Hi,
Is it possible to convert a .wmf file to Base64String?
Thanks
|
|
|

Yes: all files are just a stream of byte values - it's the interpretation that software puts on the internal format of those bytes that makes it a "WMF" or "JPG" file. The extension just indicates what format the software should look for.
string base64 = Convert.ToBase64String(file.ReadAllBytes(@"D:\Temp\myPicture.wmf")); However, that doesn't mean that whatever you pass the base64 string to can do anything useful with it. For example, not all browsers support WMF file data in any format, and changing it to Base64 will not fix that. WMF is pretty much a "Windows only" image format: you would probably be better off using a more generic format such as JPG, GIF, or PNG.
Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...

Thanks very much!
How do I load it back to a form?

I more concern. 
I want the metafile to be created in memory rather than saving to a disk. It should be a blank metafile. I assume it is like this.
metfile = New Metafile(hdc, EmfType.EmfPlusDual)

Hi,
I have a web service which returns JSON string like this:
{
"valid": true,
"messages": [
"Cannot validate bank code length. No information available.",
"Cannot get BIC. No information available."
],
"iban": "BH00000000000000000000",
"bankData": {
"bankCode": "",
"name": ""
},
"checkResults": {
"bankCode": false
}
}
I am able to get it using below code:
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://openiban.com/validate/" + txtIBAN.Text.Trim());
try
{
WebResponse response = request.GetResponse();
using (Stream responseStream = response.GetResponseStream())
{
StreamReader reader = new StreamReader(responseStream, Encoding.UTF8);
string strsb = reader.ReadToEnd();
}
}
catch (WebException ex)
{
WebResponse errorResponse = ex.Response;
using (Stream responseStream = errorResponse.GetResponseStream())
{
StreamReader reader = new StreamReader(responseStream, Encoding.GetEncoding("utf-8"));
String errorText = reader.ReadToEnd();
}
throw;
}
but I want to know can I now read the value valid if it's rue or false?
Thanks,

Use Json.NET[^] - you can add a reference via NuGet[^]:
Install-Package Newtonsoft.Json
You can then either use LINQ to JSON[^] to read the property:
JObject result = JObject.Parse(strsb);
bool isValid = (bool)result["valid"];
or create strongly typed classes to represent the result:
public class ResponseData
{
public bool valid { get; set; }
public IList<string> messages { get; set; }
public string iban { get; set; }
public BankData bankData { get; set; }
public IDictionary<string, bool> checkResults { get; set; }
}
public class BankData
{
public string bankCode { get; set; }
public string name { get; set; }
}
...
var result = JsonConvert.DeserializeObject<ResponseData>(strsb);
bool isValid = result.valid;

To add to Richard's answer, you can use this free handy-dandy online tool to generate C# classes from JSON. You may want to rename the generated class names to be more developer friendly.

When I look at the message text above, I think you can get confused by their convention. Their "valid": true seems to mean that the message you sent them was syntactically correct. But you are likely interested in the IBAN. And that's given in a different part of the message: "checkResults": { "bankCode": false }.
Well, I tried that service with my IBAN, and got following result (I edited the number on the response below):
{
"valid": true,
"messages": [],
"iban": "DE...........",
"bankData": {
"bankCode": "",
"name": ""
},
"checkResults": {}
}WTF... A valid IBAN is indicated by an empty checkresult and an empty messages array.

Hindi SMSes would be sent as a Unicode SMS (UCS2 encoding). If you have a basic SMS sending package, see 3GPP TS 23.038 (available for free at www.3gpp.org[^]) for the details that must be changed in the SMS fragment's header.
If you have an important point to make, don't try to be subtle or clever. Use a pile driver. Hit the point once. Then come back and hit it again. Then hit it a third time - a tremendous whack.

Is there a way to accomplish that a sequence of code does run exclusively, I mean no Task scheduling allowed while executing the sequence?
The reason behind it is, I try to determine the memory usage of a class this way:
private void MemoryTest()
{
const int cTestObjCount= 10000;
long before= GC.GetTotalMemory(false);
string[] stringArray= new string[cTestObjCount];
long after= GC.GetTotalMemory(false);
}
Or does somebody knows a better method how to determine the memory consumption of a class (without the help of a profiler)?
Thank you in advance.

There is no way to prevent this in the .NET framework. Thread switching is in the control of the OS.

The only reliable way would be to use a memory profiler. Either CLR Profiler[^] or PerfView[^] should do the job.

Error :The type or namespace name 'Contract_Kind' could not be found (are you missing a using directive or an assembly reference?)
///
/// Gathers values from contract kind checkboxes (Forex, Equity, Options)
///
private IEnumerable<contractkind> GetSelectedContractKinds()
{
if (chbFutures.Checked)
{
yield return Contract_Kind.Future;
yield return Contract_Kind.FutureCompound;
yield return Contract_Kind.GenericCompound;
}
if (chbForex.Checked)
{
yield return Contract_Kind.Forex;
}
}
}
Can somebody help me to fix this ERROR.

The error is fairly self-explanatory - you're trying to use a type called Contract_Kind which doesn't exist.
Either:
- you're missing a reference to the assembly where the type is defined; or
- you're missing a
using statement for the namespace where the type is defined; or - you've got the wrong type name; or
- you haven't written the type.
We can't see your code, so we can't tell you which of those options is the case.

I have nested classes Inner class which is inherited by outer class. Inside inner class I have 2 integer properties. Which I use in Outer class to create 2 timer types.
Inner
Elapsed Time
Total Time
Outer class:
Inner inner1
Inner inner2
I use a loop to increment and update elapsed time property on inner1 of the outer class. The property updates, however the onproperty change event does not fire for the Outer class.
How do I bubble up the onproperty change event inorder to trigger the onproperty change event for my outer class.

This is usually done by creating a delegate and subscribing to the event. There is a tutorial on the subject at Delegates Tutorial (C#)[^].

This does not make sense, please describe what your classes are, and which classes inherit from other classes.
Clarify whether you are talking about the outer class containing instances of the inner classes, or containing the actual definition of the inner classes.
Describe where and how you have implemented property notification change code.
