• Visual C++ Tooltips disappeared after switch from VC 6 to VC 8 due to breaking change in CWnd::OnToolHitTest()

  Hello everybody, after switching from Visual C++ 6.0 (VC 6) to Visual C++ 2005 (VC 8), many tooltips in my dialogues would not show up anymore.  It took me quite a  while to pin down the reason for this behaviour: The tooltips don't show up anymore for all child window controls which lie inside the window rect of another control like a group box or a tab control(*) preceding it in the tab order. The enclosing control has child window id IDC_STATIC, which in VC 6 meant that it was ignored by CWnd::OnToolHitTest()  (more precisely by _AfxChildWindowFromPoint(), which is used by OnToolHitTest(), see below). Now in VC 8 the constant for the controls-to-be-ignored chang ...Show All

• Windows Forms Problem calling event from control

  Hi, I have a control, SimpleSplitter , that derives from Splitter where I override the OnMouseDown , OnMouseUp , OnMouseSplitterMoved and OnSplitterMoving . I do this because I don't want the Splitter to handle these for me since it will draw what I call a shadow splitter when handling these events. So I wanted to still handle the event but not call the OnMouseDown of the Splitter , instead, I wanted the parent of the Splitter , that is the Control . I'm not seeing how I can do this. If you don't understand what I mean, you have the code here: http://n0n4m3.gamedev-pt.net/ pag=managed_component2&language=en The solution I used was to create a new event, MouseDown2 , but I don't like this solution and I think there's a better one.

• .NET Development URGENT Assembly.LoadFrom(http) == "Could not load file or assembly 'X' ... or one of its dependencies."

  [Runtime Version v2.0.50727] Question regarding Assembly.LoadFrom(http). This really is URGENT; thank you for your time. Hello, I have three projects: X, Y and Z. Project X is a class library-type project full of user controls that other developers monkey with; these controls obey a set interfaces we have defined in project Z. Project Y is a winforms-type project. It does not contain a reference to Project X, but it does contain a reference to project Z - just like project X does. Project Y loads Project X dynamically from a HTTP using the following code: /// * start sample string _Url; _Url = " http://localhost/projects/ProjectX.dll "; System.Reflection.Assembly _ProjectX; _ProjectX = System. ...Show All

• Windows Forms ClickOnce Publish Version Problem

  I am currently using .Net 2005 Professional (see Info below). Microsoft Visual Studio 2005 Version 8.0.50727.42 (RTM.050727-4200) Microsoft .NET Framework Version 2.0.50727 I am using ClickOnce to publish new versions to a local web site. Lately whenever I publish, the solution builds just fine, but attempts to publish an older version (1.1.2.33) even though I have manually set the Publish Version (in the Publish tab in Project Properties dialog) to 1.1.2.42. It appears that regardless of the version I enter in the property, I get the same error message: Published version 1.1.2.41 will be replaced by an older version (1.1.2.33).

• .NET Development Get AbsoluteRange of a NamedRange Using OLedb, Excel

  I am currently using OLEDB to read the data from excel using C#. I have a scenario in which i will pass a NamedRange and I need to get the data from the NamedRange and also I need to read the data from the cell adjacent to the NamedRange. What I was planning to do is to get all the data in a dataset and then if I have the absolute range information of a NamedRange, i can filter the dataset based on that and i can read the cell adjacent to it from the dataset. But now am not able to find any way to get the absolute range of a named range. I have tried using " GetOleDbSchemaTable", but it will provide the absolute range information only if there are header information in Excel.Else it will return default values F1, F2..etc. ...Show All

• Windows Forms Two way databinding doesn't work?

  Hi guys I have a class which has a Dob (date of birth) property with validation rule (If user select a date early than 1920/01/01, reset the value to 1920/01/01. If user select a date later than .... ) inside it. Then I bind it to a Windows.Forms.DateTimePicker control and found out that the validation rule works but the new value won't be displayed on the DateTimePicker control until I manually call Form.validatechildren or Bindsourse.ResetItem method in Validated event of the DateTimePicker control. What do you guys think By the way, Yes, I do have INotifyPropertyChanged interface in the class and it works very well except the above problem. And also I know I can use the MaxDate/MinDate properties of DateTimePicker control in ...Show All

• Visual C++ Incrementation

  Hi, int i=0; int j=++(++i) + ++(++i); Can anyone explain me why j=8 thanks! I believe code like this is implementation dependent--which version of i during the preincrementation is decided by the compiler.  But the current behavior is what you *should* expect from a compiler that produces the best code by avoiding making temporary copies.  By stepping through disassembly, you can infer how the compiler interprets this. By moving preincrements to their own lines, this code is equivalent to: ++i;  // note that this expression evaluates to a reference to i itself, which carries a new value. ++i;  // increment that reference ++i;  // this uses the refernence to the n ...Show All

• Windows Forms Concurrency violation help me please

Hi, Concurrency exceptions only happen if the data in the DB doesn't correspond to data in the DataSet's "Original" version. So, either the "Original" version of the data is changed in the DataSet, or the data in the DB is changed by some "external" action. I know Access DB's don't support triggers, ...Show All
