in the DataAccess layer, should we only pass down enough information to uniquely identify that user, and query the central database each time in the DAL; or, should we provide another way to pass the datasource connection down to the DAL?

  • Subtype polymorphism and arrays

    - by user133466
    Computer[] labComputers = new Computer[10]; with public class Computer { ... void toString(){ // print computer specs } } public class Notebook extends Computer{ ... void toString(){ // print computer specs + laptop color } } each subscripted variable labComputers[i] can reference either a Computer object or a Notebook object because Notebook is a subclass of Computer. For the method call labComputers[i].toString(), polymorphism ensures that the correct toString method is called. I wonder what if we do Notebook[] labComputers = new Notebook[10]; what kind or error would I get if I reference with Computer object and a Notebook object

  • Can I just release the top object (iPhone)?

    - by yar
    If I release the object that's holding a reference to the variable that I need to release, is that sufficient? Or must I release at every level of the containment hierarchy? I fear that my logic comes from working with a garbage collector for too long. For instance, I assigned to this property of a UIPickerView instance by hand instead of using IB @property(nonatomic, assign) id<UIPickerViewDelegate> delegate Since it's an assign property, I can't just release the reference after I assign it. When I finally release my UIPickerView instance, do I need to do this: [singlePicker.delegate release]; [singlePicker release]; or is the second line sufficient? Also: Are these assign properties the norm, or is that mostly for Interface Builder? I thought that retain properties were the normal thing to expect.

  • How to identify each parameter type in a C# method?

    - by user465876
    I have a C# method say: MyMethod(int num, string name, Color color, MyComplexType complex) Using reflection, how can I distinctly identify each of the parameter types of any method? I want to perform some task by parameter type. If the type is simple int, string or boolean then I do something, if it is Color, XMLDocument, etc I do something else and if it is user defined type like MyComplexType or MyCalci etc then I want to do certain task. I am able to retrieve all the parameters of a method using ParameterInfo and can loop through each parameter and get their types. But how can I identify each data type? foreach (var parameter in parameters) { //identify primitive types?? //identify value types //identify reference types } Edit: this is apart of my code to create a propert grid sort of page where I want to show the parameter list with data types for the selected method. If the parameter has any userdefined type/reference type then I want to expand it further to show all the elements under it with datatypes.

  • C++ convert formatted string to a stream

    - by Roey
    Hi All, I'm using VS2008 C++. As I understand it there is no way to pass something like this in a C++ stream : (without using external libraries) "number " << i <------ when i is an integer. So I was looking for a better way to do this, and I all I could come up with is create a string using : char fullstring = new char[10]; sprintf(fullString, "number %d", i); .... pass fullstring to the stream ..... delete[] fullString; I know it's stupid, but is there a better way of doing this?
