Hello Ravi, Thanks for your guidence, but actually what I want is to enable or diable existing BHO in IE as we are making an Browser add-on manager. When existing BHO is enabled or disabled its entry is modified in HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Approved Extensions but we are not able to understand the value data information inside it. If you can put any light on it, It would be a great help.

Hello Guys, We are developing an antispyware program in .net and i want to register my product for listing it into windows security center. I Searched a lot about it and got some idea that it can be done through WMI by \\root\SecurityCenter2 namespace and antispywareproduct class. But all i found was to get the information for antispywareproduct class. Can any one tell me how to add my product to this table. any ideas will be a great help. Regards

Hello guys, Need some expert advise. I am developing a c# windows application which runs as administrator. The problem is on windows 7 and Vista, drag and drop on the application do not works when UAC is enabled. I researched a lot and found that this is because of UIPI (User Interface Privilege Isolation) and on MSDN I found some information asking to allow the filtered messages again by using ChangeWindowMessageFilter API. I tried it and called it on form_load event some thing like this private const uint WM_DROPFILES = 0x233; private const uint WM_COPYDATA = 0x004A; private const uint MSGFLT_ADD = 1; //in form load i called ChangeWindowMessageFilter(WM_DROPFILES, MSGFLT_ADD); ChangeWindowMessageFilter(WM_COPYDATA, MSGFLT_ADD); ChangeWindowMessageFilter(0x0049, MSGFLT_ADD); But it still dont work.. may be i am missing some thing, I tried to set the property uiAccess="true" also in the manifest file and signed the exe but it still dont work. Am i calling the ChangeWindowMessageFilter incorrectly or is there any another way ? Can any one help me regarding this. I had to run the application as administrator as it modifies some registries Any help would be great Thanks in advance Regards

Hello Guys, Need some help from you guys. I have Generic List having a Class object. I have added around 3000000 items in the list List <CTempClass> lsTemp = new List <CTempClass> (); when i tried to Serialize the with binary formater it is working fine but when I deserialize the List it takes a lot of time around 30 Seconds. But when i fill the Generic List with any datatype like List<ulong> lsTemp = new List<ulong>(); and follow the same procedure the speed difference is drastic the while thing deserializes in 1 -2 Seconds My Class object is Declared Serializable. I dont understand why it is serialzer is behaving like this. Am i Missing something. Here is the Sample Code : List<CTempClass> lsTemp = new List<CTempClass>(); for(int i=0; i < 5000000;i++) { CTempClass oTemp = new CTempClass(); oTemp.ID = i; lsTemp.Add(oTemp); oTemp=null; } using (Stream stream = File.Open("c:\\data.bin", FileMode.CreateNew)) { BinaryFormatter bin = new BinaryFormatter(); bin.Serialize(stream, lsTemp ); } //this takes a lot of time using (Stream stream = File.Open("c:\\data.bin", FileMode.Open)) { BinaryFormatter bin = new BinaryFormatter(); var lsTemp1 = bin.Deserialize(stream); } here is the code of temp class [Serializable] public class CTempClass : ISerializable { // public int nId; private ulong m_uCrc64; public CTempClass () { m_uCrc64 = 0; } //Deserialization constructor. public CTempClass (SerializationInfo info, StreamingContext ctxt) { //Get the values from info and assign them to the appropriate properties m_uCrc64 = info.GetUInt64("m_uCrc64"); } //Serialization function. public void GetObjectData(SerializationInfo info, StreamingContext ctxt) { info.AddValue("m_uCrc64", m_uCrc64); } } Can any one please tell me why it is taking so much of time. Any suggestion will be a great help
