• Reporting services and custom library

  - by niao

  Greetings, In my Reporting Services report I've added reference to my custom library. It works fine. I can display the string which is returned from my custom library method as follows: =ClassLibrary1.MyClass.Parse("harry potter") Above code works fine - it should return SQL query based on passed parameters. My question is, how can I use this code in my DataSource. I'm trying to do something like this: SELECT * FROM =ClassLibrary1.MyClass.Parse(@searchedPhrase) But the above code does not work and the error is returned :"Incorrect syntax near ="

• Saving a bitmap to a Memorystream produces an inverted colors image

  - by Raphael

  I've created an image with GDI+ on my application and now I must convert this image to an array of bytes. My first thought was this simple code: public byte[] ToByte() { MemoryStream ms = new MemoryStream(); bitmap.Save(ms, ImageFormat.Bmp); return ms.GetBuffer(); } The problem with this approach is that when I finally save this image into a file the colors are inverted. What I'm I doing wrong?

• Cross-thread operation not valid: Control accessed from a thread other than the thread it was create

  - by SilverHorse

  I have a scenario. (Windows Forms, C#, .NET) There is a main form which hosts some user control. The user control does some heavy data operation, such that if I directly call the Usercontrol_Load method the UI become nonresponsive for the duration for load method execution. To overcome this I load data on different thread (trying to change existing code as little as I can) I used a background worker thread which will be loading the data and when done will notify the application that it has done its work. Now came a real problem. All the UI (main form and its child usercontrols) was created on the primary main thread. In the LOAD method of the usercontrol I'm fetching data based on the values of some control (like textbox) on userControl. The pseudocode would look like this: //CODE 1 UserContrl1_LOadDataMethod() { if(textbox1.text=="MyName") <<======this gives exception { //Load data corresponding to "MyName". //Populate a globale variable List<string> which will be binded to grid at some later stage. } } The Exception it gave was Cross-thread operation not valid: Control accessed from a thread other than the thread it was created on. To know more about this I did some googling and a suggestion came up like using the following code //CODE 2 UserContrl1_LOadDataMethod() { if(InvokeRequired) // Line #1 { this.Invoke(new MethodInvoker(UserContrl1_LOadDataMethod)); return; } if(textbox1.text=="MyName") //<<======Now it wont give exception** { //Load data correspondin to "MyName" //Populate a globale variable List<string> which will be binded to grid at some later stage } } BUT BUT BUT... it seems I'm back to square one. The Application again become nonresponsive. It seems to be due to the execution of line #1 if condition. The loading task is again done by the parent thread and not the third that I spawned. I don't know whether I perceived this right or wrong. I'm new to threading. How do I resolve this and also what is the effect of execution of Line#1 if block? The situation is this: I want to load data into a global variable based on the value of a control. I don't want to change the value of a control from the child thread. I'm not going to do it ever from a child thread. So only accessing the value so that the corresponding data can be fetched from the database.

• How to make per- http Request cache in ASP.NET 3.5

  - by Artem

  We using ASP.NET 3.5 (Controls-based apporach) and need to have storage specific for one http request only. Thread-specific cache with keys from session id won't work because threads are supposed to be pooled and therefore I have a chance to have data from some previous request in cache, which is undesireble in my case. I always need to have brand new storage for each request available through whole request. Any ideas how to do it in ASP.NET 3.5?

• Is passing NULL param exactly the same as passing no param

  - by park

  I'm working with a function whose signature looks like this afunc(string $p1, mixed $p2, array $p3 [, int $p4 = SOM_CONST [, string $p5 ]] ) In some cases I don't have data for the last parameter $p5 to pass, but for the sake of consistency I still want to pass something like NULL. So my question, does PHP treat passing a NULL exactly the same as not passing anything? somefunc($p1, $p2, $p3, $p4 = SOM_CONST); somefunc($p1, $p2, $p3, $p4 = SOM_CONST, NULL);

• RDFa / Microformat - Recipe markup standards

  - by hfidgen

  I wonder if anyone can help? After Google announced that it will take note of RDFa / Microformats for online recipes, I've been looking into this for a couple of recipe based sites I run. However we simply don't have all the required data to fulfill any of the standards. Does this matter? Will search engine crawlers still make the most of what they do find, or by missing a few elements (like a review or recipe rating) will I be wasting my time implementing this? Cheers, H
