Hi All, You can modify value of 'AppSettingsSection' by below code. ConfigurationSectionGroup sectionGroup = config.SectionGroups["applicationSettings"]; ClientSettingsSection section = (ClientSettingsSection)sectionGroup.Sections["....Settings"]; section.Settings.Get("GeneratePDF...").Value.ValueXml.InnerText = urlname; config.Save(ConfigurationSaveMode.Minimal, true); -Thomas :)

How to use ConfigurationManager to modifying "applicationSettings" section of App.config? Or it there any other way to do same? I have the code to modify "appSettings" section of app.config. 1) To modify key "SApp.Properties.Settings" of "appSettings" section of app.config I used below code:: ExeConfigurationFileMap fileMap = new ExeConfigurationFileMap(); fileMap.ExeConfigFilename = @"D:\app.config"; Configuration config = ConfigurationManager.OpenMappedExeConfiguration(fileMap, ConfigurationUserLevel.None); AppSettingsSection section = (AppSettingsSection)config.GetSection("appSettings"); section.Settings["SApp.Properties.Settings"].Value = "i23"; config.Save(); 2)My App.config has below content:: <?xml version="1.0" encoding="utf-8"?> <appSettings> <add key="SApp.Properties.Settings" value="http://2344/soap/services"/> </appSettings> <applicationSettings> <Generate.Properties.Settings> <setting name="Generate_GeneratePDFServiceService" serializeAs="String"> <value>http://2435/GeneratePDFService</value> </setting> </Generate.Properties.Settings> </applicationSettings>

A) There is a webservice and I am writing a client in c++ to invoke that webservice using IDispatch. I have taken the sample for c++ client from codeproject and below is the link [http://www.codeproject.com/KB/COM/xysoapclient.aspx? fid=13980&df=90&mpp=25&noise=3&sort=Position&view=Quick&fr=26&select=516139](http://www.codeproject.com/KB/COM/xysoapclient.aspx?<br mode=)[[^](http://www.codeproject.com/KB/COM/xysoapclient.aspx?<br mode= "New Window")] This is structure we pass in c# for calling method [System.Xml.Serialization.XmlTypeAttribute] public class BLOB { /// <remarks/> public string contentType; [System.Xml.Serialization.XmlElementAttribute(DataType="base64Binary")] public System.Byte[] binaryData; public string ID; public string URL; } B) Regarding writing a client in c# for webservice is pretty straight forward. In C# it is pass complex data in single argument. OR If above is complex is anyone know how to pass structure like below in IDispatch's Invoke() method. The COM Server is third party. struct tag{ char str[100]; void *p; char str1[300]; }

How To pass structure or complex data in IDispatch using invoke() method. The COM server component is third party's so I donot have control on what defined in IDL or whatever technology they used. for example I want to pass complex data or structure like below to invoke() method. struct tag{ int i[10]; char str[40]; }sample; Below is sample code to access method passing argument. // Code omitted for brevity. szMember = “On”; dispparams.rgvarg[0].vt = VT_BOOL; dispparams.rgvarg[0].bool = FALSE; dispparams.rgdispidNamedArgs = &mydispid; dispparams.cArgs = 1; dispparams.cNamedArgs = 1; hresult = GetIDsOfNames(IID_NULL, &szMember, 1, LOCALE_USER_DEFAULT, &dispid); hresult = pdisp->Invoke( dispid, IID_NULL, LOCALE_USER_DEFAULT, DISPATCH_PROPERTYPUT, &dispparams, NULL, NULL, NULL); I need to pass one argument in IDispatch's Invoke method as below . This is sample code from c# client. I already have client C# code working. I want to pass structure which has byte array and string etc in c++ using IDispatch. How usually people pass structure as single argument in IDispatch's Invoke method() public class BLOB { /// <remarks/> public string contentType; public System.Byte[] binaryData; public string ID; public string URL; } OR If above is complex is anyone know how to pass structure like below in IDispatch's Invoke() method. The COM Server is third party. struct tag{ char str[100]; void *p; char str1[300]; }

I tried with Admin user, local System account and tried direct path also like "\\server\public_data\hello.txt" but no use. It has problem when running as a service in win2003k and as standalone no problem. do anyone know how to give more permissions to services in win2003k os?

is there any way to use it as service instead of standalone

Hi friends, There is problem in accessing mapped drives or remote machine from my vc++ service in Windows Server 2003 OS for example when I execute my program as services it fails but I am not facing any problem if I execute it as standalone program. I am having admin privilege. Below is the few of API I tried (where is S: is mapped drive in same domain) API: CreateFile and GetFileAttributes("S:\hello.txt") Thanks, Thomas
